I want to upgrade my echo 1 mk14 combat master but am not sure I'm looking at the correct parts or have a good idea as for what to upgrade as I will be using it both close quarters and as a sniper. I'm thinking of upgrading the barrel to a 6.03 as it is accurate already with a 6.05 stock barrel. Any help is appreciated thank you. And yes I am a new player, my brother got me started with the sport.

DBOYS Full Metal RK-01 WS Steel Version AKS 74 UN CQB Folding Stock I bought this new 6 months ago and I’m eliminating anything in my arsenal that isn’t ‘standard’ M4 gear to pay for an HPA conversion and to standardize my gear. I bought it from AirsoftGI: http://www.airsoftgi.com/product_info.php?products_id=2903 This shoots fast, hard, and straight. It has only been skirmished once and it performed very well. I will include the High Cap DBOYS mag for the price of $199 (see below, I have $319++ into it). I will add the 3 mid-cap G&P mags and 2 high-cap zip mags for an additional $50 to make the package $249. If you are familiar with these mags, you know they cost around $15 each, so this price is a bargain. That is the price with the gun…until the gun is sold, I won’t sell the mags separately. This is the full steel and real wood version (not the cheapo Pot Metal version) which is both more solid and long-lasting. I have upgraded just about everything in the gearbox and electrical including: New Gears ($20) New piston and head ($18) New cylinder head and air nozzle ($15) New selector plate ($8) New trigger switch ($8) New Motor ($30) New Mosfet (it is crazy-fast with the 11.1 battery now) ($20) New wiring throughout Moved battery to rear and added pouch so I could use any battery I wanted rather than being stuck with those stupid low capacity stick batteries Tight Bore Stainless Steel Barrel ($30) New Metal hopup ($15) Flat-hopped Modification Newly Shimmed and GreasedTotal of my costs for the Gun plus upgrades: $319 (not including tax, shipping, and a ridiculous amount of time/labor). Again, I am selling with one high-cap mag for $199 or with all mags shown for $249. Please let me know what questions you have or if you want to see it.

I’m eliminating anything in my arsenal that isn’t ‘standard’ M4 gear to pay for an HPA conversion and to standardize my gear and reduce the long-term cost of maintenance. http://www.airsoftgi.com/product_info.php?products_id=9253 Price: $149 (compare to $250+ without improvements online) This is a super solid gun with the following upgrades: Added lower rail for attachment of vertical handgrips and such. At the moment, it is attached at a 45 degree angle because I like that position for the vertical grip. But, it can be moved to the bottom for completely vertical orientation. CNC Metal Hopup and air nozzle. The original hopup is back on it currently because, oddly, it performs better with the original hopup. But, the CNC hopup is included should you choose to use it in the future. New piston, piston head and cylinder head Added external battery pouch because I like to use bigger batteries and the space in the handguard is limited to smaller batteries. If you don’t like this pouch, the wiring is totally and easily reversible.It is a great gun that shoots straight and accurately/consistently.

I’m eliminating anything in my arsenal that isn’t ‘standard’ M4 gear to pay for an HPA conversion and to standardize my gear. I am asking $150 though I have $250+ into it. It includes a G36 high cap mag and an M4 magwell converter. There are lots of upgrades including including: M4 Mag Well Conversion Unit (allows you to use M4 mags rather than the G36 ones) ($25) New Gears ($20) New piston and head ($18) New cylinder head and air nozzle ($15) New selector plate ($8) New Mosfet ($20) New spring and guide Moved battery to external pouch so I could use any battery I wanted rather than being stuck with the tiny low capacity batteries that would fit in the handguard Newly Shimmed and GreasedTotal of my costs for the Gun plus upgrades: $260 (not including tax, shipping, and a ridiculous amount of time/labor). Please let me know what questions you have or if you want to see it.

Hi I have had my Jg mp5 for a year now and I thought why not upgrade it and show it some love. Not a bad idea because I am going to Mad Max this week and I thought why not upgrade it and use it at an event. The upgrades that I got were a new barrel it is a 6.01 tight bore mad bull 363 mm ( to make a compression it is way longer than the stock barrel I cant rember off the top of my head on how long it is) and a silencer 150 mm. Also some other little gear but those two were for my mp5 only. The bb's i got were .23g Matrix, after installed the new barrel and put the flash hider on I went out to shot it and litter it only went 5 to 10 feet and that's all. So I don't know what happened and I need it to be fixed by Friday. My whole goal was to shoot farther than before and increase my fps by a little that's all and now I can out shoot by just throwing them . So if anyone knows whats wrong with it please help. Also my battery was fully charged. Also I got a sniper that is not working but I will make a new post for that.

Ok so I am in some trouble... I am awful with internal upgrade choices and whatnot. I have a Magpul King Arms S&W M&P15 MOE PTS M4: http://www.airrattle...-p/kaag52bk.htm But anyways I need some advice from you gun techs. I need alot of advice... I want my gun to still keep its good ROF but I am willing to sacrifice some of it for range and accuracy. I also run a 9.6v 1600mAh battery. But also I was wondering if I could run a 7.4v lipo in the stock if I rewire it to the buffer tube because I wanted to put a 10 inch Omega rail for the handguard but obviously you can't open it up like a delta ring type thing. So anyways just give me advice gun techs on what internals I should put in my gun for pretty good ROF and good accuracy and range. Thanks! -AmazingAirsofter

Hello everyone, I offer a line of products produced, sourced, and/or assembled by myself as well as basic to advanced airsmithing services. Many of these products cannot be found in conventional airsoft stores, cannot meet my stringent quality and performance standards, or cannot be found for remotely reasonable prices, ergo why I have developed my own. To order, send me a PM with what you want and then we can work out payment details. I only accept PayPal payments at this time. Unless otherwise noted, shipping is not included in any listed prices. International orders are subject to additional shipping fees. Credit to the person(s) whose original concepts are implemented or adapted from is listed at the end of each listing. PRODUCTS Unless otherwise noted, all products come with a 30-day limited warranty. See warranty conditions at the bottom of this post. 1. Cleaning/Unjamming Rods The Jonezy Rod. Sometimes, it's the little things that get overlooked. Things like the cleaning/unjamming rod. The ones that come with most guns are delicate and brittle, making them hardly suitable to take out on the field with you. Some don't even come with cleaning/unjamming rods right out of the box and whenever you buy a used gun, it likely won't come with one. Once upon a time, Moondog Industries offered a coilable unjamming rod made of hollow plastic tubing. It had two major flaws: the tubing would bend and collapse if you put too much pressure on it and it lacked an angled unjamming end and an eyelet for cleaning. By combining the coilable feature of the Moondog offering with the slanted ram and eyelet from standard cleaning rods, I created the Jonezy Rod. It is made entirely of strong, flexible nylon as opposed to the cheap plastics found in that cleaning rod you broke or can no longer use effectively after you put a longer inner barrel in. Each comes with a Velcro loop to fasten the coil together. Available for the following barrel lengths (extra length added for average flash suppressors): 205mm (UMG): $10.30 229mm (MK5, AKS74U): $10.80 247mm (E90, MK36C): $11.35 285mm (MC51): $12.15 305mm (SBR, VSR10 G-SPEC, M733, CQBR): $12.85 363mm (M4, SR16, SG551): $14.25 455mm (AK47, M14SOC): $16.30 510mm (M16, Type 96, M14, AUG): $17.60 560mm (VSR10): $19.00 610mm (PSG-1): $24.00 650mm (PSG-1+) $24.70 Shipping is NOT included in the prices listed above. All other lengths not listed here are priced with the following formula: Price = 0.03 x (inner barrel length + flash suppressor or barrel shroud length) + 4.30 Don't want the Velcro strap or a specific end? Let me know and I'll adjust the price accordingly. If you have a barrel extension or abnormally long flash suppressor, PLEASE LET ME KNOW AHEAD OF TIME AND PROVIDE A MEASUREMENT OF IT! I can easily account for the added length and it'll keep you from having to exchange it out. Credit to: Moondog Industries, bane901 (Airsoft Ohio) 2. Simplex Basic MOSFET Units Simplex Basic MOSFET Unit next to a pair of Deans connectors for size comparison. Close-up of above. Simplex Basic MOSFET Unit next to a pair of Deans connectors for thickness comparison. ***The Basic MOSFET Units have been discontinued in favor of the new Simplex Basic MOSFET Units*** MOSFETs are a fundamental part of any AEG you plan on running anything higher than a small 9.6v battery in. A MOSFET handles the current switching internally and uses the trigger switch in your gearbox to tell the unit when to turn on, preventing this from happening over time: Burnt trigger contacts. Image courtesy of HeXeD from Airsoft Forum. My MOSFETs are built to operate on up to 14.8v batteries and in some of the most demanding setups on the field. Each unit comes with 2' 16AWG low-resistance wire leads for the main wires and a 2' 24AWG super thin wire lead for the gate. Every MOSFET unit is hand-assembled and tested to ensure complete functionality. A large TVS diode filters out voltage spikes and interference created by the motor and safeguards the MOSFET from gradual damage, a feature the Infected Armory MOSFET units lack. PLEASE NOTE: These units do not support active braking (AB) features. Technical Specs: MOSFET used: IRLS3034PbF Max. voltage: 40V (14.8V recommended) Max. amperage: 195A (35A recommended) Dimensions: 14.5mm length x 12.75mm width x 8.25mm height Wire used (source and drain only): 16AWG PVC insulated fully annealed tinned stranded copper Stranding: 26/30 Outer diameter: 2.34mm Lead length(s): 2' each Wire used (gate only): 24AWG PVC insulated fully annealed tinned stranded copper Stranding: 7/32 Outer diameter: 1.42mm Lead length(s): 2' To install, you must have a soldering iron, solder (60/40 alloy preferred), wire cutters, wire strippers, and basic soldering skills. Your stock trigger switch is configured like this with one red positive wire coming in from the battery and one red positive wire leaving the switch to the motor: Stock trigger switch wiring. To install a Simplex Basic MOSFET Unit, de-solder one red positive wire from one side of the switch and solder it to the other. Then, solder the small green gate lead to the empty side like so: Basic MOSFET trigger switch wiring. It is often beneficial to re-wire the entire gearbox with the same low-resistance wire used for my MOSFET units and polyfuses. All wire (gate, red positive, and black negative) is $0.52 per foot. All MOSFETs are now backed with a 30-day limited warranty. Available in the following configurations: Standalone (no fuse): $18.00 each shipped With 20, 24, or 30A self-resetting fuse: $28.00 each shipped 3. Self-Resetting Polyfuses 30A self-resetting polyfuse next to a set of Deans connectors for size comparison. Close-up of the above. Self-resetting polyfuse installed in a KWA KM4. When a disposable tube or blade fuse blows on the field, you're in for a lengthy walk back to the staging area to dig for a replacement in a best case scenario. For those that would like to avoid this while lowering electrical resistance, I offer self-resetting polyfuses. These fuses heat up in the event that your AEG starts drawing too much current and break the circuit immediately to stop the AEG from operating. This can prevent further damage to your AEG in the event of an electrical or mechanical failure. Each comes with two 2' 16AWG low-resistance wire leads to fit nearly any layout. Available in the following trip ratings: All fuses are $10.00 shipped within the continental United States. 20A (for most stock AEGs) 24A (for lightly upgraded AEGs) 30A (for heavily upgraded AEGs) Credit to: Terry Fritz 4. Hopup Tracer Units (HUTU) From left to right: Metal AK HUTU, Metal M-Series HUTU, Polycarbonate AK HUTU. Close-up of mounted LEDs. The BB ready to be chambered is always illuminated by one or more LEDs. Wire harnesses. Choose from mini Tamiya, Deans, JST, or 9v disposable battery connector. I have been installing HUTUs in my AEGs for nearly a year now to great effect. I've used them at night events such as OP: Crucible and got quite a few compliments for it so I figured I'd offer a few to the public. These have two super-bright UV LEDs mounted in such a way that they always illuminate the next round. If you have a clear air nozzle, the chambered round can also be illuminated. They are capable of operating in all conditions, even underwater. The LEDs do not cause any feeding problems and will last indefinitely and are controlled by a micro-voltage regulator assembly so you can attach practically any battery you want up to 11.1v. This is a GREAT way to re-purpose those old NiMH batteries that came with your AEG when you first bought it. Technical Specs: Input voltage: 7.2v to 11.1v Moisture/precipitation/condensation-resistant: Yes Submersible: Yes Each set comes with your choice of wiring harness, the HUTU itself, and all related hardware. Choose from mini Tamiya, Deans, JST, or 9v disposable battery harness. JST harnesses are marked to identify the battery connector since both side have the same JST plug. For M4/M16 users, you must have your AEG rear-wired or you will have to pass the HUTU wiring through the open gap on the lower receiver near the body pin. AK users need to have their AEGs rear-wired. Available in the following configurations: AK Polycarbonate: $24.00 shipped AK Metal: $36.00 shipped M4 Metal: $36.00 shipped All additional wire harnesses are $12.00 each. 5. Sorbothane Pads with Neoprene Impact Faces V2/3 Sorbothane pad and offset version. Like how an airbag works to arrest a person inside a vehicle in the event of a crash, Sorbothane pads work to prevent gearbox fractures and reduce stress, as well as correct the angle of engagement between the sector gear and piston while slightly muffling sound. Each pad is composed of a 3/16” thick stamped Sorbothane disc and an 1/8” thick neoprene disc for a total thickness of 5/16”, perfect or nearly perfect for most angle of engagement adjustments. Unlike competitors’ Sorbothane pads, these pads come with bonded neoprene impact faces as a standard feature to prevent piston head ports from disintegrating the bare Sorbothane. Prevent this from happening in the first place: Price: $4.00 each shipped 6. M-Series Full Stock Washer M-Series Full Stock Washer M-Series Full Stock Washer installed on lower receiver More of a conceptual exercise than anything else, the M-Series Full Stock Washer is made to fill the space between a full M16 stock and the lower receiver. When you forget to reinstall yours and lose it or when your full stock kit lacks this piece, now you have a source of readily-available replacements. Price: $6.00 each shipped 7. Angle of Engagement Adjustment Washers Set of 4 Angle of Engagement Adjustment Washers Much like how gears can be shimmed to be more efficient, pistons can be shimmed as well. Adjusting the angle of engagement between the first sector gear tooth and first piston tooth alleviates stress and yields a longer-lasting piston. These adjustment washers are made of super-low-friction PTFE and are about 0.03” thick. Combined with a 5/16” Sorbothane shock-absorbing pad, 1-4 washers may be needed to perfect the angle of engagement. WARNING: Take precaution when adjusting the angle of engagement between the piston and sector gear. Complete removal of the second piston tooth is required and partial removal of the third tooth is usually necessary. Lightening of the piston assembly, also known as “Swiss-cheesing”, is highly recommended in AEGs with high cyclic rates. Price: $6.50 shipped per each 4-pack 8. Standard Motor Connectors (now with locking detents) Standard motor connectors. Tin-plated brass motor connectors sold in packs of 4 with a length of heat shrink tubing for the user to cut to length and install accordingly. The motor wires will lay across the brush hoods and connect to the motor terminals from the top. These have been revised as of 11/16/2012 to have locking detents that better secure them to motor tabs. Price: $2.70 shipped per each 4-pack 9. Right-Angle Motor Connectors Right-angle motor connectors. Brass motor connectors sold in packs of 4 with a length of heat shrink tubing for the user to cut to length and install accordingly. The motor wires will connect to the motor terminals from the sides, creating more space for the motor end grip to properly seat against the endbell. Price: $2.90 shipped per each 4-pack SERVICES: I offer all sorts of airsmithing services from parts installation and tuning to complete gun building. To request a quote for your specific needs, send me a PM. A la carte services (return shipping not included): R-hop/IR-hop installation and tuning: $40.00 plus cost of patch ER-hop/IER-hop installation and tuning: $65.00 plus cost of patch Barrel window and hopup unit modification for ER-hop systems: $45.00 Complete rewiring (can be applied to MOSFET wiring): $30.00 Cold weather preparation for Marui-spec gearboxes: $40.00 All other services are handled on a case-by-case basis.
