This is a set of spare O-rings for Novritsch SP1, SSP2 & SSP5 V2 magazines. They are the perfect replacement parts for magazines that are leaking gas. Become a maintenance master and fix your leaky mags, rather than spending extra on new ones. Should your magazine spring a leak, a spare set of O-Rings is always handy. 

Fix your Novritsch magazines so they're skirmish-ready, or have some spare parts should the worst scenario occur. The Novritsch SSP2 O-Ring Set gives your magazines a second chance at fighting!

If you love your Novritsch pistols and want to keep them shooting pristine, keeping a spare Novritsch SSP1/SSP5 Nozzle can't hurt! This polymer loading nozzle is compatible with Novritsch SSP1/SSP5 GBB pistols and is a fantastic part to have lying around just in case a catastrophe strikes, especially if you often find yourself relying on your sidearm. If you're very attached to your Novritsch SSP1/SSP5 pistols and don't ever want them to sit around awaiting spare parts, grab this to put your mind at ease and get your Novritsch pistols back on the battlefield!

If you are working on your dream AAP-01 build you will want it to be performing to its maximum until the end of time. An upgraded hammer is a great way to improve your AAP-01's longevity and its resistance to wear. The CowCow SS Hammer Set is constructed from CNC machined alloy with a stainless steel finish and is highly polished for smooth operation with minimal friction.

If you want your AAP-01 GBB to be running at its absolute best an enhanced nozzle would be a great choice to get the most out of this impressive platform. The CowCow Enhanced Plastic Nozzle Set includes an enhanced nozzle, nozzle valve, valve lock pin, valve spring and enhanced piston head, and when installed these parts should improve the shot to shot consistency, provide smoother cycling performance and improve the rate of fire of the AAP-01 Airsoft GBB.

The CowCow Trident Sear spring is designed to replace your original sear spring, and features revised contact surfaces which have been narrowed to prevent excessive friction with other parts. If you are building a high speed Hi-capa or 1911, this is perfect for the job!

If you are looking for reliable long term performance from your EU series GBB pistol, AAP-01 Assassin or Umarex/VFC pattern Glock GBB pistol, CowCow are here to provide! This replacement fire pin lock is constructed from stainless steel using precise CNC machining and is polished using MAF polishing technology for smoother function with less friction. The stainless steel construction of this part prevents warping under heavy use, and guarantees reliable long term performance, assuming the rest of your pistol is working fine!

Is your AAP-01 not fast enough? The CowCow Aluminium Buffer for AAP-01 is designed to satisfy even the most ravenous appetite for speed! This set includes two recoil rod spacers which are CNC machined from 6061 aluminium to provide a great balance between strength, precision and low weight. Adding one or two of the spacers to your guide rod will reduce the length of travel of the AAP-01 bolt and speed up the already impressive cyclic rate of the AAP-01 in both semi-auto and fully automatic fire.

If you are after an improvement in recoil force and cyclic rate from your Airsoft AAP-01 GBB pistol, an uprated recoil spring is a great way to get there! The 150% Recoil Spring from CowCow provides an increase in strength over the original recoil spring installed into the AAP-01 and should improve the rate of fire and provide a snappier bolt speed with a slight increase in recoil.

The Competition Recoil Buffer Module from CowCow is designed to shorten the travel of the slide of your pistol, increasing its cyclic rate. The set includes 8 recoil buffer pads of varying hardness which can be stacked in various combinations to fine tune your pistol for optimum speed.

So you have yourself a snappy pistol, but you want MORE speed? If you say so! The RS1 recoil spring from CowCow replaces your original recoil spring and will increase the speed at which your slide returns to battery, increasing the cyclic rate. Perfect for those who need that extra bit of speed!

If you have a pile of leaky mags, now is the time to fix them up! The WADSN Gas Magazine O-ring Repair Set includes 10 O-rings of 7 different sizes, designed to replace the O-rings of the knocker valve and fill valve in most Airsoft gas magazines. The set is supplied in a clear polymer organiser case to keep everything neat and includes a set of polymer installation tweezers to make installation without damaging the O-rings considerably easier. If you have a lot of leaky mags gathering dust, this set is the key to giving them a new lease of life!

If you are after an improvement in FPS and recoil force from your Airsoft AAP-01 GBB pistol, an uprated nozzle spring is a great way to get there! The 200% Nozzle Spring from CowCow provides double the strength of the original nozzle spring installed into the AAP-01 and should improve FPS and provide a snappier cyclic rate with a slight increase in recoil.

If you want to add a touch of style to your plain jane EU series or AAP-01 GBB pistol, the CowCow Tactical Trigger is a great way to set your pistol out from the crowd. This trigger is available in three colour options; matt black for a more tactical look, silver for a touch of class, or gold for those after a "loud and proud" look. 

Each colour option includes even more options when it comes to the trigger safety extension, as each set comes with a red, gold and black extension piece to choose from. This trigger is a partially flat design for additional speed but also includes a finger ledge to prevent your spritely trigger finger from slipping off. This trigger is designed for the Tokyo Marui EU series of GBB pistols and is also compatible with the Action Army AAP-01 and AAP-01C, but may also fit some other EU pistols based on the TM design.

An upgraded hammer is a great foundation to any upgraded AAP-01 build, especially if you are an HPA user! The CowCow SS Hammer is CNC machined from strengthened alloy with a stainless steel finish, and MAF polishing technology is applied to its exterior surfaces to reduce friction between parts and ensure smooth operation of the pistol.

A high quality replacement Hop up rubber, made to 70 degrees of hardness, and designed for VSRs, as well as KJW and WE Airsoft designs.

If you are building out your dream Airsoft Hi-capa GBB pistol, the CowCow Stainless Steel hammer strut would be a great addition if you require an improved trigger feel and better mechanical engagement. This part is constructed from stainless steel with a titanium coating to prevent corrosion and warping. When installed into your TM based Hi-capa or 1911 GBB this part should help improve shot to shot consistency and provide longevity far beyond the original parts.

If you are building out your AAP-01 to push its performance up to new levels, make sure you toughen it up for the long term while you are at it! With that in mind, the AAP-01 Selector Plate from CowCow Technologies provides a replacement for the original selector plate which is far stronger than the original alloy piece and is precisely machined from aluminium using CNC technology for precise engagement for a lifetime of heavy use. 

If you have an Army Armament 1911 GBB with a broken nozzle you are in luck! The Army Armament Nozzle for 1911 GBB Pistol is a replacement original part designed for the Army Armament 1911 GBB series, including the R26, R28, R31 and R32 pistols. This nozzle may also work with TM-compatible 1911 pistols from other brands, but as always we only recommend brand mixing for the experts as this may require fine-tuning and modification.

An ideal replacement for any low powered or leaking CO2 pistols and revolvers produced by ASG.

The kit can be dropped into any WE,  Tokyo Marui, or VFC EU-Series gas blowback Airsoft pistol for instant results. The set includes an alloy Hop-Up unit, 60 Degree hop-up rubber and Crazy Jet Inner barrel for high performance and improved accuracy. This is perfect for those who are looking to upgrade their pistol with minimum effort.

If you want to upgrade your Umarex Glock and build a sleeper of a long ranged pistol setup, this is the HOP-up unit you need! The Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is compatible with the Umarex/VFC Glock 17, Glock 19, Glock 19X and Glock 45 GBB pistols and is constructed from alloy for improved strength. The unit is supplied with two HOP-up arms with one pre-installed, giving you a spare to keep handy or modify for some experimental HOP-up setups. 

The tolerances of this unit are far more precise than the original, offering better air seal and gas efficiency, translating into better effect on target and better consistency. If you want to shock the enemy by landing a hit with your pistol at long range, the Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is the key!

If you have a magazine which leaks from the fill valve, or your mag is a bit old and the valve has taken a hammering over the years, a replacement valve is the way to go. This Specna Arms valve replaces the fill valve in your magazine with a nice fresh one, complete with an O-ring to ensure there are no leaks! This valve will require a valve key to install.

An absolute monster of an upgrade to make to your weapon. The external surface is ribbed to keep your inner barrel more stable inside your hop up unit with next to no play at all after you have fully re-assembled your Airsoft weapon.

If you have hammer issues with your Army Armament Hi-Capa, this should help! The Hammer and Strut for Hi-Capa GBB Pistols from Army Armament is constructed from Aluminium and an original replacement part for the Army Armament Hi-Capa GBB series, including the R501, R504, R603, R608, R609 and potentially others. The set includes both the hammer and hammer strut and should be compatible with most TM clone Hi-Capa pistols, though it may need mods for anything other than Army Armament 'Capas. 

This hammer is an original replacement part for the Army Armament R601 JW3 GBB pistol but may also fit other Army Armaments Hi-capa based GBB pistols. A hammer is a great spare to have in the tool kit if you use your JW3 pistol heavily, as over time these tend to wear out due to the repeated impacts on the hammer with every shot. Having a spare hammer on hand for worst-case scenarios can help avoid disappointment and potentially a long wait for replacement parts and allow you to have your pistol back up and running quickly for its next outing.

The Army Armament Green Gas Valve Kit for AA Hi-capa & 1911 GBB is what you need if your magazine leaks from the fill valve or knocker valve. The set includes replacements for both, complete with pre-installed rubber O-rings. 

This set should be suitable for most Hi-capa and 1911 GBB pistol magazines but is specifically designed for Army Armament R26, R27, R28, R29, R31, R32, R45, R501, R601, R603 & R604 magazines. We recommend a valve key for easy installation. Breath new life into your pistol or save money fixing an old mag instead of replacing it!
