Gas Blowback: Airsoft O Rings & Springs

Looking for more recoil from your EU series GBB pistol? Installing a stronger hammer spring should do the trick! This 140% Hammer Spring from CowCow replaces the original hammer spring in your Tokyo Marui based EU series pistol and provides additional force for each hammer strike, releasing more gas and providing higher FPS and improved recoil and slide speed! This part is constructed from high strength spring steel and is hard-coated to prevent corrosion.

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

An upgrade or replacement stock sear spring for gas blowback pistols. The spring is made of robust steel and therefore will hold its shape better than stock springs, which is perfect for keeping your trigger action to be short and crisp. Due to the springs high tolerance, there would be no need to shave it down to fit in your grip.

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!

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!

The CowCow Technologies Enhanced Rotor Spring replaces your original rotor spring with a high strength part with a hard coating to prevent corrosion from developing over time. This spring is only compatible with the Umarex/VFC pattern Glock GBB series and should help extend the lifespan of your Airsoft pistol.

The Supplemental O-ring set from CowCow is designed to work with their B01 blowback housing. The O-rings are constructed from oil-resistant rubber, ensuring they will not swell when exposed to lubricants used in Airsoft GBB pistols. Included in the set are 3 O-rings measuring 9.5x2mm, 9x1.9mm, and 9x2mm.

If you are getting inconsistent performance from your Hi-capa, it is likely that your valve knocker spring has been worn out. Fear not, Airsoft Masterpiece has provided a replacement spring set which will keep your Hi-capa running smoothly in the long term! The set includes two springs, either of which can be installed into a TM Hi-capa or clone.

If you are fixing up your Hi-capa or 1911 you might need one of these! The Slide Stop/Safety Spring and Plunger includes the dual purpose slide stop/safety spring and the plunger for each, making it the perfect replacement set for those who have lost or damaged these parts. All components in this set are constructed from steel, and are designed to fit the Army Armament 1911 and Hi-capa GBB pistols but may fit others based on the Tokyo Marui internal design. 

A silicone rubber seal designed to fit on the bottom of your Hi Capa magazine internally, to replace old and work out seals and reduce leaks. With a properly fit and lubricated seal you should never experience a leak again, just ensure you coat the seal in silicone based lubricant prior to fitting it, and be gentle! These things may snap under too much tension.

If you have a leaky M887x series shotgun this is what you will need to fix it. Replacement complete O-ring set, useful to repair your old unloved Shotgun or refresh your well loved Shotgun.
