Gas Blowback Internal Parts

Upgrade your GBB Hi-Capa and facilitate insane cycling speed with the EDGE Ultra Light Aluminium Blowback Housing. Perfect for either competition shooting or for you speedsofters out there, this blowback housing is incredibly light, weighing approximately 17g, complete with its piston and O-ring.

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

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.

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 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!

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.

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 is designed to improve the air seal performance and gas efficiency of the AAP-01, the result of which should be an increase in rate of fire and cyclic speed, with less wasted gas per shot. The set includes an enhanced loading nozzle for the AAP-01 GBB and the nozzle valve lock pin.
