This is a brand new G&G BSG (Bulpup shotgun). Only tested for leaks after installing HPA tapp. HPA tapp (KJW threads) P90S barrel extension that acts as a choke tube, increasing range, but decreasing spread. Includes Green gas valve and all the original packaging. Uses M4 mags and can shoot 5 or 10 rounds at a time! Ask about free shipping! I'm not interested in any trades besides what I have listed in my profile description. I will not part out.
