Saagri does a test fire with the Rare Arms AR 15 that is equipped with a Smoke Wolf Suppressor that is a muzzle flash generator... "Test firing the Rare Arms Airsoft AR-15 Shell Ejecting Gas Blowback Rifle with Smoke Wolf Suppressor and HPA Adapter.

I noticed with 12g co2 it would struggle to get a magazine of 30rds cycling and lots of shells would still have a BB. Especially in full auto."
