Put a SlideFire on mine and it rips off 25 rounds and is very easy to control. The funnest rifle on the rack. For about the same money another super fun gun is a Sub2000 with a 31 9mm Glock mag. Enjoy.
Just got back from the NRA range. 175 rounds through the gun with zero issues. The Black Dog 50 round drum worked perfectly too.
Thanks Engage.
