As the title states rented the gun and it would not cycle the crappy Remington birdshot they had. I was expecting it to work solely based off the nutfancy review but then again supposedly it was brand-new and I had the gold/bronze universal piston in the one he reviews has the two pistons. Just really bummed out because I want to buy that shotgun really bad just don't know now. Does the gold piston suck or what ? When he reviews it he's using cheap Walmart federal 1 1/8 oz and it eats it up and goes as far to say it's a pump reliable autoloading shotgun so I figured it would work best not. Thoughts ?? Give another try ?
