This bolt sucks
I used this bolt in my impulse before we hacked the crap out of it and put the dmc frame on it and it almost killed my gun. Somthing about the bolt made my gun cycle way slower and it didn't even do it's job. I had more breaks after I put the bolt in my gun than before with the crappy evil bolt. Save your money, you would be better off with a stock bolt.
