Everything. Soft face bolt, cobra bolt, full open bolt, stock bolt
Angel lcd wit predator board breakbeam eyes, freak kit, lowpressure everything and my good old back up gun the angel 04 speed.
Never have to worry about roll back and chopping a ball again.
I have alway's been chopping ball's from roll back. Roll back = when a ball goes back into the gun to far exposing a ball overlapping on top. Most angels have this problem. This bolt is worth every penny of my 35$ i spent on it. Just remember to break it in with a stick squeege for about 1000 shots befor using it. I took my angel speed 04 and just turned off the sensi cause you dont need it. With this bolt i havent chopped a ball threw both of my angels in prolly 8,000 balls. If your looking into buying a expensive board and eyes for your gun or just have a angel that chopps every once in awile than buy this board. as you can see i went the wrong way by buying a expensive board and eyes that didnt fix my chopping problem. But then i finally got this bolt and I finally can go and beat up on Timmy's and DM4's bec i can shot about 25 bps with out chopping. unlike befor i got this bolt i could only shoot about 13 bps with some chopps.
If your having chopping problems with your angel or not and want extra saftey without buying a expensive board with eyes then just give this bolt a try. You will love it : )
