Ironmen Intimidator, Compressed air, Evo hopper and a Smart Parts AA barrel
Slots in the front so it wont mess up your ball detents.
The spring and ball bearing that hold the pin in the bolt popped out.
The main reason I bought this bolt was to keep the wear and tear off of my ball detents. It does a great job with that.
It would be a fine bolt if not for the problem with the pin. Apparently this is not an isolated case, since other reviewers also posted about it happening. This instantly renders the bolt useless. I have it temporarily fixed by shimming it with some plastic, but I am very disappointed.
Not worth anythign more than $10, I feel like I got ripped off. The bolt itself is well made, but if just one component is poorly made, it makes the whole thing poorly made.
