Great option for bolt catch - Seekins Precision Enhanced Bolt Catch

This is a cool latch. I used it for a build, and it works better than the stock bolt catch. This catch is extended on the bottom where you would press for the bolt carrier to hold, which makes it easier to do so with your thumb or finger. This will work with most uppers, but some billet uppers will not fit this. I have a billet crosshill technologies upper that does not fit this bolt catch. The paddle style makes it easier to release the bolt. You won't be disappointed in the quality.
