Life saver

Got me out of a pinch. So if you get A Durkin Tactical lower with the screw in bolt catch, this works in that lower as well. I somehow lost mine and bought this just to try and see if it would work, thank goodness it worked perfectly.

Bolt catch screw

I used this to secure a bolt catch on an 80 percent lower that had the threaded bolt catch instead of a pinned one. I wasn't sure if it would work but it did and was very pleased. I bought three so I would have them on hand in case I ever came across any more lowers that had the threaded bolt catch. Great product! Fit and functioned flawlessly!

Works perfectly

Does it's job. Solid design. Installs easily and correctly. Made well. Easy to install and remove if necessary. Much nicer design than the pins.

It does its thing well

The highest compliment I can pay it is that I dont even think about it. It just does what its supposed to do.

Nice feature for m4e1.

Nice fit and ease to install strong bolt catch pin very good quality.
