Have purchased several. - Battle Arms Development AR-15 Cast Enhanced Magazine Catch

After many years of building, I have failed to appreciate the mil spec mag catch that comes in most lower parts kits. I've had some break, be broken out of the box, rust, rough threading, and so on. Plus, if you like using billet mag release buttons that dont thread all the way through, the standard mil spec will stick out pretty far. These BAD Enhanced Catch's are shorter, smoother, and machined better. My only gripe is the inconsistency with the finish on some of them, but it's still a far better option in my opinion. Worth the money.
