Easy Upgrade

This catch makes for a very simple improvement. It isn't so big that it gets in the way, but adds just enought to improve the engagement envelope.

Love it!

It does what it is supposed to do and it looks cool too. And at the end of the day, isn't that what we all want? Lol Jokes aside it installed easily. It functions well. And it does seem to make it easier to hit when doing reloads and when locking the bolt back.

Would you recommend this? Yes, I would recommend to a friend

Ignore 1 star.

The 1 star review bought the wrong item and blames the item. Nonsense.

Been running one for years!

Fits great, good extended catch option. Dont listen to the 1 star review. They bought the wrong item and rate this poorly, doesnt make any sense. Anyways, this one works, no issues, good size for gloves.

Won't fit BRN-180

So everyone hates putting that roll pin in and low and behold I get it all put together and the mag catch didn't travel. The bottom flaps prevented the catch from moving. This might fight fine on a standard ar low but not on a BRN-180 lower. It was very frustrating to have to put that pin in several times.

Didn't fit my upper.

My AR-10 upper receiver has an indent that the upper part of the release would set in when the bolt is released. The extension on the bolt catch would not fit into the recess so consequently would not release the bolt. Apparently, I didn't research its application enough.
