Can be installed on any standard centerfire upper as well to protect bolt carrier cover. Slide over front and rear take-down pins, then secure it with the two cotter-style push pins.

Great idea; great product

This is a necessity if you have multiple uppers, especially if one of them is a .22LR. Works like a charm and super affordable.
Brilliant idea.

All interchangeable uppers are now dust and dirt free. No more sliding the bolt carrier back in. Got them in black and OD green like the receivers these go on. Kudos to BDM.
