Daniel Defense. Enough said.


Bought this as a backup to put inside of a Magpul grip. Although I doubt I will ever need it for a Daniel Defense BCG. More than likely, if it gets used, it will be on a friends rifle.

Dropped it in to some aero precision gear and functions like it should. The flat non-polished finish leaves something to be desired but it's an affordably priced reliable name brand product.
