So you just built a larger-sized AR chambered in either .308 Winchester, 6.5 Creedmoor, or even .243 Winchester, but you know what? Unless you want it to be nothing more than a replica or a life-sized prop, you're gonna need to install the guts too, to get it to function. The "guts" of the upper assembly (upper half) are simple: you need a bolt carrier group to slam into your upper from behind.

This is the BCG you need for you larger-sized AR. Each one has been magnetic particle-inspected (MPI tested) and comes in a parkerized / black nitride finish to match the rest of your rifle. It's made from 9310 steel and has a staked gas key, so you can keep chucking rounds downrange without worrying about your insides rattling loose. See below for more info.
