The short story is this – it doesn’t matter as much as you might think.Best AR15 Bolt Carrier Ammo

Standard phosphate finished BCGs have been getting the job done for as long as the AR15 has been around.

In the video below, the Military Arms Channel fires over 7000 rounds through a BCM AR15 without cleaning or added lubrication and without a stoppage. A standard phosphate BCG is used for the test.One benefit of using a full auto BCG is that it will usually weigh about 1 oz. more than a semi auto BCG. This extra weight can sometimes have a positive effect on reliability, depending on the configuration of your rifle. It is the equivalent of going to a heavier buffer i.e. from a carbine buffer to an H buffer, or an H buffer to an H2 buffer.

There are two main kinds of AR15 bolt carrier groups – semi auto and full auto.

A full auto BCG does not turn your AR15 into a machine gun. In fact, most AR15s sold today actually come with a “full auto” BCG and there are no legal restrictions against using a full auto BCG.

The only difference between the two is the shape of the carrier. On a full auto carrier the rear lug is larger so it can trip the auto sear on a full auto rifle. It has no function in a semi auto AR15.Whether you need ammunition for target practice, hunting purposes or defensive measures, there is plenty of ammo for sale at Academy from the most popular brands like Federal, Winchester and more.
