Granted, you finally got your hands on that snazzy new .308 AR carbine and it runs like a dream. You fully expect every trip out to go just as planned, as well it should. However, you should always make it a habit to hope for the best but prepare for the worst. Out of all the internal parts to wear out the fastest, that little old buffer ranks one of the highest on the list. With every round fired that buffer takes a pounding and if it fails, the fun stops right there. Fortunately, if you have an extra Aero Precision .308 buffer in your range bag, the fun can continue.

Heart and Soul

The length of the barrel and your buffer system designates it as a carbine. As such, any old buffer just won’t do, you must have a .308 carbine buffer inside there in order to make things work right. This Aero Precision .308 buffer is specifically designed to mate with your .308 AR carbine wearing a collapsible stock. AR-15 or rifle length buffers won’t do, when you run an .308 AR carbine this is the specific .308 carbine buffer you must have.
