A bolt carrier group is essentially the heart of an AR-15 rifle, performing many of its main functions, from firing the round to discharging the spent casing. It also resets the action and chambers the next round, and most impressively, it accomplishes all this largely unseen. Thus, it can be all too easy to overlook its importance—at least compared to the external components of the rifle.
However, serious shooters understand that a quality AR-15 begins with a quality bolt carrier group.
Luth-AR is looking to offer such an option with its new Chrome-Lined .223 Assembled Bolt Carrier Group. Built from 8620 Steel and heat-treated to U.S. military specifications, the group also features a Manganese Phosphate finish with Chrome-Lined Bores.
The full assembly was further crafted with meticulous attention to detail, offering enhanced corrosion resistance and reduced friction to help ensure smooth operation in all conditions. It includes an 8620 Steel Bolt Carrier, Carpenter 158 Steel Bolt Assembly, 4130 Steel Carrier Key, 8740 Steel Firing Pin, 4340 Steel Cam Pin, Firing Pin Retaining Pin, and two Bolt carrier key screws.
The American-made Luth-AR Chrome-Lined .223 Assembled Bolt Carrier Group is fully assembled and ready to be installed. It is available now from the company’s website for $134.99 (Retail sales only).
