.45 ACP Enhanced Bolt Carrier Group - Black Nitride

The NBS Enhanced 45 Bolt assembly is designed for AR-15 style rifles chambered for .45 ACP with a direct blowback system. This bolt is weighted with Tungsten weights adding up to 16 ounces total in order to eliminate the need for heavy buffers. This added weight is necessary for blowback firearms because it helps to delay the bolt from moving rearward just long enough for pressures to reach a safe level. Depending on your setup, it can also reduce felt recoil and reduce the amount of bolt bounce. It features a full size .308 style extractor that can be removed for cleaning. Compatible with all types of hammers, this .45 ACP bolt is a great option for your next pistol caliber carbine build.Features: Compatible with Glock magazines Complete bolt for blowback systems Full size .308 type extractor Tungsten weighted Works with all types of hammers 16 ounces
