Product Description

The 2A Armament Lightweight Bolt Carrier (LWBCG) is a lightweight carrier solution for those looking to reduce both felt recoil, and the overall weight of the AR-15 pattern rifle. The LWBCG combines a very high quality forward body and an advanced bearing surface aluminum tail to give the shooter a reliable, lightweight, and high quality bolt carrier group. The advanced finned design of the tail section of the LWBCG reduces drag and wear within the receiver extension which increases reliability.

COMPATIBILITY NOTICE: Some 3rd party skeletonized upper receivers have the bore surface compromised that the bolt carrier slides on. 2A Armament does not recommend the use of these upper receivers due to a non-continuous slide surface that can cause binding and cycling-related issues. 2A Armament cannot guarantee flawless fit and function in a 3rd party skeletonized upper receiver
