The bolt carrier group is the most critical part of a rifle, and if you are building an AR-15, you should check out the Rise Armament RA-1010 AR-15 Low Mass Bolt Carrier Group.

Lightweight Skeletonized Design

This lightweight bolt carrier group is skeletonized and can significantly decrease the perceived recoil of your rifle by reducing the reciprocating mass in the receiver. You can also pair this bolt carrier with a lighter buffer tube spring for a higher rate of the rifle, and faster follow-up shots. Moreover, a lighter bolt carrier group like the RA-1010 by rising Armament can also help you improve your accuracy. Decreasing the recoil impulse makes it easier for you to keep your sights on target and land quick and accurate shots.

Individually Inspected

The Rise Armament RA-1010 Low Mass Bolt Carrier Group is manufactured in the USA, with high levels of precision and attention. Each piece is individually inspected and MPI tested for durability and performance. All the components in this BCG are made from high-quality steel and have a Bath Nitride or Nickel Boron finish to ensure longevity and ease of maintenance and cleaning.

So, if you are looking to build a competition rifle or simply want a fast and smooth shooting AR-15, the Rise Armament RA-1010 BCG is a fantastic option.
