Bolt Carrier Group

AR15 BCG

The AR15 BCG (Bolt Carrier Group) is the heart of every AR Rifle, and it’s particularly important to have a well built BCG to mitigate any chance of malfunction.  Monmouth USA offers Bolt Carrier Groups by top brands such as Toolcraft, Aero Precision, Anderson Manufacturing, and a lightweight options by JP Rifles, and Faxon Firearms.  There are several finishing options to include phosphate, black nitride, or nickel boron coating.  All brands carried by Monmouth USA have properly staked gas keys and come with unconditional warranties should there ever be an issue with quality or function.  Our favorite is the buttery smooth Toolcraft BCG!  If you need assistance in the selection of an AR15 BCG for your next AR build, send us an email at support@monmouthreloading.com
