We carry Bolt Carrier Groups BCGs, stripped bolts and the small parts which make up each BCG. If you’re building a new AR rifle, or are simply trying to repair an older BCG, you’ve come to the right place. The Bolt Carrier Group is the heart of your AR15 or AR10, so shop from our wide selection of options in finishes, colors, and calibers. Popular brands like JP Enterprises, Faxon Firearms and CMMG offer high quality BCGs that will go the distance on your modern sporting rifle.
You can also browse models that have been rated as best by our informed customers. Our BCG collection is available with Phosphate, NP3, Melonite, and Nitride coatings as well as eye-catching Nickel Boron. All these finishes assure corrosion resistance and reliable functioning. Choosing a Bolt Carrier Group for your next rifle build doesn’t have to be a chore. We cover the best-in-class bolt carrier groups for mil-spec, low-mass, slick coatings, exotic materials, and more.
While you can purchase a bolt carrier group for your AR-15 fully assembled, you can also buy the parts you need and put it together yourself. While there are many ways to improve a stock AR-15, upgrading your bolt carrier group is one of the bigger wins for taking your AR to the next level. It’s essential to consider what you want out of your gun and the areas that you think need improvements. How you choose to upgrade it will determine what sort of performance boost you experience.
