Welcome to Mounts Plus and our selection of AR15 Bolt Carrier Groups (BCGs). The bolt carrier group is one of the most important components of any AR15 build, as it houses the bolt and helps to ensure smooth and reliable cycling of the action.

When it comes to choosing the best bolt carrier group for your AR15, there are a few key factors to consider. One of the most important is the material that the BCG is made from. Many high-quality BCGs are made from durable materials such as stainless steel or titanium, which can help to extend the lifespan of the component.

Another factor to consider is the finish of the BCG. Some finishes, such as nitride or phosphate, are more resistant to wear and corrosion than others. This is especially important if you plan on using your AR15 in demanding environments, as a well-finished BCG can help to ensure reliable operation even in the most challenging conditions.

At Mounts Plus, we carry a wide range of AR15 bolt carrier groups to choose from. We stand behind the quality of our products, and we're confident that you'll find the perfect bolt carrier group for your AR15 build here at Mounts Plus.
