AR15 Bolt Carrier Groups

The heart of your rifle. The bolt carrier group is one the most important parts in your AR15 modern sporting rifle. Containing the bolt, the firing pin, extractor and various other small parts, the bolt carrier group must be maintained in order for your rifle to continue running well. Inferior parts can cause premature failures when you need the rifle most. In the middle of a 3-gun match or even during your paid range time is a bad moment to have something stop functioning correctly in your rifle.

We recommend only the using the best parts you can find for replacements or for your AR15 build. Inferior parts end up costing you more money in the long run rather than doing it right the first time, not to mention the frustration that comes from having to put your rifle away when you want to use it, all due to a simple part failure. Buy right the first time and keep spare parts in your kit in case you need them. Some parts like gas rings are considered expendable, so you need to keep a few for replacements as well as keeping an eye on your bolt for worn or cracked lugs. Quality is important if you rely on your rifle. Let us help you find the best bolt carrier group for your AR-15!
