Not all Bolt Carrier Groups are interchangeable and are going to work for any caliber, although some may be able to be used for multiple calibers like the 223/556/300/350. To help make things easier, we at Omega Tactical Distribution have made categories to make finding the right BCG as easy as possible. Take a look at our combo categories as well to find multiple products involving the BCG for a great price!
