Another important factor to consider is the type of bolt. The bolt is the part of the BCG that strikes the primer of the round and engages the barrel’s rifling to spin the round. The most common types of bolts available are mil-spec or full-auto, though some companies offer specialty bolts such as low-mass bolts or adjustable gas keys for more specialized applications.
When shopping for a BCG, it’s important to consider the gas system of your rifle. If you have a short-stroke gas system, you will need a low-mass bolt carrier group. Finally, it’s important to consider the quality of the BCG you’re purchasing. Check out customer reviews and ratings, and make sure the BCG you choose is from a reputable manufacturer.
