Have you ever shot an AR-15 that runs so sweet you hardly even know it fired? It's not magic. It is a balance of the rights parts working together. One of the parts necessary for this to happen is a low mass bolt carrier group. Now you can get one here at Wing Tactical. I'm talking about a quality low mass BCG by Odin Works.

Off To The Races

The term race gun refers to a firearm that runs fast and smooth with little recoil or muzzle rise. Of course, to make that happen, you need a little more than a low mass bolt carrier group. To get your race gun to run it needs tuning. That means you combine a low mass BCG, an adjustable gas block, a lighter buffer, and the appropriate load. However, when you get it right, it's worth it. Not only is your gun more fun to shoot. These changes also cause less stress on your weapon and your shoulder.

Get A Free Target Rifle

Okay, maybe not for free, but for a fraction of what a new gun would cost. Once you have an adjustable gas block on your AR-15, the rest is easy. You can switch out the low mass bolt carrier group and buffer literally in minutes. Therefore, you can use the same gun for hunting, self-defense, and have a soft-shooting target rifle for fun.

Consequently, more trigger time can make you a better shooter. Better yet, the more you use the same weapon, the smoother and more efficient you get. The Odin Works low mass BCG is the perfect candidate for this project.
