Because of that, it doesn’t make sense to stick strictly to the M16A1 template. Since then, technology for manufacturing, ammunition, and optics have come a long way. Faxon 18″ Gunner profile barrel, a modern interpretation of the lightweight fighting rifle barrel It was a gunfighter’s rifle, meant to be carried much of the time, and then perform well in a firefight. The M16A1 weighed 6.4 lbs unloaded, which made it exceptionally easy to live with compared to full-powered battle rifles of the time.

In this post, I’m posting a few quality examples of what I’m talking about. The physics of ballistics don’t change just because you went from an AR-15 to a bolt action.Įverything I’ve written here comes from years of reading, competing, training, practicing, and writing articles for this blog and elsewhere.
While I’m focusing on the AR-15 platform in particular, the principles apply to any firearms barrel. This article summarizes just about everything I’ve learned about AR-15 barrels.
