AR's with 7.5 & 10.5 inch barrels?

Postby Stoble » Fri Sep 07, 2018 8:59 pm

Recently been learning about these guns. For those shooting for fun under 200+ yds. they seem interesting. Anyone own one? The 10.5 seems the most useful to me.

I have a Sig516 pistol with the 10.5" barrel. I bought it as a travel gun that I could manipulate from the cab of my truck if need be. The 7.5" would have made it even easier, but the problem with that is that when you get below 10" you lose so much velocity that you essentially at that point just have a .22 Magnum. Now, .22 Magnum is respectable, but I don't want it for a primary defense gun.

I’ve got a custom 300 blackout with an 11.5 inch barrel and it is an absolute blast to shoot. Don’t think I’d use it for a primary defensive weapon though. Like Nate said the short barrel just kills the velocity.

I read in an article that the 10.5 barrel would lose about 400 fps in 5.56 and another person said their 7.62 ran 2000 fps with a 10.5. At my distances this would not be a problem. Has the shorter sight radius been a negative? Just under 6 inches from a 16 inch barrel.

10.5 probably the better choice unless your going to be running it suppressed. otherwise the concussion and muzzle blast will become quite unpleasant.

both should be effective at distances under 200 yards if you can do your part.
