Hey, I am trying to brainstorm a jack of all trades rifle. I only have a 22lr bolt action, and I'd like something decently powerful that can fill multiple roles like self defense, home defense, trunk gun, basic hunting, etc.
What I was thinking was a 10.5" AR pistol in .300 blackout. The benefit of that is I can use my conceal carry license with it and keep it in my car. I heard about reliability issues with 223 out of a short barrel like that.
What do you guys think?
UMMMMM, NOT.
Can't imagine where you heard that rumor from.
Somebody must have bought a real crappy short barrel AR pistol from somewhere. I've got an aero precision 5.56 ...10 .5 "...no problems whatsoever.
I think you better do more research.
BCM only sells 11.5" and 12.5" barrels for a reason.
10.5" Mk18s were optimized for use w/ suppressors AND running same overall length as 14.5" M4 carbines...
Most of the rest of the 10.5" since are just copies/clones of that rifle...
Additionally, if you want to go short w/ .223/5.56, you can do so, but they're by far the most reliable w/ a piston system like Adams Arms.
Personally, I'd say 12.5" is ideal for .223/5.56, especially if your defensive rounds are steel ball.
