MM, Do you notice any worthwhile differences between the 10.5" and the 11.5"?

Tyrone, I haven't had any reliability issues with either.
We all know the 11.5 offers more velocity, less blast, and longer dwell time. There is a certain physical and psychological advantage there. Is it enough to matter in the practical employment of either rig? Probably not.
My first pistol upper was the 5.56 in 10.5". I kind of wanted an 11.5", but to build one up from scratch, would have cost probably $450 or so. When I saw the 10.5" from PSA an $229, I said heck with it, I'm going to try this out. I had been eyeing an 11.5" HRT profile barrel that Stag Arms was selling at the time (I don't see them listed anymore).
So My preference was/is 11.5". I kind of 'settled' on a 10.5", and it is just fine. Then added the 11.5" from PSA a few months later when I saw that PSA was now offering an 11.5".

Here's the 10.5" upper from PSA. It's a solid shooter. 100 yards, M855, iron sights, With the Primary Arms 5X prism, Hard to see, but with the CMMG 22LR adaptor,

Those short barrels hurt my ears just to look at them...

They are loud. The 7.62x39 isn't as bad as the 5.56. No experience with the 300BO, but it might be one of the better mannered of the lot, without stepping down to traditional pistol chamberings.
I only shoot outdoors. At an indoor range, they would be quite obnoxious.

M1 carbine is handy - AR pistol is sublime.

I'll tell you guys, I went into the AR pistol the low budget route. Built a lower from a PSA stripped, maybe $175 or so with the SBA3 brace. Then I've accumulated three PSA pistol uppers since then. I've got 10.5" 5.56, 10.5" 7.62x39, and an 11.5" 5.56. These uppers sell for like $229 with BCG and CH. They have all ran trouble free for hundreds of rounds. Yesterday I was out with the 10.5" 7.62x39. Shooting transitions between 25 yards and 50 yards. Then cranked up the rear drum and was plinking away at 500 yards. It's just ridiculous. The 7.62x39, and my 25/50 target setup. Some 11.5" goodness in 5.56, That 7.62 sounds awesome. I went the 5.56 PSA upper and it works but considered the 7.62.
