11.5 in a 5.56 is the shortest I like for the following reasons:
- 40% More dwell time compared to a 10.5 - Velocity with M193 |

Those arm braces always remind me of Forrest Gump's leg braces. OP, I've shot everything from 10.5" to 20", and to me the big advantage of a 10.5" barrel is that when you put a silencer on it, it's not terribly long and the amount of rotational force (moment) placed on the rifle by the heavy silencer is less. Since you're not doing a silencer, I would recommend a 12.5" or longer, and avoid muzzle brakes like the plague. |

I absolutely love my CQBR clone. 10.3" 5.56 and never so much as a hiccup performance-wise. As far as buying the 5.56 vs the 300blk, if you're not going to suppress it then 5.56 all the way.

Or.... Have one pistol lower with a Sig brace if it's that big of a deal. That's what I do. I've got a 7.3" CMMG factory pistol that I installed a Sig brace on. Everything else short is an SBR.
OP, if I didn't have any cans I'd probably go 11.5" Seems to be the best compromise SBR barrel length. I'd say 12.5", but if I'm going to pay $200 to cut the barrel, I want to go short. For the record, my two 10.3's and one 10.5 run great. No reliability problems so far can or not. Mostly shooting steel case. One factory DD Mk18 10.3 and two ADCO cut down Colt barrels. Course the 7.3" runs good too. It's just a little loud..... |

Just because they're both exceptional M4/AR15 carbine cartridges doesn't mean that they were designed with the SOLE intent being sub 16" barrels. The M4/AR15 is IMHO the most versatile rifle on the planet. It's effective from a short 10.3" and shorter to a 24"+ barrel. An M4 is typically shorter than 16". However when those rounds were designed the majority of military M4's still had 20" barrels with the number of 14.5"-16" M4s steadily increasing. All that being said, I'd strongly suggest an SBR lower with a 12.5" Grendel Upper and a 12.5" 5.56 Upper.

You probably read that the 12" barrel was determined to be optimal for the unit and its requirements for a carbine. Which translates to as short as they could go while meeting the ballistic requirements. That's far from being the optimal length for an AR15 6.8 in general. The beauty of the AR15 is its versatility, which means there is no one "optimal" configuration. |

10.5 or 11.5 inch 5.56mm. Probably I would go with a BCM BFH 11.5" with KMR 10 rail. If not that, I would opt for a 10.5" CQBR upper with DD Mk18 RIS-2. I predominantly shoot my CQBR upper unsuppressed and really like it.
Other options worth considering are the Colt 6933 (11.5" bbl standard M4-type upper), 6943 (11.5" CHF bbl bbl, monolithic upper) , and 6945 (10.3" CHF bbl, monolithic upper). These are very reasonably priced and have the benefit of being factory made SBRs. |

I contemplated on building an AR Multi Cal SBR very seriously. In the end I decided that for my use, needs, wants and preferences that it was not the way to go.
I built an AR Pistol in 300 Blackout from the ground up with a 10" barrel, KAK Pistol Tube and Sig Brace. Since then I have traveled 3 times to 3 other states on the airlines with no problems. I don't need to get permission to leave my state but above all for Hunting to me it is the perfect setup. Many counties in NC require you to be 8' above the ground when using "Any Centerfire Rifle". Legally you cannot shoot when on the ground on your own two feet. There are no such restrictions when using a shotgun, muzzleloader or handgun. Most of my hunting is in and on the fringes of swampy land and carrying a stand is just a total PITA! Additionally I can "Legally" carry it loaded in my vehicle where a rifle must be unloaded. Don't know how many out there have actually shot one with a Sig Brace but it is very comfortable for me and I am 6"1' 245#. Nope, no SBR headaches for me until I build a bolt gun SBR. |

Without a can having only 1 SBR, 12.5" would be a great choice, ballistically you don't lose much from 14.5 and you still have a compact overall package.
