If I wanted to build a basic budget friendly build with this what would you suggest?
Bob R on Sep 2, 2019
BEST ANSWER: If you live in a SBR friendly state I recommend you apply for one. Form 1 Individual applications are taking about a month for approval. But if you're doing a pistol build then dont worry about that. Reliability between a 10.5" and 11.5" upper is actually significant. In favor of the 11.5" that is.
Is the barrel an FN CHF barrel? I'm seeing them for 10.5 but not 11.5!
Erich P on Sep 13, 2019
I don't understand the special warning about purchase and ownership of uppers with a barrel length of less than 16". Isn't that the same as buying a pistol?
d r on Sep 5, 2019
BEST ANSWER: If you have one of these in your possession you want to either have a lower receiver purchased as a pistol or a stripped lower that was listed on the 4473 as ‘other’. If you have an upper with a barrel less than 16” and only a rifle lower you can be charged with constructive possession of a SBR.
Which rear BUIS would be compatible with the F-Marked gas sight base? Thanks

Can't Go Wrong
The 11.5 is imo the perfect barrel for an AR pistol. There is a substantial ballistic advantage over the 10.5. The classic nitride is a great basis for my get-home gun. I prefer a fixed front sight on a gun I may have to stake my life on. I did make some upgrades to suit my needs but this upper is a solid foundation.

Way better than 10.5
Recommend! Smooth shooting and repliable. Zero malfunctions in 2k plus rounds of the cheapest ammo I can find (usually wolf). I have since chopped the front sight and added a Troy battle rail.

Great SBR upper...
Bought one of these as a secondary upper for a registered SBR lower. I threw on a carry handle w/ micro red dot, swapped out the factory hand guards with CAR15 hand guards and finished up the upgrades with a Strike Industries Extended Charging Handle Latch. What a sexy upper. It has that M733 appeal with some up to date features. Definitely one of my favorite SBR uppers.
It eats brass and steel cased ammo without any issues. Even my own .223 reloads that run more on the light side.
If you're not sure about the reliability of a 10.5" upper and don't want to deal with buffer weights and buffer spring strengths to make it run right, then the 11.5" barrel is the way to go.
