What do you mean by "build"? Buying a kit or sourcing parts individually?I never had any thoughts of wanting an AR pistol, but with all of the attention the brace rule litigation has brought about, I decided to build one. I procured an SB3 brace and I’ve decided to just stick with .556 NATO caliber (or .223 Wylde). So my questions are mostly, what barrel length, twist rate and are there any tricks or things I should know, or avoid, what works best. All input is welcomed.
Thanks
Initially I wanted to actually build it, but I can't build it nearly as "cost effective" as a kit. Assuming I can find exactly what I want. I've bought two PSA AR rifle complete uppers that have been great. So I'm open to a kit if I can find what I want.What do you mean by "build"? Buying a kit or sourcing parts individually?
I bought a few build kits and have been happy with their quality and performance for the low price tags.
.300 Blackout is a good round for a pistol in the 8” plus range. It’s not as loud or has as much pressure/recoil as a 5.56, has variety of effective loads available, and works with a lighter buffer. Ammo does cost more.Initially I wanted to actually build it, but I can't build it nearly as "cost effective" as a kit. Assuming I can find exactly what I want.

That's good information. That's why I love this forum. The wealth of knowledge and experience available and the members here are happy to pass it on..300blk is expensive and rare. If you aren't already set up to reload, or have a .30 caliber suppressor, it's a big investment.
5.56 isn't the best out of >14.5" barrels, but even the cheapest m193 55gr ammo will still yaw and fragment out past 50 yards out of a 10.3" barrel. Better rounds (m855a1, mk262, mk318, gold dot, TAP, fusion, etc) will perform better.
11.5" is a good length. Velocity is already a non-issue, the real benefit with longer barrels is the increase in parts life, as shorter barrels will break bolts, extractors, and cam pins.
It's certainly more rare than the single highest volume centerfire rifle cartridge sold. It's certainly more rare whenever there's a panic.I wouldn’t call 300BO rare by any means. You can walk into virtually any Academy and find it on the shelf. It will cost more than 223, but it will be there.
Using Ammoseek as a source, brass cased 223 can be readily had for 42 cents/rd plus shipping, while 300BO is at 58 cents/rd plus shipping. I wouldn’t call that exceedingly expensive.
@Coon if you do decide to go 300BO, don’t be afraid to go a bit shorter than 10.5”
If you’ll notice in the chart posted on page one, a 9” 300 can have as much energy as a 14.5” 223.
Of course it would also depend on how far out you want to try and reach critters as well. A 9” 300 is probably not going to be a great 200 yard rig.
“More rare” is obviously subjective.It's certainly more rare than the single highest volume centerfire rifle cartridge sold. It's certainly more rare whenever there's a panic.
That 58 cpr .300 is ammo inc, which if you factor in all the duds you'll have will put you in the high 70 cents per round

223 is more rare than 22LR, I guess OP should not consider it either.
There are multiple manufacturers at that price point.

Don't have to worry about things selling out if you're already stocked.223/556 will sell out first in a panic over 300BO.
Or just don't waste ammo just to go shooting.
Yeah we po folk gotta save somewhere may as well save ammo. I've never needed to spend extra $$ during the disturbed events.
