Barrel for straight pull AR

[RCP Fab]

I started building a straight pull AR. Why? I don't really know, but I wanted a project to work on and it seemed like a good one considering CT's new laws.

This will be replacing my primary bolt gun for range time, as .223 is readily available at great prices, for now.

I am looking at 20" and 24" barrels, I saw a few 26" ones, but unless there's some mystical reason that I need a 26" barrel, I am going to stick with the 20 and 24" for the options.

Requirements:

Bull barrel, .936"
Stainless
1:7" or 1:8" Twist
I am looking for .223 Wylde, but if not, 5.56
No muzzle threads

I am looking at:

Stag 24" 1:8"

and

Rock River 24" 1:8"

I like the Stag, it's cheaper, and they are 10 minutes from me, but the Rock River meets what I am looking for better.

Rock River says they are not shipping to CT currently, but for a barrel they might.

Went with the stag, figure I can always cut it down.

My question is: why would you use a standard AR barrel? Much better to just get a blank and have it fit to a barrel extension and chambered.

Maybe one day, but for $200, it's hard to beat. I've never even shot a straight pull rifle, I may end up not liking it. Or I may love it and can use this barrel until I decide to get something more custom.
