Wilson, Spikes and Lother barrels are what I use on all my builds (one ended up with a DPMS). So out of that list, Wilson has my vote.

Not sure why you aren't considering WOA? My 16" WOA SS Match 1:7 is a laser and others have posted on here that their 18" WOA SPR SS Match barrels are also lasers. Mine is shooting a little over .50" with factory ammo and shoots right around .40" with 77smk handloads. I can shoot 300rds between cleanings with groups staying tight. I also tested with IMI 5.56 77gr OTM MOD 1 ammo and 5 shots at 500yds was sub moa.

just about to purchase an 18 spr barrel for a pseudo-mk12 build myself and decided on WOA. I looked at woa, blackhole and rainier and woa has the best rep from what I have researched.
does the woa shoot worth a shit with a 1-7 if you using light bullets ? thats why i kinda liked the idea of the others with the 1-8 ,iv read they do pretty well even with ball 55gr......

With 62gr XM855 surplus ammo my WOA 1:7 shoots sub .50" at 50yds and 1" at 100. With 55gr XM193 it shoots pretty much the same, maybe a hair worse. I don't shoot XM193 at anything outside 100yds. XM855 I've shot to 400yd without issue and put 1000 through my gun in a Team Tactics training class and it was highly accurate.
WOA sells 1:8 barrels as well if your dead set on it.

You don't need to worry about 55s in a 1 in 7. If you were shooting 40gr thin skinned varmint bullets then you may have something to be concerned about. The lands deform the jackets to the point they come apart in flight. 55gr fmjs are cheap junk, 62s are out of balance too. If you want accuracy use 55gr NBTs, 52gr Sierras or 69gr Sierras. Seems like some of the 64gr bullets are doing really well too.
I can't get any of my guns to shoot .4"-.5" with surplus ammo. How do you guys get such good accuracy out of crummy ammo?

My WOA (1 in 7") 18" varmint barrel that is fluted shoots less than 1/2" at 100 yds with my hunting load of 65 gr. Sierra Game kings and less than that with 69 gr. Match Kings. The group with the dime was shot with the 65 gr. Game Kings.

I have had better overall luck with 8 twist vs 7 twist accuracy wise. However the 7 twist White Oak barrels I've had have always been good and shot MOA or better with everything from 60vmax to 77smk.
I got a Criterion 223wylde when I was building my SPR because it was what I could find and I have been very happy.

I'll be honest, I wouldn't build crap. I'd just buy a complete BCM upper. Good prices right now, and probably some of the best quality around. I have one of their 410 stainless uppers that shoots completely lights out. 410 makes for a good barrel.

WOA makes one of, if not, the best drop in barrel under $400. Beyond that, custom barrels own the targets. I'm waiting on CLE to finish my Douglas 18" barrel that's replacing a Noveske.
I'm happy with my 18" wilson 223 wylde... The skeptics in my precision rifle class got real quiet when the lead started flying... RP brass, 69g SMK, 25.5 H4895, CCI400's
That's whst I'm talking about... You're gonna be real happy about that decision.

Why do you have to use light bullets? What is wrong with heavier bullets?

Read the post by Molon about 1/3-1/2 the way down this page:
1-7 twist with 55 grn ammo - AR15.Com Archive
People say crap like molon is saying but they probably haven't over-spun a bullet or thrown a jacket off. I have and it's frustrating as hell.
A bullet is stable or not. There is no more stable or less stable. There is yaw or there isn't.
Truth is 1:7 is fine for almost anything, but 1:8" is usually more accurate in my experience.
