Looks sharp!

Nicely done. My MK12 Mod1-esque build shoots the lights out. I really enjoy shooting it and I love the look.

Nicely done X. Nicely done indeed. Hey. Speaking of the PIF. You remember those tactical gloves - the rappelling ones? Well my son wears them now when we shoot and train. He’s grown into them over the past what…3 years?? Anyway I remember the deal back when we did a PIF/E&E deal on those. I still appreciate it…

But nice build and solid components. I think you’re going to be happy with the performance on your BA barrel. I ran the same one on my SPR and it was VERY accurate.

Be sure to post up a range report. I’d like to see if you get similar results as I did.

Well done bro.

Oh yeah, I remember the gloves. I was scoffed at for trying to give them away on another forum because of the cuts on the cuffs. Crazy.

I’ve been plenty pleased with my other BA barrels and have no doubt this one will be just as good. My guns are usually more accurate than I am.

Nice… I was lazy on mine I just purchased a complete upper from Bravo.

18" to 20" rifle gassed guns make me all tingly in the giblets. Nicely done, post some range pics when you get a chance.

I am getting ready to start another Mk 12 Mod 1 and O build, just need to get all of the hard to find parts, especially the ARMS 38 rail.

Rifle length AR’s are really growing on me, nice work.

This thread is old but at least it is this year. I built a 20" Rifle with a Colt 1/9 HB and a YHM FF handguard. Has a NIKON 3-12 BDC AR scope. It shoots great out to 550 yards even with factory ammo. I have been wanting to build a similar with that same BA 18" SPR barrel. How does that barrel shoot?

Hey there! Was scrolling through and saw this post, and since I have this barrel, I thought I’d answer.

I regularly shoot mine out to 840 yards, hitting a 12" target or a man sized target. It’s a fantastic barrel, and is well worth the money. I think i got mine on sale for like… $120?
