Rainier Arms Ultramatch Barrels

[Desert_Racer]

I just picked up a 20" Rainier Arms Ultramatch barrel (1:10 twist) for my Mega MA-Ten build a week ago. I've read a few good things about them, and from what I understand they're cut from Shilen blanks.

Does anyone run one of these? If so, what kind of groupings are you getting out of them?

Thanks dudes.

I have an Ultramatch SPR barrel... it's stupidly accurate. I didn't know XM193 could group at 1moa... will be trying to match ammo soon to see what it's capable of... only problem is... i'm not a sub moa shooter.

I've used 'em in 5.56 and 6.8 builds. Very accurate, and shoot well with a variety of ammo. Not finicky at all in my experience.

I have one with the 223 Wylde chamber that I just shot a 1/4" group with. I haven't shot it enough to say how it shoots on average, but that really made my day!

I was shooting reloads with 50 gr V-Max.

Awesome, I'm pretty excited for this build to be done. Now I'm just trying to decide whether I want to get my NF NXS 3.5-15x50 w/ the MLR reticle in FFP or not. Gonna order it next week when I get home off of leave.
