I own a bare bones M&P 10, which currently has a 1:10 twist barrel. Part of the upgrades I want is a better barrel, the one I found looks nice, but utilizes a 1:12 twist rate, how will this influence the ammunition I can shoot? The ammunition I shoot is in the normal 147-180 grain range. What other barrels do you guys recommend? I want something in the 18-20 inch range, I looked at the Spikes barrel initially because I have good experience with their 5.56 barrel. I will link it below.

308 Barrel Kit (18" or 20")

This is our .308 barrel, gas block, and gas tube. This kit was put together for the smoothest shooting .308 barrel you will ever install on your AR-10.

1:10 might stabilize heavy for cartridge projectiles better, but if you aren't going above 180gr, I doubt 1:12 is an issue.

1-12 twist may not be useful from a 16 or 18 barrel. But a bolt rifle with a 24" plus barrel might be what you want a 1-12 twist for when shooting at 1000 yards .

Stay with a 1-10 twist for an AR10

If you check out Criterion Barrels you can find other options like 1-11 20" and chrome lined that tend to be moa and better shooters also . I've been very pleased with there barrels in 223 wylde over some years now .
