Step up to E.R. Shaw's match-grade stainless barrel here, with a tighter 1:7 twist and heavier HBAR profile built for accuracy over volume. Reviewers on this exact build are reporting sub-MOA groups at 50 yards with handloads, which tracks with what a stainless match barrel is supposed to deliver over a standard chrome moly. Same 15" MLOK real estate as the medium-profile build, but you're paying for barrel precision, not rail length.

300 Upper Shaw
More than satisfied. Fast shipping and excellent product. Will be using this soon for varmints and next year for deer hunting. Crazy accurate too with 1/2" groups.

300BO upper
The Shaw barrel was a good choice since I'm getting tight groups. 1/2 inch at 50 yards so far. Ambi handle is nice too!

Got excellent groups with cheap Hornady Black 110 gr. Can't wait to really dial it in with some sub handloads. No issues suppressed either.
