DSA's quality is inconsistent. You can specify a "Austrian STG non-hump" or "traditional metric hump" but you're going to get a very odd fit and moulding marks at the seams.
Penquin use to make two lines (upper and middle quality). The upper was quite nice.
Ironwood makes great wood stocks if you're interested in wood.
You're likely better off getting a Contract foreign stock and replacing some other part if you have a 922r count issue.
