I have an old Bushmaster XM-15 complete lower that is California 1989 AWB compliant (i.e., A1 stock) purchased back when it was unclear if any kind of AR would be available after the California single-evil ban. It was a panic purchase to get a serial number in on the California assault weapon registration requirement to get a grandfather clause document.
After I get my MA requirements all settled, it'll get relocated with the rest of my collection. At that point I'll have to keep in mind manufacturing and assembly standards for makers of uppers, but what about the parts I already have: ignoring the individual pieces on the quality spectrum for the rest of the parts (stock, recoil spring and buffer, trigger group, bolt release, and pins), how should I consider this Bushmaster receiver on the quality scale compared to other available stripped lowers?
And, within a given product class (cast, forged aluminum, forged steel), are there variances in quality that need to be considered or brands that are better than others when comparing apples to apples on manufacturing techniques?
