    Quality

    30 years as an Army armorer and I've handled more Ma Deuces than I can count. This barrel support is legit mil-spec, miked it out when it arrived and everything checks to print. Dropped right into my semi build with zero fitting required which is exactly what you want with these parts the M2 platform doesn't tolerate sloppy tolerances. Parkerizing looks correct and consistent, no tool marks or burs anywhere. If you're building or replacing parts on a deuce, don't cheap out on critical components like this. This one is good to go.

    Dead on mil-spec dimensions, verified with calipers and it's spot on

    Price is steep but that's the reality of M2 parts in general, not specific to this seller

    Great part. Well built. No complaints.

    Brand new

    No military part or casting numbers. No big deal for me.
