45 ACP caliber…best with Federal brand ammo!
Rock Island Armory OEM parts.
Built with hand selected RIA parts in our shop for the best starting point on your build. Each upper gets about a half hour of attention. Better than the builder kits where you may be rolling the dice on out of the box fitment. Fine tune fitting required. Full fitting and integration to your frame required. It’s the standard for 1911 builds.
Full size Gov 5 inch.
Tactical OEM “no logo” slide with wide rear serrations. RIA supplied these types of slides to STI and Citadel.
Great tactical feel to the serrations.
RIA Novak style sights.
Bushing barrel with bushing, link and pin installed.
Firing pin, stop, spring, and extractor.
Full length guide rod, 16lb recoil spring, and open plug.
The best affordable Upper – Top End on EBay or anywhere for that matter.
And a bit rare as I only get enough spare time to build one or two uppers a week, cherry picking my best finished parts to supply.
