A rear Picatinny plate is offered for the Auto-Ordnance 1927A1 pistol so a brace or stock can attach at the back of the firearm.

The part is meant to be printed with eleven walls at full infill in PA-CF6 or PLA-plus. Fasteners specified are two M4 machine screws 40 mm long with a 45 mm overall length plus two matching nuts.

Installation requires two holes through the bottom of the pistol lower, aligned to the adapter, drilled slowly from both sides so they stay straight.
