Remove optics or iron sights.
Remove the top rail (roll pin and Allen screw for Gen 1).

Remove fire control group screws and extract the assembly.
Remove trigger and disconnect.
Install the FRT and perform initial test fit.
Function check manually for any hangups.

Test Fire Procedure

Load 1 round — verify bolt locks back.
Load 2 rounds — test cycling.
Load 3 rounds — confirm reliability.
Full magazine — verify full performance.

If issues occur during testing, return to polishing, lubrication, and inspection steps.
