STBA™ INSTALLATION KIT FOR STAINLESS TRIGGER & BUSHING ASSEMBLY for AR15/M16

Installation Kit includes one each of: Drill Bit, 1/4x40 Tap, Bushing Driver Tool

You will have to have available: Drill, Locktite, 1/8" Allen Wrench

This Installation kit DOES NOT include any bushings or receiver pins and only includes the installation tools which can be used many times to install receiver bushings on many receivers. The bushings and receiver pins that are installed in each receiver must be ordered separately online at STBA - AR15/M16 STAINLESS TRIGGER BUSHING & HEX HEAD PIN ASSEMBLY.

Although you could have a professional machinist or gunsmith do the installation, its generally not necessary.    Retrofit installation requires the hammer and trigger pin holes to be drilled and tapped to 1/4x40 to allow the bushings to be threaded into the receiver.  Obviously, once you install stainless steel bushings in your receiver you would not be able to later use standard hammer and trigger pins (and would have no reason to ever want to).  The installation is not technical and takes only about 5 to 10 minutes.
