STBA^Tm 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. 

We will also retrofit install STBA bushings on our T15 and T15BDX receivers for customers that previously purchased one of our receivers and now would like to have their receiver include the STBA upgrade. Due to the considerable variation in other manufacturer's receivers, we do not retrofit receivers other than our own although many customers have successfully done so. The cost for the installation as well as the paperwork and handling associated with receiving and shipping your receiver is $25 plus $12 for return shipping in addition to the cost of the STBA parts as described herein, making the total cost of the retrofit with return shipping $62.00. Please email for shipping instructions prior to shipping your receiver.
