STBA^Tm - STAINLESS TRIGGER & BUSHING ASSEMBLY for AR15/M16

Now you can have precision CNC machined Hex Head STAINLESS STEEL hammer and trigger pins on STAINLESS STEEL bushings in your new Tactical Innovations lower receiver or you can easily retrofit your existing receiver so you never have to worry about pin wear in  your AR15/M16.  Each precision machined pin is .154 diameter for a perfect no wiggle fit in the mating left and right side bushings.  We don't know how you could ever wear out a stainless steel bushing, but if necessary, the stainless bushings are threaded into the receiver and can easily be replaced.

AR15/M16 stainless steel fire control bushing assembly consists of (2) right side bushings, (2) left side bushings and 2 non-rotating .154 diameter hex pins.

Our stainless steel bushing set is available factory installed on both our T15 forged receiver as well as on our T15BDX Billet Deluxe receiver.   The bushing and pin set can also be purchased here as a retrofit that can easily be installed on existing receivers with the optional STBA INSTALLATION KIT.

Although you could have a professional machinist or gunsmith do the installation, its 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.
