AR-50A1

The lower portion off the stock is milled away to allow the Precision Rifle ABR to be installed with only adding the height of the rider. 3 Bolts hold all the parts.

The Rules for adding an ABR

  1. Do not raise the rear stock more than absolutely necessary

  2. Space behind the grip to the front of the ABR minimum is 2+” so the adjustment hand is not hit during recoil

  3. ABR parallel with the bore
