Daniel Defense Delta 5 Pro

Modify the ABR to mount to the existing slot (drill and tap holes in ABR). Mill holes in the rear stock to allow the longer dowels and stud to pass thru the lower section. Drawings to assist are available. Flat Mount ABR with short dowels are in pic.

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 2.25” so the adjustment hand is not hit during recoil

  3. ABR parallel with the bore
