The Atlas TRG Bracket (ATB) BT21 – Is designed for use with the Sako TRG line of rifles utilizing the TRG bipod attachment slot. The ATB provides a forward mounting position which is also closer to the bore-line. The ATB is designed for use with either the BT10 or BT10-LW17 Atlas Bipods which would mount directly to the Picatinny Rail portion of the ATB The AAIS is constructed from 6061T6 Aluminum with a type II hard coat anodize mated with an alloy steel Spigot that is finished with a Manganese Phosphate complete with fasteners

Please note: The Atlas BT10-NC can be mounted to the ATB, but this requires installation of the BT10-NC bipod during the installation of the ATB, prior to reassembly of the stock. This action will result in the semi-permanent dedication of that bipod to that particular rifle
