The BT28 AFAR Rail Kit will mount into accessory rails and provide a low profile 1913 Picitinny rail for attaching the Atlas Bipods or other accessories. This is a great option for shooters that have accessory rails and want to use their rail mounted Atlas on several rifles.


The uniquely designed rectangle nuts (BT28-N) fit both Freeland and Anschutz style rails by rotating them 90°.


Machined to Picatinny rail standards from 6061-T6 aluminum with Mil-Spec Type III Class 2 finish with 4041 Alloy Steel fasteners. Includes two rectangle nuts, two (2) 10-32 x 3/8″ flat head socket cap screws and two (2) 10-32 x 1/2″ flat head socket cap screws. Available in black only.


Length: 2.05″

Weight: 0.89 ounces



The BT28 AFAR Rail Kit is ready to install. The rectangle nuts will fit into some accessory rail slots in one direction or rotated 90 degrees to another dimension. We suggest using Loctite 243 when installing.

While we referenced what we believed to be bonafied “Anschutz” and “Freeland” rails, we have had some customers with “Anschutz” and “Freeland” accessory rails that the BT28-N AFAR Rail Nuts do not fit. We strongly recommend that you reference the dimensions in the third image above for the BT28-N AFAR Rail Nuts to ensure proper fit of these nuts in the slot of your accessory rail. These are steel and can be modified to fit most any slot, but the decision and liability in doing so will be yours.
