Stock Option


Temporarily on backorder status. We’re pausing Stock Option sales until our folding mount is ready.

Specs and Notes:

• direct fit to any M1913 Picatinny rail! Use on a Black Collar Arms chassis or on dozens of firearms such as SIG SAUERs, CZs, BRN-180, AKs, and many other rifles with a native rear Pic rail or an available Pic rail adapter.
• adjustable cheek rest (quickly and highly adjustable for height, five-position adjustable for front-rear location). Stock is also comfortable for use with cheek rest removed.

• comfortable and grippy rubber recoil pad
• 7075-T651 aluminum construction (fixed and folding mounts plus stock body)
• Mil-Spec Type III Hardcoat anodized black (custom coatings applied on top of anodizing — we don’t skimp on that surface hardness!)
• only 10.6 ounces fully assembled with cheek riser, recoil pad, fixed mount, and all associated hardware.
• Folding hinge mount can be flipped to fold stock to left or right side. Locks rock solid when open. Spring detent holds stock folded. Simply pull rearward to open; hinge locks automatically in extended position. Folding mounts are still in the works! Orders for a folding and fixed stock will ship now with the fixed mount and the folding mount will ship on its own when ready. ETA Q4 (entering full production right near Halloween).
• Dual, ambidextrous QD sling sockets at top and bottom rear

Please email our boy Jeeves at with any questions.
