The Black Collar Arms Stock Option delivers precision rifle features in an insanely lightweight, folding or fixed package. Bolts to any M1913 Picatinny rail.


Available on backorder. Please read and accept Lead Time Acknowledgment in configurator before ordering.

Specs and Notes:

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

• length of pull is adjustable. One 0.5″ and one 1.0″ spacer and all necessary bolts are included to provide four LoP adjustments (+0.0″, +0.5″, +1.0″, +1.5″). Length of pull may vary depending on firearm model on which Stock Option is mounted. Typically adjustable from approximately 12″ to 14.5″ on most firearm models. On our Pork Sword Chassis, LoP is approximately 12.25″ to 14.75″. The Stock Option itself will add, depending on the spacers you use, from 8.625″ to 10.125″ of length beyond the rear face of your firearm’s Picatinny rail.
• machined from billet aircraft aluminum.
• Mil-Spec Type III Hardcoat anodized black (Cerakote is applied on top of anodizing — we don’t skimp on that surface hardness!)
• only 10 ounces fully assembled with cheek riser, recoil pad, fixed mount, and all associated hardware. Stock Option with folding mount weighs just 12 ounces.
• Folding hinge mount can be flipped to fold stock to left or right side. Locks rock solid when deployed — ZERO wiggle. Simply pull rearward to open; hinge locks automatically in extended position.
• Ambidextrous QD sling sockets
