B5 Systems has enhanced the Crane NSWC designed SOPMOD buttstock, incorporating features developed by military professionals and firearm enthusiasts. This ultra-rugged AR-15 stock was originally engineered to meet the demands of military special forces, built from mil-spec materials to exceed stringent durability requirements, and compatible with all mil-spec AR-15 receiver extensions.
The Enhanced SOPMOD is equipped with color matched steel hardware, one piece anti-rotation quick disconnect sling mounts, a non-slip cushioned buttpad, sure grip stock latch, and dual water resistant storage compartments. An ergonomic cheek weld supports consistent accuracy and recoil control, while the water-resistant storage design allows secure equipment storage. Each of the two water-resistant storage compartments will accommodate 3 CR123s or other similar-sized items.
The SOP-1123 weighs 12.2 oz and measures 7.43 in in length, 2.4 in in width, and 4.93 in in height, finished in wolf grey. Made in the United States, the B5 Systems SOPMOD represents a proven design trusted by operators and shooters who demand reliability and performance.
