B5 SOPMOD stock is the same general profile as the issued LMT SOPMOD. Cheek weld is comfortable. Lock lever was stiff for the first week of adjustments before easing up. Now slides cleanly to each position.
B5 Systems Government Issue SOPMOD stock in black has the QD socket that holds a sling tight under load. Stock locks at each position positively on a milspec tube. Polymer is dense and durable - holds up to abuse. Authentic SOPMOD geometry.
