The B5 Systems AR-15 Collapsible Precision Stock takes all the stability of a fixed stock and combines it with the versatility of an adjustable carbine stock. It features the same durable polymer build quality and fitment that B5 stocks are known for and wont rattle when attached to your carbine length mil-spec buffer tube due to the internal tensioners. The wide cheek rest provides a comfortable cheek weld and is elevation adjustable while the rubber button pad can be extended to ensure your head is positioned at the right height for your scope setup. Adding to the versatility of this AR-15 stock is the dual limited rotation QD sling slots, dual fixed sling loops, and bottom mounted M-LOK slots for attaching monopods or other accessories.Specifications and Features:Tube Included: No
