The STR offers features similar to our CTR® stock and adds two water-resistant storage tubes along the cheek weld area. The tubes don’t protrude or obstruct the shooter, and they and hold up to two CR123A or AA batteries each. The STR maintains the CTR’s streamlined A-frame profile to avoid snagging, and the ambidextrous release latch and friction-lock system provide quick, dependable adjustments that lock down tight and keep the stock in place during hard use.

Made in the USA.
