Overview
Built for shooters who want a collapsible stock with added utility, this model combines storage capacity with the familiar layout of the CTR platform. Its dual battery tubes hold CR123A or AA batteries and are accessed from the rear with hand-removable rubber plugs, making it a practical choice for keeping essentials close at hand. The reinforced polymer body, shielded operation lever, and supplemental friction lock are designed to help reduce wobble on the receiver extension, while the enhanced cheek weld and multiple sling attachment options support a more controlled setup. Buffer tube assembly is not included, so it suits users assembling or upgrading a compatible AR-15 or LR-308 platform with a Mil-Spec receiver extension.

Considerations & Trade-offs
- Storage tubes add bulk and complexity compared with a standard collapsible stock, so this model makes sense only if you want the extra onboard storage.
- The dual battery tubes are sized for CR123A or AA batteries, which is useful but limits what can be carried in the stock.
- Buffer tube assembly is not included, so this is not a complete stock setup by itself.
- The enhanced cheek weld and rubber butt pad are useful features, but the added structure may be more than some shooters want on a minimalist build.
