Frequently Asked Questions

Is this stock compatible with my AR-15 or AR carbine?

The CCSBLK is built to mil-spec dimensions and will fit any AR-platform rifle with a standard mil-spec receiver extension (buffer tube). If your rifle uses a commercial-spec tube, you'll need to verify compatibility or upgrade the receiver extension.

What's included with the stock?

We've provided the stock itself; verify with the product listing whether the buffer tube, spring, and buffer weight are included or sold separately.

How does polymer compare to aluminum for durability?

Mil-spec polymer is engineered to handle field use without cracking or warping. It's lighter than aluminum, won't dent or ding as easily, and requires no anodizing or finishing maintenance. For most shooters, the trade-off favors polymer unless you need maximum heat resistance or rigid mounting for night-vision or heavy accessories.
