Description
The ISSC MK22 *CA Approved* 22LR 16″ Barrel 10 Rd Mag, Fixed Stock, Black is a California-compliant rimfire rifle designed for high-volume, low-cost training and plinking.

Frequently Asked Questions
Q: Is this rifle compatible with standard AR-15 parts?
A: While it shares the ergonomics and manual of arms, the ISSC MK22 is built on a dedicated .22 LR platform. The upper and lower receivers are specific to this system. However, many external accessories like handguards, pistol grips, and optics that fit mil-spec dimensions will work. Always verify compatibility before purchasing parts.
Q: Can the fixed stock be replaced with a collapsible one?
A: To maintain its compliant status in regulated jurisdictions like California, the fixed stock must remain installed. Modifying the rifle to accept a collapsible or folding stock would alter its legal classification. For unrestricted states, check local laws and consult a qualified gunsmith, as the receiver extension may be proprietary.
Q: What kind of accuracy can I expect?
A: With its 16-inch barrel and typical .22 LR ammunition, the ISSC MK22 is capable of minute-of-squirrel accuracy at reasonable distances—think 50 to 75 yards. For best results, use quality, high-velocity ammunition and consider adding an optic. It’s a plinking and training rifle first, but it’s more than capable for casual target shooting and small game.
