These magazine adapters for the SKS rifle will allow you to use any AR 7.62 x 39 magazine in your SKS, including 10 round XCR pistol mags! We have a run almost completed, 3 weeks away or so. Click the waitlist button HERE to be notifies as soon as they are done, or for our professional installation. These sell out fast, so don't wait too long. We also have the XCR pistol mags available for that, HERE.
