TANDEMKROSS ADX Pistol

The ADX Pistol is the pistol configuration of TANDEMKROSS's ADX line, an 18.5-inch rimfire pistol that takes Ruger 10/22 magazines and many 10/22 and 22 Charger components. The receiver moves the charging handle to the left side, where lifting it into a steel-reinforced notch locks the bolt open and a slap closes it, and a removable rear cap lets the bolt and charging handle slide out the back. Three pins field strip the receiver, and the integral extended Picatinny rail with its skeletonized channel carries the optic.

The 10.2-inch Comet barrel is a tensioned stainless barrel inside an M-LOK-cut aluminum sleeve, twisted 1:16 and threaded 1/2x28, so a rimfire suppressor threads straight on. The Manticore X Lower supplies the pull-weight-adjustable trigger, ambidextrous rotary safety, bi-directional magazine release, enlarged bolt lock, and reversible QD sling socket, and splits from the upper on two self-retaining pins. The M-LOK Forend for Manticore X, TANDEMKROSS V-block, KrossFire bolt, and Die Free Co Kung-Fu grip round out the build.

The pistol ships with a section of Picatinny on the rear of the lower for mounting a brace, set inline for tall optics and reconfigurable to a 12-degree drop for low sights, plus a buffer tube mount for telescoping braces. No brace or stock comes in the box. It weighs 41 oz unloaded and feeds from Ruger 10/22 magazines, with one DoubleKross magazine included. Adding a shoulder stock to the 10.2-inch barrel makes it a short-barreled rifle under federal law. TANDEMKROSS ships it to an FFL and not to California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Vermont, Washington, or Washington DC.
