The ADX Barreled Action is the best place to start if you are looking to build a custom rimfire rifle, pistol, or SBR. With top-of-the-line features and a preinstalled barrel, you are given the perfect foundation to create your ideal setup. 

This barreled action combines the TANDEMKROSS ADX Receiver, either the Spitfire or Comet Lightweight barrels, and the necessary mounting hardware. The barreled action ships with the ADX’s proprietary left-hand charging handle assembly, allowing for easy manipulation of the bolt using the support hand, and locking the bolt open by retracting the charging handle and lifting it up into a locking catch in the charging handle slot. To drop the bolt from the locked position, simply slap it down, and you’re ready to go! The ADX receiver is additionally compatible with standard charging handles, so if you prefer a conventional right-side charging experience, the receiver will accommodate your needs. 

Even cleaning and maintaining your ADX is easier than other rimfire rifles. Unlike its competitors, you can completely field strip the receiver of your ADX by simply removing just three pins. Successfully removing a bolt from a similar fully assembled rimfire rifle would usually take minutes and a combination of tools. This is now achievable with a single punch or other tool like a handy allen key or chamber flag. 

The receiver will ship with either the TANDEMKROSS’s industry-leading lightweight Spitfire barrel (16.5”), or Comet barrel (10.2”), which comes threaded ½”x28 for use with compensators, suppressors, and other muzzle devices. The tensioned barrel sleeve provides rigidity to maintain accuracy, but is cut for M-LOK® accessories, providing more space for lights, lasers, and more while also reducing weight and venting away heat. The sum of its parts allows for unparalleled accessorization on a barrel that punches well above its weight in terms of accuracy.

To finish out your build, you can use the TANDEMKROSS KrossFire Bolt for Ruger® 10/22® or your choice of bolt, your preferred trigger assembly like the Manticore or Manticore LITE, and the stock or chassis that suits your needs. 

Be sure to start your build off right with the ADX barreled action!
