Layerform Precision sells a 3D-printed LP Target Rifle Chassis for Keystone Sporting Arms Crickett youth rifles. The stock adjusts length of pull, butt angle, height, and cheekpiece so a growing child can obtain a proper fit behind a scope. Removing the buttstock converts the rifle into a bolt-action pistol, while the forend accepts a Picatinny rail or a longer Picatinny-ARCA rail. A single factory action screw secures the action. The chassis costs 59.99 dollars and similar models exist for Savage Rascal and Winchester Xpert rifles, all sold by Layerform Precision.
