Loaded with features built for the field and the range, the Tac-Hammer RM4 Takedown Rifle Stock adds portability and serious utility to the factory Ruger 10/22 Takedown. This compact, lightweight stock is engineered specifically for the factory Ruger Takedown 10/22 with standard tapered barrels (for bull barrel compatibility, see the TK22 Takedown Stock). The Patented Stowaway accessory rail is concealed in the forend when not needed simply reverse it to deploy a mounting point for a flashlight, bipod, or other accessories. The adjustable buttstock delivers custom length-of-pull on demand and includes ambidextrous storage compartments that hold two spare Ruger rotary magazines (magazines not included), so you're never scrambling for a reload. The pistol grip is sized to accept the spring-loaded Tac-Hammer Monopod for added stability from virtually any surface (sold separately). Compact enough to fit inside Ruger's factory bag or Copper Basin's low-profile 10/22 Takedown Backpack. Black polymer construction throughout.
