Adaptive Tactical Tac-Hammer RM4 Stock for Ruger 10/22 Takedown - Durable Black Polymer$110.66
Availability: In Stock
The Adaptive Tactical Tac-Hammer RM4 adjustable stock transforms your Ruger 10/22 into a modular, purpose-built rifle that adapts to how you actually shoot. Whether you're running suppressed plinking sessions, working precision groups at the range, or teaching a new shooter, this stock delivers adjustability and storage that typical 10/22 furniture simply doesn't offer. Built from reinforced polymer and made in the USA, the RM4 combines M4-style ergonomics with 10/22-specific engineering.
The real versatility lies in the removable barrel insert system—it accommodates both standard tapered barrels and .920" bull barrels, so upgrades and swaps don't force you to buy a new stock. The adjustable length of pull runs from 10.25" to 14.75", letting you dial in a proper cheek weld and trigger reach whether you're shooting prone, bench, or standing. Ambidextrous magazine compartments in the adjustable rear section keep two spare Ruger rotary magazines right at hand, so you're not fumbling for reloads or leaving gear scattered on the bench.
The patented Stowaway accessory rail deserves its own mention—it's hidden in the forend until you flip it out, giving you mounting real estate for a bipod or other rail-mounted kit without adding permanent bulk. The grip is spring-loaded for Tac-Hammer Monopod compatibility (sold separately), providing a single-point rest that pairs well with a front bipod for tripod-like stability. This is a stock built for shooters who want options, not a one-trick pony.
