Brownells 75th Anniversary - A Shooting Heritage

America’s favorite rimfire rifle just got better! Introducing the CMC 10/22® Trigger.

The Ruger® 10/22® has long been America's favorite rimfire rifle.

The CMC 10/22® trigger is a drop in, self-contained trigger pack that is easy to install. Available in a Flat and Curved (CCT) bow design with a 3.5lb factory pre-set, non adjustable trigger pull weight. New textured bolt hold open button with auto drop function instead of the traditional lever commonly found Ruger® 10/22® rifles. It also features a fully ambidextrous textured magazine release paddle for quicker magazine changes.

The CMC 10/22® Trigger utilizes the most advanced manufacturing and quality control techniques. CNC-machined from a single piece of aluminum billet. The coating is rust-resistant and corrosion-proof. The use of aluminum and precision CNC machining allows for greater internal clearance. This clearance reduces drag and friction and provides a smoother felt pull. This trigger is extremely well made, much more durable than the standard stock Ruger® trigger and includes CMC’s Satisfaction Guarantee and Lifetime Warranty.
