CMMG Spring Action Carbine AR15

The CMMG Spring Action Carbine AR15 is a rimfire-caliber plinker and training platform designed for operators, LEOs, and enthusiasts seeking an affordable, low-recoil alternative to full-power centerfire AR configurations. This versatile firearm is ideal for training and recreational shooting, providing a reliable and enjoyable shooting experience.

Built on the proven direct-impingement principle, this carbine delivers reliable semi-automatic action with the cost efficiency and shooter-friendly handling that rimfire platforms are known for. The Spring Action designation reflects CMMG's engineering approach to reliable cycling across a broad range of ammunition without the complexity of adjustable gas systems. Its lightweight profile makes it suitable for extended range sessions where shooter fatigue from heavier centerfire rifles becomes a factor.

This platform serves patrol rifle training, civilian marksmanship development, and budget-conscious operators who require AR-15 ergonomics and controls without centerfire ammunition costs. LEOs and military personnel often use rimfire AR trainers for facility training, low-light work, and other tactical drills, allowing them to focus on fundamentals, sight picture, and trigger control without the punishment of centerfire recoil.
