TriStar Arms Viper G2 Cmp 20 Gauge 24" 5-Round Shotgun

The TriStar Arms Viper G2 Cmp 20 Gauge 24" 5-Round Shotgun is a semi-automatic platform purpose-built for sport shooting, home defense, and tactical training applications where reduced recoil and faster target reacquisition are operational priorities. Designed around the 20-gauge cartridge, this shotgun delivers lower felt recoil than 12-gauge equivalents while maintaining effective pattern density at typical engagement distances. The 5-round magazine capacity and 24-inch barrel strike a balance between maneuverability in confined spaces and practical point-of-aim consistency—making it an accessible option for shooters seeking a modern, gas-operated semi-automatic without the penalty of full magnum recoil.

The compensator design (denoted "Cmp" in the model designation) incorporates ported venting to redirect muzzle gases upward and rearward, reducing muzzle rise and side-to-side movement during rapid fire sequences. This mechanical advantage allows for tighter shot groupings and faster follow-up rounds without requiring operator input correction. The gas-operated action cycles reliably across standard and light-target 20-gauge loads, a critical feature for shooters who reload or use a variety of ammunition types. At 7.56 lbs and 37.6 inches in overall length, the platform remains balanced and pointable while the 24-inch barrel maintains velocity retention for shot patterns that hold together to effective ranges.

Law enforcement trainers and civilian defensive shooters benefit from the TriStar Viper G2's softer recoil impulse, which accelerates skill progression and reduces shooter fatigue during high-round-count training evolutions. The 20-gauge platform is particularly advantageous for female operators, youth shooters, and those managing shoulder injuries or mobility limitations—all without sacrificing terminal performance. The 5-round capacity and semi-automatic cycling provide sufficient ammunition reserve and fire control for both tactical scenarios and competitive clay applications. Installation and maintenance follow standard shotgun procedures; no special tools or gunsmithing are required for field stripping or component replacement.
