The Swampfox Optics SNL2120GMS Sentinel II Black 1x20mm 3 MOA Green Laser is a micro pistol red dot built around a generous 20mm window and a slim RMSc footprint. Its rugged aluminum housing, fully multi-coated lens, and patented removable rear sight guide work together to keep your sight picture clear while preserving a familiar alignment reference for pistols that lose their rear irons when mounting an optic.

This compact sight is ideal for concealed carry, home protection, and regular range practice where fast target acquisition and a crisp 3 MOA green dot are priorities. Unlimited eye relief, Shake N Wake auto on/off, and parallax-free performance beyond 33 yards make it easy to run on modern optics-ready slimline pistols. Sentinel II reflects Swampfox’s focus on practical innovation, thoughtful ergonomics, and dependable performance for everyday shooters.
