Lancer Tactical's CA-418B optic is modeled after the T1 Operator Red Dot. Featuring dual red/green illumination with 5 different brightness levels, this optic is exceptionally nice for CQB airsoft where quick aiming and lightning fast reaction speed mean the differences between winning and losing. With a build-in 1" tall riser, this optic is ideal for use on rifles where masks or eye protection makes is hard to get low enough to see through the optic. A quick detach lever allows you to quickly switch between optics or remove it for safe storage. Powered by an included CR2032 battery, this optic has unlimited eye relief and is build from a durable metal for impact resistance.
