The SLx MD-21 is an advanced micro dot sight that incorporates the latest technologies and materials to deliver exceptional CQB performance. Weighing only 5 ounces, the SLx MD-21 is both lightweight and rugged, featuring upgraded mounting hardware for guaranteed rigidity and precision when you need it most. If you are looking for a taller mount, check out the SLx 2.26" Mount for use with night vision or if you prefer a more headsup shooting position. The upgraded LED emitter offers complete night vision compatibility as well as a true Red Dot Bright™ reticle with an ultra-long runtime for full operability in any environment.
