Designed for speed, precision, and clarity of sight picture, our ATS COSUB sight is appropriate for most AR’s, AK’s, Submachine Guns, and Carbines. The ATS COSUB is appropriate as a primary sight, as well as co-witness and back-up sight.
Each sight kit includes:
- COSUB mount, clamps, and rear sight
- 5 differently colored front sights
- 5 differently colored rear sight inserts
- .044″ of elevation shim
- (pink = .015″, clear = .008″, tan = .004″, red = .002″)
- Front and rear sight set screw hex keys
**Firefly upgrade optional**
Amount of needed shim will vary, depending on firearm, caliber, load, and particular barrel and/or rail. Approximately, each increment of .002″ to .0025” of elevation shim will affect bullet impact by 1″ at 25 yards. The ATS COSUB does not need professional installation.
*NOTE: RED AND YELLOW FRONT SIGHT INSERTS HAVE BEEN REPLACED BY CORAL RED AND YELLOW FIREFLY FRONT SIGHT GLOW INSERTS.*
