Universal Bull-Barrel ATS Sight:
This sight was built for speed. Our Universal Bull-Barrel sight is designed for bull-barrel .22's and military spec. shotgun barrels. These are not split-ring sights and must slide over the barrel from the front of the muzzle. This may necessitate the removal of factory front sights. Each sight kit includes:
- 5 differently colored front sights
- 5 differently colored rear sight inserts
- .063" of elevation shim
(metal laminated shim = .034", pink = .015",
clear = .008", tan = .004", red = .002")
- Front sight, rear sight, mount and clamp set screw hex keys.
Our universal bull-barrel sight comes pre-installed with .034" of laminated shim, for an approximate 25 yard zero with .22 long rifle ammunition. Approximately, each increment of .002" to .0025" of elevation shim will affect bullet impact by 1" at 25 yards. With the tools provided with each sight kit, most will be able to install our universal bull-barrel sights without professional help.
