20 Gauge Universal Split-Ring Shotgun ATS Sight:
There is no iron sight for shotguns that is faster than ours. Our 20 Gauge Universal Split-Ring Shotgun sight is designed to go behind factory front sights and over magazine/barrel clamps. Removal of factory sights and clamps are no longer necessary. Each sight kit includes:
- 5 differently colored front sights
- 5 differently colored rear sight inserts
- .044" of elevation shim
(pink = .015", clear = .008", tan = .004", red = .002")
- Front sight, rear sight, mount and clamp set screw hex keys
- Two sets of ring shims that go between the barrel and rings in the event of a smaller 20 gauge barrel diameter.
With our 20 gauge shotgun sight, start with 020" of shim for an approximate 25 yard zero with slugs. 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 shotgun sights without professional help.
