## Description

Review: Slug shooters should take notice - I bought this to use on a Winchester Model 1300 Defender 12 gauge shotgun, that comes equipped with a small bead sight at the front. The installation of this Ultimate Arms sight was a good idea. The green sight collects a lot of light and the ease to align the barrel of the shotgun with the downrange target is greatly improved. I might add that I am using slugs through the Winchester, so target sighting is a bit more crucial than shooting shot loads. Installing this sight is just a little tricky in so far as the fit is quite tight, but it does go on with just a little patience and effort. It will fit. Once it is on, it is on for good. It does not move under slug recoil.. I was using the shotgun at 50 yards and easily getting 1" groups, centered.. The sight has a small notch in the front that captures the existing bead sight, so it self aligns. If you use a shotgun at a target range, this sight will add to your enjoyment. Recommended.
Review: Bright in sun - Snaps on to 12 ga with effort. Heating in boiling water seemed to help flexibility. Gathers light in sun for targeting. Will not help at night or low light conditions.

## Questions & Answers

**Q: Will this fit on a single shot 10 gauge?**
A: It's a tight fit on a 12 gauge. Assuming your 10 gauge is a larger outside diameter, if it fits, it will be very tight to get on. Hope this helps you.
