Review: Perfect upgrade for Home Defense Shotgun, Easy installation and Great Results - Mossberg 500 - I decided to do some upgrades to my trusty old Mossberg 500 and one thing that always has been a struggle was finding a solid sight system for it. First I had an ATI heat shield with integrated ghost ring sights but they were made from polymer and mounted too far forward, kind of cheesy honestly. Then I attempted to modify a set of Tru Glos to work on this shotgun but sighting was impossible. So, this time around I was strongly considering the XS sighting systems Ghost ring rail with banded front night sight, which I would have loved to have but the $150 price tag had me on the fence for a 20 year old shotgun. But then it dawned on me, what good is a ghost ring paired with a night sight ? In a dark environment where your night sight would be imperative the black steel ghost ring would not be visible and possibly obscure your view of the front sight. So my best option I this case seemed to be this product. The price is right, installation was pretty straight forward and only took about 20 minutes not counting epoxy dry time and the result is excellent. The white big dot surrounding the tritium vial is very bright and easy to pick up and even as far away as the end of the barrel is the night sight is clearly visible in a dark room. A word of advice when installing , dry fit the sight and tape off around the perimeter. Use that as a grid to abrade the barrel finish only in the area needed, wipe thoroughly with alcohol before applying the epoxy, and the tip from another reviewer of using a zip tie to secure overnight was perfect. You Will Need to Purchase Epoxy for Installation, I ordered JB Weld along with the sight for another $4, worked great. I cant say 100% because I have only just installed it but as it stands now the sight is a great buy.
Review: Great sight. Installation couldn't be easier. - While it is a little pricey, this sight works and looks great and is super easy to install. I mixed a little JB Weld, roughed up the original bead sight and stuck this one down. I used q tips to clean up the excess and that was it! The sight is much easier to pick up than the original bead and has the added benefit of the tritium for low light situations. Wish I would have purchased it sooner.
