MARBLE ARMS - TRITIUM SHOTGUN SIGHT

High visibility white outline with a tritium insert for day and night time use. The bead looks good and it's very durable. Great front bead for a simple home defense shotgun.

Perfect fit. Easy to install. I put it on my Mossberg 590 Shockwave. It gives you a good sense of where the gun is pointing in low light conditions.

Fits Armscor M5 shotgun and is visible over the heat shield . Love this bead and it is MUCH cheaper than other big dot sights that one must epoxy on the barrel. Just go slow when installing, I like to treat the threads on something like this as if it were a tap(half turn stop reverse repeat) mine was little too long, no worries just a little trim on a hone fixed it. Use high heat loctite.

As a replacement for the stock bead sight on a mossberg 590 with a breachers barrel (flash suppressor) it fit perfectly. In the light it's not noticeably different from the stock sight, and in the dark it's bright enough to see clearly - and not bright enough to attract the wrong attention. Installation was a snap. I matched it up with the removed stock sight - and they where the same exact dimensions. I had read that I should expect to file some - but after installation there was no need. Removal of the old was quick and easy, electrical tape over the jaws of a channel locks. I used red locktight on the new sight. Thanks Brownels for having it in stock and quick delivery.

Minor fitting required, took the threads down just a bit so it stayed clear of the barrel, but easy to do. It is a perfect replacement for the bead/fiber optic on my Winchester 1300 Defender. The original site is invisible in the dark, and this site is visible all the time. Exactly as I hoped it would be.
