12 Gauge Shell Holder Side Mounted with Picatinny Rail Mount for Mossberg 500/590/Shockwave Series Shotguns

I put this on my Mossberg 590. Super easy install, holds the shells tight but not too tight, and it’s slim so it doesn’t get in the way of the slide like other side saddles. Great buy

I was going to rate 4 stars but am trying to be generous because the quality seems good especially since a comparable other brand was about $20 more of near identical dimensions. One or more other people in review commented that this shell holder covered part of the safety on the Mossberg 500. I found that to be the case. But using a hacksaw and grinder, I cut a notch out in a few minutes. Also, and this has nothing to do with quality, but I chose to countersink holes the shot shell holder so the tiny bolt heads would sit lower and allow better view to an optic sight I attached to the front. I just stored the rail. Anyhow, the bolt screws threaded in very nicely. The threads were excellent and the paint on everything was good. So if folks understand the small hurdles, this seems to be a good buy for the money. PS ... the shells hold firmly in place.

Easy to install and looks great.

Looks great, easy to install, amazing quality( wasn’t expecting that for $27) usually don’t write reviews, but this time I had to say how good that product is. Definitely buy again

It was exactly what I expected and it is well constructed and I am happy.

Fix was great and the installation was easy. Just be sure to put blue lock tight on the screws when installing.

Complete kit with longer high quality screws. Excellent construction and it fit perfectly. Shells slide in smooth and snug but not too snug, perfect retention. Thank you!

not worries on ammunition getting loose or falling… very solid… well design
