ATI Advanced Technology Intl

Great product! Best bang for ur buck with the option of 9 slots and a rail! Easy install and worked perfectly with my mossberg 500! I would definitely recommend this to anyone looking for a side saddle and a top rail system.

Best price online and item arrived in time and perfectly packaged.

Perfect fit, easy instructions, holds 9 rounds which is great for having various ammo on hand as needed

You may have to grind a bit of plastic off the pump slide. Once the rail is attached the "stock" slide is prevented from going back as far as it needs to, this prevents shotgun from cycling a round into the chamber. If you have an aftermarket foreend slide you may not need to do this.The first picture shows how much needs to be removed as compared to the right other side.The second photo shows the slide back as far as it needs to be so that a shell can be released from the tube in preparation to be lifted up and pushed into the chamber.Aside from a bit of grinding with a Dremel I'm overall satisfied with this rig. It lets me keep the shotgun unloaded but with ammo only a second or two away.

Got this today and got it on my Mossberg 500 and the fit is nice and no wobble and it looks great, my only issue is the shell holders are a bit tight but im sure it will get loose after a while and if not I'll take a dremel to it.

First class product with perfect instructions and easy installation. I would recommend both the product and Amazon seller. To any owner of a Mossberg shotgun who is looking for a solution to the problem of how to carry extra shotgun rounds for fast access.

I use this on my Mossberg Maverick 88. I had to have a gunsmith drill and tap the top of my guns receiver then he attached this product. The rail does it's job and the side saddle for ammunition was initially real tight but with use has loosed enough to be practical for it's intended purpose.

Great option for more rounds on your shotgun….a bit heavy but great quality and construction. Well worth the money
