Tactical Quad Rail:
So far as we can tell, this is the first manufactured Mossberg 500/590/590A1/Maverick 88 quad rail produced [and what a great piece]! This Mossberg rail is the last word in quality accessorizing. Prepare to be blown away, because this is the real deal. This Mossberg 500/590/590A1/Maverick 88-compatible rail is beautiful and entirely functional. This work of art now allows any picatinny rail accessory, such as those on your rifle, to be mounted on the Mossberg 500/590 -even the 590A1 and Maverick 88. Take your shotgun to the next level! For more info see product listing.

Tactical Flip-Up Front Sight
A great addition to any tactical shotgun, this front sight features a quick-release mount for Picatinny/Weaver-style rail systems. The innovative flip-up feature allows quick access to traditional sighting when necessary while also being able to easily knock down when using an optic. This sight is elevation adjustable and constructed from aluminum. For more info see product listing.

Tactical Match-grade Detachable Rear Sight:
A great addition to any tactical shotgun or AR-15, this rear sight is compatible with Picatinny/Weaver-style rail systems. Features include a A2-style dual apertures with the larger Rapid Target Acquisition Aperture for CQB operations and the smaller Precision Aperture for high-accuracy aiming. This sight is both elevation and windage adjustable and is constructed from rugged steel and aluminum. For more info see product listing.

Tactical Billet Safety:
The location of the safety button on the 500 is ideal, but the design leaves a lot to be desired. Fixing the safety is probably the most common repair on the 500 series. For more info see product listing.

    The kit gave the shotgun new life! I purchased a used Mossberg 500 with 2 barrels, that had fallen out of the ugly tree and hit every branch on the way down, but hey couldnt pass it up for a $100. I replaced the stock and forend first, with an ATI Kit, since they were both cracked, followed it up with the combo kit from Vortex and all I can say is WOW!

    It is a pretty good product except for the pin that goes through the receiver. The bolts steered off and now i don’t know what to do. I dont think the small screws can handle the impact of the slugs being shot. I need a new reciever pin now. Can you send me one please

    I love this kit. The instructions were clear and it wasn’t a difficult job. Everything seems solid and well built. Best of All, It turned my Plain Jane Mossberg into one Bad-Ass looking weapon.

    All parts are of high quality with no visible defects. Installation instructions where present and concise. The Mossberg 590 was transformed to a completely different looking firearm while maintaining its functionality. I would recommend this kit to those who wish to update their defense shotgun from the standard OEM design. Only slight modifications are needed of bayonet lug which is required for proper fit and the removal of the rear sight. The only CON I can is you loose the ability to mount a bayonet and there are not any shotgun based combat sights available at this time. You will have to add a electric dot sight or modify an AR Type – or MIL-STD-1913 rail sight to create a larger peep hole. I would suggest modifying the over conversion to allow a bayonet.

    The kit was very easy to install and turned my 590a1 into a very bad ass weapon system …

    I am very happy with the combo kit it saved me money buying in bulk versus individualy. The only problem was some of the items were back ordered and the safety was shipped without the safety, just the hardware so it was sent later no charge.

    Awesome product. Would recommend to anyone.

    The Mossberg Combo Kit, UTG iron sight and safety replacement are all quality products in the their own right. The quad rail was very easy to install. My installation was on a Mossberg 590 Special Purpose which requires a slight trimming of the bayonet lug below the magazine tube. This was accurately described in the Vortex Defense youtube video. The addition of the rail noticeably reduced recoil.

    The nice thing about the front sight is that it is adjustable. The rear sight is also windage and left/right variant adjustable.

    I have not installed the safety switch replacement so I cannot review.

    I have to say that Vortex Defense have been very quick in order fulfillment and reasonable shipping charges. I did have a damage product return (not with this combo kit) but I wanted to say that their promptness in response to my email with RMA label and subsequent replacement of the item was fantastic. Vortex Defense has been a trusted customer service oriented organization.

    rail works well. goes on reasonably fast. the irons that came with it are not really made for shotguns. so there kinda useless. but its a good buy if you want to put accessories on a shotgun.

    I viewed the above product intially on a weblink. Once I saw the product, I reviewed it and went back again and again.
    I tried contacting various distributors with no response. I had a difficult problem. I live on the south east side of London in the United Kingdom. Vortex, not only replied to me, but were wiliing to work with me to find a solution. I am fortunate enough to co-own a company in the USA, so we discussed shipping the product to my USA office between the dates I would be visiting for our annual convention.
    I had question upon question, each was answered swiftly and effectively outlining what was best for me.
    I sincerely thank Eluid and the Vortex team for providing me with great customer service and advice I needed at the time I was researching. I can highly recommend the Vortex defense team. Thank you again, my Mossberg 590 A now looks great. Even my sons now think Dad is cool again !! Thanks guys – a job well done.

    The kit looks nice. However I’ve had to install 2 spare rails in the trigger housing after shooting less than 30 slugs. Until Black Aces Tactical can produce better screws for that pin slot, be prepared to buy a bunch of Spare Rail Hardware.That’s why it’s up there for sale. If they made better pin screws for it, this product would be top notch. It’s like the screws are made out of lead.
    Just did a stress test on those screws. It took about 100lbs to snap them. Maybe its a 590 problem. Friend of mine, arms specialist, replaced my 2nd Spare Rail Hardware, still same result. One screw failed after 16 slugs. It failed within the tube that the screw ‘screws’ into.

    Though I wish Vortex would go into the field and test the products they’re selling. The Reason I give 5 stars is because how they handle their business. Great Company, fast shipping, and good customer support.

    I had some technical difficult with the instal because my moss 500 didnt have the extended mag tube on it. Vortex Defense sent an extra part for the situation and unfortunately was unable to figure it out on my own. I emailed customer service and had a quick response with detailed instructions on how to install it properly. Its now on and works great. Thanks

    Fast shipping and easy to install. Looks great and adds plenty of mounting options. My kit was missing the spacers for the mount to the receiver and Vortex sent me them right away.

    Kit looked super awesome but first nine rounds I put through it one of the screws that attaches the rail to the rear of the gun snapped in half leaving the rail wobbely and unuseable will need a new pin and screw to fix.
