Mossberg 500 shotgun saddle
Looks awesome on my Mossberg 500, easy to install, quality construction, the rail perfect fit for my red dot. Monstrum makes nice optics and this saddle, just another reason to keep shopping with these guys

TOO TIGHT
As others said you may have to open up unit so you WON'T mark up your guns finish. I used a 2x4 piece to hammer to spread out the tongues. I still marked up my mavericks finish. The screws provided to mount unit are soft and can strip heads. My holes did line up but the hole, that you install the screw through the open breach, on my gun was not threaded all the way through. Thus stripping the head of the provided screw. They did provide 2 screws, I wonder why? But only those two. THE SCREWS ARE AN ISSUE TO ME. THEY NEED TO PROVIDE MORE OR HARDER SCREWS. If you are going to clean your trigger, bolt, and other parts around them after every use, the soft screws are going to be an issue, in my opinion. The two screws in the pin holding in the trigger in place also holds the unit in place. If you did not spread the unit wide enough every time you have to pull the pin you will mark up your gun more to pull the pin. All of the issues I had and still see as issues I really like this unit. The rail is NOT a screw on rail. It is molded as part of the unit. The unit is stiff or firm NOT easy to bend. Thus why I had to take a 2x4 to try to spread to tongues. So I will say it is a solid unit. I like it !! I will update with any issues or likes.

Good product!
Bought this for a Maverick 88.Mainly for the ability to add an optic,but the shell holder was an additional plus.All 3 mounting holes lined up correctly,so installation was easy. I will say that the fit-up was tight(a great thing),but almost too tight.I put a piece of black electrical tape on each side before i slide it on,or it probably would've scratched the metal.Its made of quality materials.Shell holder holds the shells nice and tight. Would recommend to others!

Great no drill option
I got this as a gift for my Mossberg 500. Extremely easy no drill mounting. Very sturdy, no loosening with shooting slugs. Very happy to not have to drill and tap my receiver.

WHERE WAS QC!!??
So I bought a Monstrum first. Not only did it scratch my M 500 but the screws did not fit!? Same with the 590. The screw did not fit!? WOW!!! IT WAS SPECIFICALLY MADE FOR THE 500 AND 590... Mind-blowing. Nonetheless, I bought a Gotical the next day. Simple, no scratch, screws fit, install. And... you get a sight! Imagine that... Just the way it should be...

This side saddle is well-made and fits my 590 Shockwave shotgun perfectly. To install it, apply some gun oil to the bottom of the saddle to ensure it slides smoothly onto the shotgun. Using oil will prevent scratches. The main screw is a bit tight and requires being pushed from the inside out through the back of the shotgun to secure it, as the hole is not fully threaded for such a screw. Otherwise, there are no major installation issues. In terms of improvements, I would like the hardware to be flush, without a nut on the back to secure the screw.

I bought this for my Mossberg, it fit pretty good, I put a drop of oil on both sides of the receiver so it slid on pretty good without scratching the receiver. Added a little bit of weight. You can still use your front bead if you put an optic on which is a nice feature

Great quality product! Instructions are pretty bad but simple enough to figure out without them. Comes with additional hardware that’s not needed? As per other reviews a little bit of oil on the product and receiver will have it slide on with minimal scratching. Overall would definitely recommend, looks great and functional.

Well…. I had a decent review laid out for this shotgun mount, but I guess I’m not doing a review at all now because Amazon is ridiculously anti-gun and hypocritical, to no surprise. My original review was not approved, and I was told in the email, I had violated their terms because I showed a picture of my shotgun with the mount set up on it when I was reviewing the product I purchased, but yet they sell and allow firearms products and also show gun photos in product ads pictures. But I’m not allowed to post a picture of the product on my shotgun. Typical. Now after that little rant. Yes I definitely recommend this mount that’s all I’ll say as I can’t post any photos or videos just have to take my word. If you have a 590 and want to mount a red dot this is the way to go only issue the screws are cheap and can strip easily so be careful.
