Monstrum makes nice optics and this saddle, just another reason to keep shopping with these guys ### ⭐⭐⭐⭐⭐ Great fit *by R***. on March 31, 2026* As advertised, great fit, easy install.looks awesome ### ⭐⭐⭐⭐⭐ TOO TIGHT *by F***2 on March 17, 2024* 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. ## Frequently Bought Together - Monstrum Side Saddle Shotgun Shell Holder V2 | Compatible with Mossberg 590/Shockwave Series Shotguns - Miaozhun Tactical Shotgun Barrel Clamp Mount with Picatinny Rail, Shotgun Flashlight Accessories Mount for 12Ga Mossberg 500/590, Maverick 88, Remington 870, SXP Defender and More - CVLIFE Shotgun Sling with Shell Holder, Gun Sling Holds15 Shells for 12 Gauge, Adjustable Two Point Sling with Sling Swivels for Outdoors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/573637150-side-saddle-shotgun-shell-holder-v2-compatible-with-mossberg-590](https://www.desertcart.co.uk/products/573637150-side-saddle-shotgun-shell-holder-v2-compatible-with-mossberg-590) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
