The laser is well packaged and easy to install. The supplied mounting screws fit my Mossberg 590 perfectly and the green laser is bright, especially inside or in dim light. I will be using my 590 for home protection so this fit my need perfectly. I also like the rail system and mounted a pistol light on it since I will be firing it from the hip and not looking down the barrel to aim. The combination works fine and the light works great for inside of a home or around the yard. I highly recommend the Monstrum Laser Sight System...especially for a Mossberg 590 where it is intended to be fired from the hip. Review: Parasitic Battery Drain - Parasitic battery drain: I must be one of the unlucky ones. While I see several outstanding reviews, there area few 1 star reviews and I will be adding mine to that category. There is some type of occult parasitic battery drain that results in a dead battery when the gun is put in storage. Like others, the 1st time it happended, I thought it must be my fault? I must have left it on. So second time I was very careful to be certain it was off, after testing it, and yet it still drained in about 2-3 weeks. I then (yet again) put in new batteries, confirmed they worked, but then removed and reinstalled the batteries without testing them. They lasted for months and months and were working fine when I did actually need to take the weapon from the safe and use it. Once tested, however, they too failed (drained out) in 2-3 weeks. Seems the only soultion is to NOT test the batteries, or insert them - but that just means the weapon is NOT ready at a moments notice - which OBTW - is the reason one keeps a weapon. ## Features - Laser sighting system built specifically for the Mossberg 500/590/835/930/Shockwave Series Shotgun platforms - Designed for rapid target acquisition in close quarters environments, when speed and visibility counts - Available in red laser sight or green laser sight versions for usability in different environments - Comes with an integrated Picatinny mount that allows for the mounting of Picatinny standard scopes, red dots, and other optics - Installs directly into the Mossberg factory mounting holes on the top of the receiver and is ready to use in minutes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CMFZZJVY | | Best Sellers Rank | #347,482 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #898 in Gun Sights | | Brand Name | Monstrum | | Color | green | | Compatible Devices | Shotgun | | Customer Reviews | 3.7 3.7 out of 5 stars (106) | | Item Weight | 2.91 Ounces | | Manufacturer | Monstrum | | Material Type | Aluminum | | Mounting Type | Picatinny Mount | | Night vision | No | | Product Style | Green Laser | | Sport Type | Hunting, Target Shooting | | UPC | 810088814457 | ## Product Details - **Brand:** Monstrum - **Color:** green - **Compatible Devices:** Shotgun - **Item Weight:** 2.91 Ounces - **Manufacturer:** Monstrum - **Material:** Aluminum - **Mounting Type:** Picatinny Mount - **Night vision:** No - **Sport:** Hunting, Target Shooting - **Style:** Green Laser ## Images ![Laser Sight System with Picatinny Mount for Mossberg 500/590/835/930/Shockwave Series Shotguns | Green Laser Sight - Image 1](https://m.media-amazon.com/images/I/51FifTplN9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Just As Advertised...Impressive quality *by K***E on November 29, 2023* The Monstrum Laser Sight System is just as advertised and shown.

Don't forget the blue Loctite! Use the supplied large Allen wrench to open the compartment on the front of the rail. The instructions show to open where the power switch is. Use some common sense! It also couldn't hurt to have extra batteries in stock. It uses two 1/3N batteries. The green laser is super bright in day or night. Zeroing in was a breeze. Picatinny rail is nice quality and not cheap plastic. Looks great. Feels great. Now I know this Shockwave is going to be spot on every time! ## Frequently Bought Together - Monstrum Laser Sight System with Picatinny Mount for Mossberg 500/590/835/930/Shockwave Series Shotguns - Pachmayr 05103 Tactical Grip Glove for Moss Shockwave & Rem Tac 14, Black - Monstrum Side Saddle 12 Gauge Shotgun Shell Holder | Compatible with Maverick 88/Mossberg 500/590/Shockwave Series Shotguns --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/582063538-laser-sight-system-with-picatinny-mount-for-mossberg-500-590](https://www.desertcart.hr/products/582063538-laser-sight-system-with-picatinny-mount-for-mossberg-500-590) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-22*
