Monstrum Tactical Grimlock Mounts – GAT Daily (Guns Ammo Tactical)

As a giant shotgun nerd, it may possibly get irritating to mount optics to completely different weapons. With handguns and ARs, we now have a reasonably typical optics footprint. Handguns have a number of completely different direct-mount optics, and ARs all have a flattop higher today. Shotguns, alternatively, all use completely different mounting patterns that depart you looking for mounts and rails to suit. Monstrum Tactical has determined that’s not ok and launched a collection of Grimlock mounts.

Should you’ve ever used the brand new Vortex Viper shotgun dot, you might have a good suggestion of how these mounts work. They’ve three slots. One is a single screw gap that’s easy and acts as your base. You align this gap with the rearmost screw in your shotgun and fix it.

Simply ahead of the bottom gap is a brief slot that means that you can mount the second screw. This longer, elongated slot means that you can put the second screw wherever it must be. Ahead of that slot is one other, even longer, elongated slot. Right here you possibly can mount your third and even fourth screw to complete mounting the optic. It’s such a easy concept that I kick myself for not considering of it.

Configurations and Compatibility

The Grimlock is available in three common configurations. We’ve got two direct-footprint mounts to work with RMR and RMSc optics. The third is a plain Picatinny mount for mounting any optic. I bought each the Picatinny mount and the direct RMSc mount. There’s additionally a Grimlock mount made completely for the Mossberg collection of shotguns.

The Grimlock mounts include #8-40 and #6-48 gunsmithing screws and can match mainly all Mossbergs which can be optics-ready, optics-ready 870s, the Benelli M1, M2, M3, M4, and, in my testing, it really works with the Nova as nicely. It additionally suits the Winchester 1300 and the Stoeger M3000/M3500 collection.

Nonetheless, if you happen to solely have a look at shotguns, you lack creativity. I used to be capable of mount the Grimlock to the Henry Homesteader, which reveals it really works with Henry rail footprints. I additionally mounted the direct-mount RMSc choice to my Rossi Brawler in .300 Blackout and not using a downside.

Mounted Up with the Grimlock

I’m a shotgun man utilizing shotgun mounts on weapons that aren’t shotguns. It appears foolish, however I needed to check the flexibleness of the optics mounts, and I’m pleasantly stunned by their flexibility. Since they value proper round $20 every, I’ll most likely decide up extra and begin outfitting my optics-ready shotguns with optics.

Equipping the Homesteader requires you to make use of the suitable screws. The Grimlock collection comes with a lot, however my preliminary mounting put the screws too deep into the receiver and caught the bolt. I swapped them instantly and by no means tried to fireplace the gun with the bolt dragging in opposition to the screws.

Everytime you use these mounts, do a perform examine. If it doesn’t really feel clean, then it’s not good to go. Fortunately, that’s not a troublesome repair for the reason that Grimlock mounts include so many screws.

Vary Testing: 9mm and .300 Blackout

On the vary, I figured the 9mm Henry Homesteader wouldn’t be an excessive amount of for the mount to deal with. I did suppose the recoil of a rifle spherical by way of a brief pistol is likely to be a problem with the Brawler. With the mounts mounted, I hit the vary with a wholesome dose of 9mm and .300 Blackout and let it fly.

The mounts held regular, aided by a dab of Loctite to the attachment screws. I zeroed my outdated Bushnell TRS-25 and Swampfox Sentinel 2 and shot a wholesome quantity of 9mm and 80 .300 Blackout rounds. Eighty isn’t a ton, however a field of .300 Blackout prices greater than the optic mount.

The mounts held sturdy. On the finish of the session, they remained in place, locked down and unmoving. Not unhealthy for a $20 mount.
