Warne Universal Receiver Red Dot Mount: Put a Red Dot Straight on Your Drilled-and-Tapped Shotgun

Channel fans and family, here’s one for everybody who has stared at a perfectly good pump shotgun and thought, “This thing needs a red dot, but I don’t want a giant rail sticking up off the receiver.” Warne, the Oregon scope mount company, just announced its Universal Receiver Red Dot Mount. It’s a small plate that bolts a reflex-style red dot right onto the existing holes of a drilled-and-tapped receiver, mainly shotguns.

It’s not flashy, but this is the kind of part I actually like. It does one job, keeps the dot low, and uses holes your gun most likely already has.

Quick note: this is a release announcement built from Warne’s press release and its own product page. We haven’t mounted one yet, so nothing below is a hands-on impression.

How it works

A lot of shotguns, especially pumps and older semi-autos, leave the factory with a couple of tapped holes on top of the receiver. Normally you’d put a Picatinny rail there and then stack a red dot mount on top of that. Warne skips the middle step. The red dot screws directly to the plate, and the plate screws directly to the receiver.

• Two-hole mounting. It uses two of the receiver’s existing holes. Warne suggests the two holes closest to the front (barrel end) of the receiver.
• Oblong hole for flexibility. One of the mounting holes is slotted, so the same plate can fit different hole spacings.
• Two screw sizes in the box. Warne includes both 6-48 and 8-40 screws, the two thread patterns you’ll most likely run into on receivers.
• Low and light. Keeping the optic close to the receiver gives you a more natural sight picture with a shotgun, where your cheek weld sits pretty low. The plate weighs 3 ounces.

Red dots Warne says it fits

Here’s the compatibility list from Warne’s product page:

• Burris FastFire 2 and 3 (uses the included hardware)
• C-MORE RTS and STS
• Docter
• EOTech MRDS
• Holosun 507C/407C, V1 and V2
• Insight MRDS
• Leupold DeltaPoint and DeltaPoint Pro
• Shield RMS
• Sig Romeo1 Pro, Romeo3, Romeo3 Max and Romeo3 XL
• Trijicon RMR
• TruGlo
• UTG Reflex Micro Dot
• Vortex Razor, Venom and Viper
• Others that share the same hole patterns

That covers most of the dots people actually own. If you’ve got an RMR, a Venom or a 507C sitting in a drawer, chances are it’ll bolt on.

Heads up: the press release and the product page don’t fully match

I checked the announcement against Warne’s own product page and a couple of things don’t line up, so read the fine print before you order:

• Hole spacing. The press release says the mount works with receiver hole spacings from .475″ to 1.61″. Warne’s product page for the 6113M says .500″ to 1.135″. That’s a big difference if your receiver holes are spread wide. Measure your gun and confirm with Warne before buying.
• Rifles. The release says that besides shotguns, the mount works on select rimfire rifles, including the Ruger 10/22, plus other compatible rifles. The product page only talks about shotgun receivers and doesn’t list the 10/22 or any rifle.
• Name. The release calls it the “Universal Receiver Red Dot Mount.” The product page calls it the “Red-dot Shotgun Receiver Mount.” Same part number, 6113M.

Who it’s for

• Turkey and deer slug hunters. A red dot on a turkey gun or slug gun is faster and easier on the eyes than beads or rifle sights, especially at dawn.
• Home defense shotgun owners who want a dot but don’t want to add a tall rail plus a mount.
• Clay and casual shotgunners curious about trying a dot without a big setup.
• 10/22 owners, if Warne confirms the rimfire fit from the release. It could be a clean, low way to run a mini red dot on a plinker.
• Anyone with a spare pistol dot. Most of the footprints listed are pistol-size optics, so this is a good use for one that’s sitting in a drawer.

Mounting tips

The usual rules apply. Degrease the screws, use a little thread locker, and don’t overtorque small screws going into a thin shotgun receiver. If you’ve never mounted a red dot before, we walked through a full install (screws, thread locker and torque) on the Ruger Max-9 in the video below. It’s a pistol slide, not a shotgun receiver, but the habits are the same.

Our take

I like this. Warne isn’t reinventing anything. It’s taking a step out of the stack, and on a shotgun that’s exactly what you want: the dot sits low, there’s less to come loose, and you use holes the factory already drilled. Using one plate for a dozen-plus optic footprints makes it easy too. The part I’d watch is that hole-spacing mismatch. Until Warne clears up whether it’s .500″–1.135″ or the wider .475″–1.61″ in the release, measure your receiver and ask before you buy. Same goes if you’re buying it for a 10/22. If it does fit your gun, it’s a simple, made-in-USA way to get a red dot on a shotgun without the tall rail.
