Description
Proven Low-Profile Billet Performance
The MK Machining 30mm ULP Billet Scope Level is a compact, scope-mounted anti-cant level built for customers who want dependable vial visibility, durable aluminum construction, and a streamlined fit around the optic.
Machined from 6061 billet aluminum and finished with Type III hardcoat anodizing, the ULP provides lightweight strength in a proven low-profile design. Its hinged single-bolt mount installs directly around the 30mm scope tube for a secure, compact fit.
Compact Fit with Flexible Vial Placement
The level is designed so the housing does not extend beyond the optic’s windage and focus knobs, helping reduce unnecessary protrusion and snag risk. The vial can be positioned just beyond the turret profile for easy visibility or mounted on the underside of the scope tube when preferred.
The open housing captures available light for a clear reference from behind the optic, while the highly responsive vial remains quick to settle and easy to read—even in cold conditions.
Straightforward Installation
The hinged design installs around the scope tube and may not require optic removal when sufficient clearance is available. During setup, position the level where it is easiest to view, align the vial with the reticle, and securely tighten the mounting bolt.
The level can be installed on either side of the optic or beneath the scope tube depending on clearance, turret configuration, and user preference.
“Do I get a ULP or XLP Scope-mounted Level?”
The ULP is MKM’s proven legacy billet level design, offering straightforward functionality, durable machined-aluminum construction, and strong overall value. For customers seeking our slimmest billet profile and four-sided vial windowing, explore the newer XLP Level Series.
Why do I need a 30mm Ultra Low-Profile Billet Scope Level?
Just a few degrees of cant will cause considerable shot dispersion at longer ranges! If the scope is canted by only 2½ degrees, the bullet will impact .05 mils for every 100 meters in the direction of the cant. This means with only a 2½ degree cant and shot of of 1000 meters would be an impact of .5 mils. A small change can make a big difference and the MKM Ultra Low-Profile Billet Scope Level is the perfect solution.
But don’t just take our word for it. Here is a quote from Bryan Litz regarding Rifle Cant. Bryan Litz is the owner of Applied Ballistics and multiple time national and international competitive shooting champion.
As a general rule of thumb (for common cartridges) “a 1° Cant will produce five (5) inches of lateral displacement at 1000 yards. Thus, if you Cant your rifle just 8°, the POI would move 40″ from the center of the target, putting the shot off the edge of a 72″-wide target.” -Bryan Litz

Fit and finish on this piece is top quality and it is very discreet when mounted on the scope tube. Very easy to see when you are lined up behind the scope in the shooting position to confirm you are still at level.
I especially like how low profile the lower clamp section is, as my scope sits extremely close to the mounting rail.
I will continue to purchase these for all new setups.

You can tell immediately that this is a high quality piece of machining. Fits perfectly and easy to install. The stainless button is very clever and makes it easy to confirm level. Awesome product- thanks MKM!

I love the design and sleek fitment of this level, but the vial cracked and leaked out all the fluid in the level itself after only 20 shots…

Hi Chris,
Please get in touch. We had some thick anodization in vial slots leading to the pin pressing against the vial. We’ll get ya fixed up!

The quality of this scope level is even better in person. It works great with no issues and went on easy without taking my optic off my Savage 10.

I like this level. I liked the dark fluid which is easier to see as well as the steel bead in the center, makes centering super fast, easy, and intuitive. It’s pretty low profile and looks nice as well. I recommend spending the money to get this but the vortex low-pro might be pretty good too. No steel bead so I spent the extra few dollars for this one and I am not disappointed.

Solid, durable construction. High grade craftsmanship and the bubble is very easy to read. Installation was a breeze with the right tools. Doesn’t stand out in a bad way and the finish matched my Riton 5Conquer perfectly. Highly recommend

Very high-quality machining and design. Easy to install, perfect fit, and easy to see. Excellent addition to my hunting rifle.

Excellent quality and fits well on a sleek long range hunting rifle or a heavy match rifle. Will be buying more of these in the future.
