Cold Shot Scope Base Dial-Adjusts from Zero to +150 MOA
Angled Weaver-style or Picatinny-style scope rails elevation “pre-load” are commonplace these days. But most angled scope rails are non-adjustable. Cold Shot LLC offers a more sophisticated solution — an adjustable scope base that allows the shooter to “dial in” up to +150 MOA of vertical. The M.O.A.B. system works via a horizontal rotary adjuster with 1/4-MOA clicks, positioned on the rear of the unit. The M.O.A.B. 150 can be mounted on any rifle fitted with a full-length Picatinny Rail, chambered for any cartridge from .22 LR all the way up to .50 BMG. The M.O.A.B. system works well on AR rifles — when installed on any flat-top AR, the M.O.A.B. eliminates the need for extra-high rings or riser blocks.
With the M.O.A.B. 150, a shooter has more than 150 minutes of angle (i.e. vertical adjustment) calibrated in 1/4-MOA clicks, with a handy zero-stop. This allows you to stay centered in the vertical elevation range of your scope. In addition, the amount of elevation travel is sufficient to adjust for drop at extreme long ranges — a mile or more.
Some users will employ the dial-in adjustment just to set an elevation pre-load for a shooting session (more preload for longer range). However, because the M.O.A.B. offers precise 1/4-MOA clicks, you can actually use the M.O.A.B.’s click-wheel to fine-tune elevation settings, just as you might use the elevation turret on your scope. This saves wear and tear on your scope’s internals.
The price for the M.O.A.B. 150 is $399.95. Note: a +300 MOA version is also available for the same price — but we don’t know why anyone would need that much elevation. Made in the USA, the M.O.A.B. 150 (and 300 MOA version) come with a lifetime warranty on materials and craftsmanship.
Editor’s Comment: We are intrigued by this system. We like the idea of external elevation adjustment with 1/4-MOA clicks. However, the precision of such a system is dependent on the fit of the front hinge cross-bolt and the tolerances of the rear rotary riser. With a design like this, if there is any “slop” in the system, you could see a POI change from shot-to-shot. We have NOT tested the M.O.A.B. 150 so we cannot evaluate if the tolerances are up to snuff — this is just something you should consider before shelling out your hard-earned cash.
Bolt-On Version for M1A and M14 Rifles
Cold Shot also offers an adjustable scope base for M1A and M14-platform rifles. This unit has front and rear attachment points for a “no-gunsmithing” installation. Like the standard M.0.A.B. 150 scope base, the M1A/M14 version offers up to +150 MOA elevation travel in 1/4-MOA clicks.

If you are interested in this product (I just ordered one), watch the two videos on their site. Well worth your time.
Reminds me of my old Buehler Micordial Base only taken up a couple notches for extreme long range and greater ring options. The dial adjustments look better too. The Editor’s comments are well taken.
Brilliant. Hope they sell a million of them. Damned fine Yankee ingenuity!
Hope it works,,, but sceptical.
AGN Jett:
What’s with the negative comment? IF you have some hands-on experience with this product, speak up.
I am keen to see if the F-T class guys start using this. I love the idea for hunting, makes going from 100m to 800m much quicker.
waste of money. tested a lot this base. not correct returning vertical adjustments. poor workmanship. design errors can not be corrected.
Editors Note: a +300 MOA version is also available for the same price — but we don’t know why anyone would need that much elevation.
HUH? Nice write up but the above comment has me thinking you missed the point of this product. How about extreme long range shooting. The 150 gets me to 2100. The 300 is perfect. Why do you think they make it?
How well does it hold up to powerful recoil? How well does it track?
Any shot that will use up 150 MOA will come from a high recoil rifle-
so if it holds up to recoil and tracks well, its perfect-
if it fails in any of these two respects, its total junk-
Please let me know your honest opinions on this product- I’m building something to shoot way way far and Im seriously considering this product
Thanks
Im doing a project on laser alignment and would like to use the Cold Shot scope base to mount the lasers on. I need to get acurate measuements on different distances. Is there a supplier in South Africa?
Hi Martin.
Kon jy ‘n verskaffer vir SA kry?
i was a long range shoot this weekend and a guy had one on his rifle, he made a 2 mile shot(not at this event out of state) bullet had to be over 1000 ft above target. i am new to this so excuse my ignorance. over hearing the story from him and others. anyway i do not remember seeing one on any others rifle, well i am off for more info
This was already incorporated in the NTW 20: A Multi-Caliber Anti-Materiel Rifle.
Designed by the CSIR – South Africa in 1990’s – not a US invention!
