Cold Shot Scope Base Dial-Adjusts from Zero to +150 MOA

Cold Shot m.o.a.b. moab scope optics rail elevation 150 moa adjustment Angled RailAngled 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.

From Sweden — SPUHR Unimount Scope Mount System

When a scope mounting system costs as much as a factory hunting rifle, it better be something special. At $410.00, the Spuhr Unimount Scope Mounting System is one expensive piece of kit. But if you shoot .338 Lapua Magnums or 50 BMGs, this mount may be worth the money. Made in Sweden, the aluminum Spuhr Unimount integrates “rings” into a +20.6 MOA (6 MIL) base with built-in bubble level. The matte-black-anodized Spuhr Unimount has some interesting design features. The clasping bolts are set at a 45° angle. Ring internal surfaces are grooved for enhanced “grip” (these are not threads — the surface is precision ground and smoothed so there are no sharp edges). Available in 30mm and 34mm diameter (and various heights), the Spuhr Unimount even comes with a scope indexing tool to help you align your scope correctly with the mount. Along with the standard Unimount shown in the photo, a cantilever-sytle Unimount is offered for AR-platform rifles and other guns requiring forward scope placement.

  • Available as a standard mount or cantilever
  • Included scope indexing (alignment) tool
  • Built-in 20.6 MOA (6 MIL) Elevation

Magna-Tip Torx Driver Set from Brownells

Here’s a cool Torx driver from Brownells that belongs in every shooter’s tool box. The Magna-Tip Tactical/LE Field Torx Kit features a driver with five (5) Torx bits to fit popular scope rings and bases. A storage compartment in the handle holds the bits when not in use. A built-in magnetic socket in the handle holds each bit securely in the shank. We think this is a great new product. When Eyeballing a Torx screw, it’s hard to tell which size bit is required, and the short, L-shaped Torx wrenches that come with ring sets get lost all too easily. The $17.99 Torx Driver Kit, (Brownells Item 080-000-757), will help shooters keep all their often-used Torx bits safely in one place.
