Why the RAZOR - The Vortex RAZOR HD Gen 2 is the most unique high-end 35mm pecision rifle optic on the market today. It really differentiated itself among others for its scope finish, durability, performance and wider click adjustment range 125 MOA (36 MRAD) for long range shooting.

Any time when you see a 35mm tube size scope, you know it's definitely made for long range shooting.

This optic is quite popular in the long-range shooting communities as many people use it for hunting and competition.

EBR 7B reticle

EBR-2B Reticle - The scope features the open center aiming point EBR-2B reticle with holdover, windage and ranging capability. It's a reticle similar to the EBR-2C reticle as far as base functionality even though the 2C is a newer reticle with some slight changes in the subtension.

Superior Built Quality - What makes the RAZOR HD great on the Ruger is the unique color finish and sturdy turret design that will survive long term use for hunting and competition.

Mechanical RZR zero stop turret - Thanks to the integrated, mechanical RZR zero stop, you can dial all day knowing you’ll always have an accurate, repeatable and solid return to zero between stages or at the end of any range session.

Highly recommended this one if the Vortex PST 3-15X44 doesn't give you enough magnification.

Primary Arms PLx 6-30X56 FFP - Best For 6.5 Caliber

Why this scope - The Primary Arms Platinum 6-30X First Focal Plane 34mm scope is the best value for the money for the Ruger Precision Rifle, and it features the Athena BPR MIL reticle with holdover, windage and auto ranging features that long range shooters must have inside a scope.

Or pick the ACSS Apollo reticle designed for the 6.5 CM ballistic profile if you have the rifle chambered in 6.5

For the price of $1500, you are getting basically the same quality scope like the Vortex, but way more affordable.

Glass quality - Japanese made glass are the same quality as other NightForce and Vortex optics products. The only difference is that Primary Arms doesn't carry out extra rounds of in house quality control after it leaves the factory, which dramatically reduces the cost of their scopes.

The scope has tight tolerance to maintain accuracy. The zero-resettable elevation and windage turrets keeps the MOA / MRAD adjustment accurate for effective hits downrange.

6-30X is a perfect "all-in-one" package for anyone who wants to hit 600 yards and beyond. Not to mention the first focal plane gives you true reticle size at any magnification level, which is important for precision shooting.

Something like the Primary Arm PLx 6-30X FFP scope is hard to find in the world of precision rifle scopes. Get it at the best value price before they jack up the price as the company gets more reputable.

Common FAQ

MRAD (Mil) vs MOA

MRAD VS. MOA is a hot topic among precision shooters.

To simplify this... MRAD vs MOA is like comparing metric and imperial systems. Some people are comfortable with one, but can't wrap their head around the other.

So pick one that makes the most sense to you as the shooter where you can work through the math quickly in your head.

In fact, picking the right aiming reticle is the fundamental discussion here to truly understand what works for you. Ultimately it's the difference in units and what type of math you are most comfortable using in your head while out in the field shooting without getting confused.

Pick 1st Focal Plane Scopes

First focal plane scopes are highly recommended for long range precision shooting because the reticle is true at any magnification level.

Objective Lens - Size Doesn't Better

The bigger the lens diameter the better the light capturing ability. 32mm, 44mm or larger objective lens is considered large.

However, it's not always the case. Larger tube size provides more room for turret adjustment clicks.

Some entry-level scopes have large objective lens, but they don't guarantee the good light transmission or image brightness quality.

Adjustable Eyepiece

Almost every high-quality scope on the market comes with an adjustable eyepiece to ensure the reticle and the target remain clear and sharp for the shooter with different eyesights.

Parallax Adjustment

rifle scope parallax shift explained

Parallax is one of the most misunderstood concepts among shooters. Parallax occurs when the target and reticle are on different planes within the scope.

It is noticeable when the shooter moves his/her head or eye around the scope while the reticle appears to shift around the target at which you are aiming.

In the precision shooting game, the further the target is, the margin for parallax tightens, which means any slight offset can lead to a missed shot.


The mount height is a frequently asked question for Ruger Precision Rifle shooters. When picking a mount height you need to make sure it leaves enough scope clearance between the scope and the rail first.

Please use our scope height clearance calculator to determine mount height.

Everyone's cheek height is different so there is no perfect one size fits all.

Larger objective lens scope such as 50mm requires something like 1.6" or taller scope rings or mount.

The easiest way is to spot estimate the height between the scope and the rifle roughly, then go shop for the appropriate mount either at your local store or online.
