A few days ago I received a very polite e-mail asking for scope advice. If memory serves me right, the gentleman who sent me the e-mail, was debating whether to keep his Razor HD LH 1.5-8×32 that he got a screaming deal on or to pick up a similarly priced 1-6x scope of some sort. The platform is a lightweight AR-15 chambered for 6.5 Grendel. I think.
The catch is that I very briefly skimmed through the e-mail, but since I was about to get onto the plane I filed it off as “this deserves a detailed response, so I should do it when I have a few minutes”. Well, I finally got a few minutes and I can’t find that e-mail to read through it carefully and answer it appropriately. I must have accidentally deleted it.
To the gentleman who contacted me: I will answer based on my rather vague recollection. If that does not cover it, please send me a note with more details.
For a hunting AR, I can think of few scopes better than the Razor HD LH 1.5-8×32.
In the grand scheme of things, for a civilian there are three reasons to have a 1-6x scope on a rifle:
- You want to use the rifle for self-defense/tactical classes where there is a need to use it like you would use a red dot sight.
- You are going to take the rifle hunting where you are shooting driven game or it is a big caliber boomer you use on DGR.
- You want your setup to look cool.
Outside of these three, it is often difficult for me to justify the compromises involved in having true 1x on the low end of the magnification range.
Now, for a rifle used as a plinker, the compromises are comparatively minor, since you will do most of your shooting during the day and you are mostly just having fun. However, for a hunting rifle, you want to think carefully before you put a 1-6×24 scope on there. Now, in the interest of full disclosure, please keep in mind that I happen to have Razor HD LH 1.5-8×32 as sort of a permanent scope on my hunting AR chambered for 458 SOCOM. However, since I also use this rifle to test scopes, it has had a few 1-6x and 1-8x variables on it (I am on the last leg of testing HiLux CMR8 1-8×26 on it right now).
There are a few reasons why you should think carefully before you put a 1-6×24 or something similar on your hunting rifle. Unless you are planning to spend a fair amount of money, most of these scopes are not all that good in low light at 6x. That is partly because of the smallish 20-26 mm objective (and corresponding small exit pupil) and partly because most of these are really optimized for low magnification. Higher end models are, naturally, quite good at all magnifications, but they are pricy and exit pupil restrictions still hold. The amount of light that gets to your eye at high magnifications where eye pupil size is not the limiting factor is proportional to the diameter of the objective. At 6x in low light, a 32mm scope delivers ~78% more light than a 24mm one.
Another problem is with the reticles. Most low range variables scopes out there today are really not designed for hunting and the reticles reflect that. Razor HD LH, on the other hand, was designed for hunting and the G4-BDC reticle is configured with that application in mind.

Sorry, the comment form is closed at this time.
Very good advice. Light gathering ability is a major component to hunting. Wants, needs, $$$ lot of things to balance. The farther you go into evaluating your wants the more complicated it gets.
Sometimes doing nothing is the right thing to do. If your current optic servers you well. So be it.
Buy another rifle.
Buying another rifle is usually a good idea…
Just out of curiosity can you point me in the direction to an alternative of Snipers Hide? It has served me well over the past few years but I have reached a point where I feel I can up my game and side step the sheep mentality. Between the heavy vendor back slapping and the ass kissing crowd. Looking for another site that addresses the finer points of rifle optics, hunting and custom builds. Precision shooting past 500 m is my passion.
Thank you in advance.
The Hide is probably the most active of the forums dedicated to precision. I am active on the Hide and on OpticsTalk. I also stop by 24HCF (this is mostly a hunting forum) and CalGuns. I used to visit AR15.com a fair bit as well, but moderators there seem to have issues with me linking to different articles on my website, so I will probably stop visiting that one for the most part.
OpticsTalk is probably the most civilized of the bunch.
Thank you sir
