GRSC 1-10x Full Spectrum Optic Review

December 4, 2019

My background

With over a decade of law enforcement experience, both local and federal, I have utilized a wide verity of optics. Throughout the years I have had the privilege to attend a wide verity of shooting courses and trainings from local, to state, to DOD. I am also the lead firearms instructor and sniper on my team.  My primary experience with low magnification variable powered optics range from cheaper optics to primarily the Trijicon Accupoint 1.5-6 power, EO-Tech Vudu 1-6 power and the Vortex Razor Gen II 1-6 power. 

In last few years we have trained with some of the top tier operators and instructors in the United States. 

All that being said, the trend has been leading heavily towards short to medium range variable powered optics. 

First impressions 

Body and function

My out of the box initial impressions of the optic were that it seemed solid, a good finish. The number one thing that caught my eye and I really liked was the throw lever. Its size, shape, and texture made adjusting the magnification, very easy. It’s the most solid enhanced throw lever out of any of the low magnification variable powered optics that I have seen or handled. The turret caps spin off nicely revealing sturdy turrets that have nice solid click adjustments. The illumination knob is also well done with the off position in between each level of illumination. 


It comes with decent flip up scope caps which is nice. Also, the added bonus of the scope’s sun shroud and the anti-reflective lens cap is very nice.


The glass is clear and sharp, especially at distances compared to other scopes in the same price point. The 1.1 magnification was very slight but noticeable compared to a true 1 power. It is also misleading when on the scope it is labeled 1-10 power when it should be labeled 1.1-10 power. 



At one power I really liked the circle dot feel of the reticle much like the EO-Tech circle of death. I feel like it works well for CQC and close target work. However, the inverted horseshoe seemed just a little too thick. I like that it is there because it definitely catches the eye and directs you to the very center of the reticle. When aiming at something at 100 yards or so on one power, it was nice that I could still see the finest dot inside the horseshoe. It reminded me of turning on the illumination very low on a 1MOA dot of an EO-Tech for zeroing. I felt like I could really get a pinpoint shot, even more so than the fine crosshairs in Vortex Razor or the 2MOA dot in an Aimpoint. I also liked when the entire reticle e was illuminated. It almost seemed like a triangle sort of, like the triangle in an Accupoint or the chevron of an ACOG. What I did not like was how the horseshoe blocked a large amount around the target, making it difficult if there was a busy target down range, i.e. multiple people very close or in a hostage scenario or even just a paper target with multiple dots. I feel either more space around the center dot and the horseshoe or possibly a slightly thinner lined horseshoe may help with this.


First off, I have to say that it is awesome to see a 1-10 power optic, it is the first that I have seen and handled. Secondly, I love that it is a first focal plane scope. The way the reticle morphs from what seemed to be a circle-dot when not illuminated on one power to a Christmas tree-like reticle with elevation and windage holdover dots. This mimics my favorite long distance reticle, which is the Horus H59 in my long distance scopes. At ten power, the horseshoe is very thick and does obscure some of the down range sight picture. Also, unlike the H59 reticle, the GRSC FCO reticle is not based off of MRADS. The BDC reticle is designed to be used with the 556 round and is supposed to be user friendly with this round. It appears to be set up for a 50 yard zero adhering that the round strikes at the same place at 50 yards and 200 yard and slightly high at 100 yards due to the arc of the bullet. Then a circle-dot is the hold for 300 yards and the lines below for each additional 100 yards. I like that every other line is labeled with a number at the end of horizontal line for quick referencing. One of the issues with the BDC reticle vs MRADS or MOA is that if you are shooting at distance and you’re working off a spotter, he  could be giving you corrections if he is looking through a scope that does not have the same BDC in it. 

1000 Round Review  

The reticle is a little busy, but the BDC is super easy to use and almost fool proof after practicing with it. However, I was running into the issue past 300 yards where the lines did not correspond with my impacts. I was utilizing a 16” barrel and 62 grain Federal ammo. And I was hitting low past 300 yards which threw off the remaining BDC lines. 

I like the added ranging circles set at 10 inches for the range reference. Especially with the average human male’s head being roughly 10 inches from chin to top of the head. 

The thickness of the horseshoe cone is a little concerning to me as it can obscure objects surrounding the target down range that could be causal, such as in hostage or multiple target situation. Keeping the outer diameter of the cone/horseshoe and make it about half as thick, I think would help with it obstructing and it would still be thick enough to pick up quickly for this CQC snap shot situations.

I really like the size of the dots, as they allow for very precise shots with pinpoint accuracy. 

I like the numbering at the edges as a quick reference to keep you from getting “lost in the sauce” 

I’m confused by the thicker dots at 7, 8, and 9. I’d leave them the same size as the rest. 

The walking man and running man notches are a nice reference.

Learning the wind hold references (regarding the dashes or “clicks”, and the gaps or “half clicks” is a little difficult at first, as I am used to referencing MRADs in the .10 measurement. I’m sure after time and practice with a spotter, the lingo could be figured out, but I would rather see mil dots in the .25 or .5 range just to simplify the calls. Especially if my spotter is using a spotting scope with mill dots.

Final Conclusion 

I like the construction and glass. The throw lever, 1.1-10x magnification, first focal plane, sharpness of the reticle, and clarity of the glass were very nice. I would include an instruction manual how to use the BDC and possibly make some of the dots smaller and horseshoe thinner to make it a little less busy. Maybe even just illuminate the horseshoe and middle dot instead of the entire reticle to help with the busyness of the reticle, especially for CQC purposes. Just having basically a dot illuminated would help with speed of point shooting at CQC distances. Also, a true 1 power verses the 1.1 power is nice so you don’t get the distortion when doing CQC with both eyes open. Overall, I give the optic a B+.

GRSC 1-10x full Spectrum Optic Review

December 5,  2019


My background

I have been in federal law enforcement for sixteen years and have used a variety of optics. Throughout my career with special operations I have primarily used optics with no magnification because there was nothing on the market that could combine the EO-Tech like reticle with the ability to magnify without the use of an add on magnifier. In recent years we have seen a rise in these types of weapon optics and our team has specifically used Vortex Razors (1-6 power). 

First impressions 

Body and function

Gen 1 version:

Initial impressions of the optic was solid yet simple design. Nothing crazy fancy…sometimes companies just get too crazy with something and make it look flashy but it doesn’t really do anything. Not this. It is built very well. Turrets are easy to adjust but stay in place. The “throw” lever to adjust power is easy to use and doesn’t get in the way. 


Staying within the price point of this optic the glass is great. Very clear. There is some magnification at the “1” setting so I don’t believe the version I used is true 1 power. 


I am a small unit tactics instructor. I have always focused on close and mid-range optics. So I really like the circle with horse shoe and dot reticle. Training on close engagements from a CQC standpoint the optic is clear and easy to acquire. I will say that when illuminated (at one power) the horse shoe and dot all seemed to blend but was still accurate. With Mid-range is worked great. Again I like the design on the reticle and the use of it. There is a learning curve but that’s to be expected with any new reticle. I will say as you gain power the horse shoe does seem a little on the thick side. With that being said though that may just be something that training will overcome. 

Final Conclusion 

Overall I like this scope for the price range it sits. The 1-10 power is a huge selling point. From the “throw lever” to the reticle to the glass and the overall form factor everything is great. I would add some instructional manuals though. This will shorten the learning curve. The only downside for me personally was the 1 power magnification. That did distort vision a bit with both eyes opened in a CQC engagement.
