A few weeks ago I finally watched Garand Thumb's MK6 video and found it interesting to revisit the optic. For some time, my MK6 has been sitting in its mount on top of my safe looking for love. I was debating replacing the old ACOG NSN I have on my SR15, but that rifle is with my parents, so getting to it wasn't going to happen any time soon. After watching the video, I had a few reactions.

- It seems like, on some areas, he's shooting a different optic than I have
- Maybe I should give it another shot just as something different to do
- This would be interesting, since I put it back in a 1.5" mount instead of a 1.93" mount.

So, I decided to mount the whole setup back on my old N4 upper. I figured this was a good test-bed, and I've used it for other LPVOs. It's still very accurate (see below), fairly lightweight, and wasn't currently wearing anything other than a PRO RDS. So, after installation, it was time to rezero.

Warning: this isn't specific to the MK6, but it was interesting to see what I was able to achieve with "just" a 1-6 and a CL barrel. Mr. Noveske and company sure made some great barrels.

I decided to zero with CBC 77gr. I hadn't had the best luck with it previously, but not sure I tried it with this upper. The results were impressive, at least to me. I know there are many here that are better group shooters than me.



(ignore the upper left hole, that was from zeroing on another section of the target)

The big-ass dot in the middle of the reticle, coupled with the donut, don't make it easy to shoot a group, but I've covered that before. Not the point of the optic, so it is what it is.

Today I wanted to run some simple CQB distance, simple drills with transitions. I had two targets at different distances and at about a 60 degree angle from me. Due to some initial gassing issues with the first ammo (Silver Bear didn't have enough juice for the upper), I ran two different variations of strings on the two targets (plus a pistol transition to steel) for a total of 40 rounds. The MK6 is probably closer to the NF NXS 1-8 for comparison, so I'll mention it below, but for comparison, I'll mention the ATACR, as well.

Here are some takeaways:

- The lower head position was trainable. The bigger issue was eye box, but that was mostly okay. Out of the 10 dedicated strings I did, I only wandered out of the eye box twice, and not for all of the shots. Where the NX8 shines is when you wonder out of the eye box, you still see the dot. The ATACR, less so, but there's still a glow (and a MUCH larger eye box). The MK6...there is no dot.

- When the MK6 came out, other than the Razor HD, it was really the only other LPVO that had a daylight visible red dot in that price range (I'm not including the Elcan, which is also very bright). Today, at the highest setting on a post-rain, mostly cloudy day, it wasn't all that bright. I changed out the battery thinking that might be the issue, but no real change. It's still usable, but pales (see what I did there) to the NXS 1-8 and was still slightly dimmer than the ATACR, which isn't as bright as the NXS.

- Dot flicker...it still happens, but I went into this with an open mind and tried to not think about it. I think that helped. Yes, the dot would disappear at times, but using the "tunneling" of the reticle was still effective. Much like how many use the circle of the Eotech. I don't have comparative data at the moment to back this up, but it felt like I was slower with the MK6 while maintaining the same level of accuracy that I strive for. I'm not a fan of the 3-gun, "if it's on paper, it's a hit," type of scoring. That makes me slower than a lot of gamers (and that's okay). But I try to push myself for speed while maintaining A-zone hits. Compared to the ATACR or NX8, it feels like I could be fast with the MK6 with less accuracy, or slower with the same standard of accuracy. Obviously lots of variables there.

- Effectiveness...other than the .1-.2s slowdown (at times), it worked well. Coupled with a cheap, used T1 off-set, it seems like this optic could still be very useful. Eye box to eye box, I'd probably prefer the NX8, due to a brighter dot, but I may hang on to the MK6 a little longer and continue to play with it.

In the end, it's all fun and games anyway, but it was fun to play with the setup and I'll continue to do so. Pic of the current setup:



(Standard of accuracy for me is 25m and in, all shots must fall into the thick black circle. I make marks for those that fall out of the gray for trend analysis)
