A few people have inquired about my Kriss Super-V SBR setup, so I thought I'd post a few additional details here along with some tips, tricks and what I did for my sling setup.

First, to recap the specifications: this is a stock Kriss SBR with Gear Sector hand stop, LaRue vertical grip, USP 16x1 LH 4-prong flash hider and a Surefire-Kriss E1B flashlight kit. I'm running an older EOTech 511 with the (new) standard BUIS - which are HK/M4 Kriss-marked Troys.

Out-of-the-box, the only sling mount that comes with the Kriss is on the folding stock - which is far from ideal. My initial attempt consisted of a Kriss push-pin/QD mount (which replaces one of the takedown pins) in a 1-point setup so I could run with either the stock open or folded, but this unfortunately placed the Kriss too low, too far away and at an odd angle. I tried 2 different locations - but to no avail. Scratch that.

The completed beasty. Tip: If you decide to go with the Surefire kit, you'll want to run something protective on the
underside of the light to avoid scorching the finish off. I just used some grip tape.


The second (successful) attempt came courtesy of some new gear: an Urban-ERT 2-point sling and two Gear Sector sling mounts - QD and 1" fixed loop.

Now the first question you might be asking is "Why the heck did he mount everything on the top?" And the answer is that there is only just barely enough room to mount a LH side rail, the close proximity of the charging handle precludes the possibly to install anything (there is zero room) and the Kriss rails are bloody sharp. I can't emphasize that enough...

Close-up detail of the forward sling point installation. I used a quick-release clip with the front point.

With a small/low-profile QD pin, I mounted the first Gear Sector attachment point just behind the front folding sight. I also left enough space such that it could pivot and rotate without hitting either the front BUIS (folded and open) or EOTech. I found that in practice, the sling didn't conflict and fell out of the way of the charging handle and didn't obstruct my line-of-sight.

Close-up detail of the rear sling point installation. I'm probably going to add a quick-release for the rear point as well.
Tip: There's about 1/8" of play in the push-pin for the Kriss stock, so I stuck a rubber grommet on the top to eliminate
this and create a bit more friction when folding or opening the stock.


For the second/rear Gear Sector attachment point, I had to move the rear sight forward about 1.25" and opted to install the sling loop as far back as I could. Again, I left enough room for the folding rear BUIS. As with the front point, the rear attachment also fell clear of the line-of-sight. I didn't add a quick-release to the rear of the sling, but this is something I may do at a later date.

The completed 2-point sling setup. Sweet! This shows the side rail that I've mounted in
order to clip the wires for the Surefire sensor pad which is adhered to the recess in the
stock that it's designed for.


The Urban-ERT slings are really awesome. In addition to being well-designed and durable, you can quickly reconfigure them from a 1-point to 3-point setup. All the buckles and adapters are a rugged polymer, so along with being lightweight and water resistant - they won't scratch the sh*t out of your Kriss. A quick-release is standard. The best part of the ERT system is that you can run the same sling on all your firearms and just change-out the adapters as needed.

Ultimately this setup works really great for me. I can snug the Kriss in really close and quickly lengthen it with a short tug when going to shoot. I can also run it with the stock open or folded for a more compact profile. I've got two quick-release points and may add a third down the road, and most importantly: it doesn't conflict with operating the Kriss.

Urban ERT was the best thing I brought back from shot-show. Makes my Tavor very happy having that on there.

Definitely like the setup you've got. Although I have to question the tape-switch and vert-grip plus handstop you've got running in the second picture.
 
RE the vertical grip:

How can you hit your tape switch with your hand folded between the stop and the broom-handle? Tell me you're not reaching out and around to tap that? Or some crazy left handed where you use your wrist to hit the light?

With a setup like that, I'd say it's worth jumping up to use surefires tape with a constant on
. . . I'm sure I could find the model number if I was bothered to grab the catalog off the coffee table.

Just seems like an odd grip+light interaction there!
 
Very nice blaxsun- I just read it. Any experience with the NR version- Better? Worse?

My analysis thus far....

The NR version is much longer than the R version.

The R version is much shorter than the NR version.


:D

Stay tuned for an upcoming range report....

Oh, that... It's rather simple, actually: I just drop my left hand back to the main chassis and grip there if I need to use the light (then it's easily accessible using my index finger). The Kriss is actually designed to be held that way when you don't have a vertical grip, as the front has a textured surface. In addition, the magazine ejection switch is too far back to reach when using the vertical grip anyway. Another option is to remove the vertical grip and mount the sensor on the right-hand side rail, but I prefer the current setup.

I haven't decided if I like the magazine release on the left side or if it's even possible to switch over to the right side. More range time is definitely required!
 
I would also like to add my observations:
The NR version is heavier than the R version.
The R version is much lighter than the NR version.
:D

One more thing I just noticed.....

They are both equally as hideous to the eyes, yet they are still perceived as awesome....they're the Justin Bieber of firearms.
