Very cool.
Whoa…when’s the middy and/or rifle length due out? Thanks. I have a Noveske 12.5" barrel w/OPS stuff…inbound…and that middy is calling me…
I don’t like promising any dates, but we are working on 300 mid-lengths as I write this post. I hope to start shipping in the weeks to come. Rifle-length will be available by the end of the year.

What about a super SPR 240" VIS for my AirSoft ?
All kidding aside, great stuff eric, I cant wait to get ahold of one to mount up !
Eric-
How are the markings on the upper done? I really like them a lot. Most pictures don’t show the detail of the markings. None of the pictures I have seen show the detail of the lettering with that deep black outline that makes it really sophisticated looking. Nothing at all like the LMT upper I had with a few thin lines etched in and then filled with a white substance.
Anyway, I wanted to compliment you on the appearance of the markings and ask how it is they are created to look that way?
Joe
Excellent. Thanks!
Joe-
There are many lasers, but without getting complex, the best way to describe it is there are Lasers that mark and lasers that mark and engrave. Per AFT rules, laser engraved serial numbers must penetrate more than .005 in depth into the parent material. So, when picking a marking and engraving laser, we went with the best. The Trumpf system gives us the best quality/detail (ideal for the UID marks) and has excellent penetration for serializing weapons receivers. Our current engraver cost 100k and new model (with larger work space to do T marks) will run 200k plus. I guess we need to sell a few more VISs and buttstocks to pay for that bad boy.

Eric-
I’m not sure you took my last post as a compliment and wanted to make sure you did. I really like the engravings and am not complaining about a lack of T-numbers.
I was curious about the neat black outline effect that the letters have at the moment…
I have no problem in taking a compliments. Thanks!
Personally, I’m not much of a fan of the T marks either. The T marks were a SOPMOD requirement and I highly doubt that the VIS will ever be a SOPMOD runner-up. In the long run, I may wait to see what the customers/end users want. Who know, the VIS may never see T marks.
Once again, thanks for the interest and compliment.
Eric
very informative post so I censored my supercilious comment
Eric,
Can you explain the process of removing/installing the barrel?
From the pictures that Grant posted it looks like all I really need
is a torque wrench used with the barrel wrench that you provide?
Thanks in advance.
You are correct. All is needed is a 1/2-inch drive torque wrench set at 50 foot pounds and grey never-seize compound (applied to the barrel nut thread).
Now for the legal shpeel: The barrel installation and removal should be preformed by a qualified gunsmith and/or armorer. The wrench that is equipped with each kit should only be used one time, then promptly disposed. In the near future, an armorer’s wrench will be available for continuous usage.
OK, back to the basics. After the VIS barrel nut is installed, onto the barrel assembly the barrel can be installed. The beauty of the VIS system is that the barrel can be installed with the gas tube installed. The barrel nut functions freely with the gas tube in place.
With the barrel installed, one just needs to tighten the barrel nut down by hand. When snug, use the barrel wrench to tighten the nut the rest of the way. The VIS has enough room to rotate the nut and wrench 1/4 turns at a time. With the nut torqued to the recommended 50 foot pounds, install the lower handguard and you are good to go.
In all, it’s a pretty simple system. Under normal circumstances, a barrel can be install and removed within 5 minutes. Legal shpeel again: Vltor does not recommend the VIS to be used as a quick change barrel system. The barrel should never be removed other then to repair/maintain or replace the existing barrel. When changing the barrel, we recommend the your qualified gunsmith/armorer to use the robust Vltor armorer’s wrench.
I hope I answered your question.
Eric
Thanks for answering my question.
Just curious as to why the wrench that is currently supplied with the kit can only be used once?
Can an “off the shelf” barrel wrench, say from Brownells, be used for the installation or does it specifically require the VLTOR wrench?
VLTOR will be providing hardened wrench in the future. You can most likely get a couple installs out of the wrench provided.
You cannot use any other wrench, but the VLTOR.

What is the width of the rail compared to say a DD of LaRue?
I’ll second that question, but I’m also wondering what the internal diameter of the rail is at the smallest point. For instance, would it be able to cover a KX3 flash hider?

With some quick checking, here are the widths I came up with:
VIS 2.260 inches
DD RAS 1.935 inches
LT RAS 2.0 inches
DD Lite Rail 2.050 inches
The reason the VIS is wider then a conventional RAS is because of the barrel nut, which needs to fit inside. Also, I wanted to make sure the Picatinny rail were true MilStd 1913.
The bore of the VIS is rather tight. The narrowest part is a little more then one-inch.
I hope I answered all questions.
Eric
Would love to have one with an 18’ Noveske 6.5 Grendel.:eek:
But how will we know what the top of our rifle is without them :eek:
