VLTOR VIS-KM SLIMLINE Polylithic Upper Receiver Assembly w/ KeyMod

This SLIMLINE models are a slimmed-down version of our VIS-KM series. They have a reduced profile, and a flat bottom panel.

After much demand from our customers, the VIS-KM has been modified to include a more streamlined version of the lower handguard. This flat bottom lower handguard allows for an overall height reduction, slimmer profile, and a wider base. Based solely in the KeyMod mounting system, the user will be able to attach any KeyMod accessory to the five mounting surface panels positioned around the barrel. The user will find that the flat bottom profile has improved ergonomics when in operation. This SLIMLINE version is quite popular with our customers in the competitive shooting world.

The VIS (Versatile Interface Structure) is a “polylithic” upper receiver assembly, in which the upper receiver and handguard have been permanently fused into a single, aggregate part. This design provides greatly improved structural strength and repeatable accuracy. The handguard is unable to twist or flex in relation to the receiver, and there is no gap present between the components. The VIS affords the user the benefits of a free-floating barrel, and solid-railed forend.

This VIS upper accepts all standard AR15/M4 barrels. No proprietary barrel assemblies are required, as they are with many of the other one-piece/monolithic upper assemblies on the market.  The lower panel of the handguard features a very effective heat shield. The lower panel is completely removable by way of two cam latches. The panel comes off to give you access to the barrel and barrel nut for installation and maintenance purposes. The VIS can also be used with the lower panel removed to accommodate an underslung grenade launcher.

FAQs:

1. Will a standard barrel nut work?
No. You do have to use the provided barrel nut and “one-time use wrench”

2. Do you sell an armorers version of the VIS wrench?
We do not. Our VIS wrenches are meant for one barrel installation. You can purchase additional VIS nuts and wrenches separately.

3. What kind of mounting block should I use?
We recommend that you use the Geissele Reaction Rod for installation. Damage could occcur if you use clamp-style mounting blocks or blocks that do not support the upper internally. This could void your warranty.

4. How do you remove the forward assist to install a custom dust cover?
Due to our Lifetime Warranty, we advise that you not remove or attempt to remove your forward assist. Our Lifetime Warranty covers all of our products as long as they are not modified in any way (i.e. disassembly, Cerakote, painted, Durakote, etc.). We do offer a service in house that will maintain your Lifetime Warranty. Please contact us to arrange this service.

 3. Will the Noveske KX3 fit underneath the handguard? Will a suppressor fit?

The Noveske KX3 or a suppressor will not fit underneath the VIS. The VIS only has a one inch diameter which doesn’t allow enough clearance.

4. What kind of mounting block should I use?

We recommend that you use the Geissele Reaction Rod for installation. Damage could incur if you use clamp style mounting blocks or blocks that do not support the upper internally. This could void your warranty.

 6. Do you make a VIS that is compatible with .308?

We do not current have a .308 compatible MUR available; however, our Research and Development team is exploring this area.

7. What is included with the VIS Upper Receiver?

Included with the VIS Upper receiver is the VIS Barrel nut, the VIS barrel wrench, and the M203 mounting bracket and screws.

8. I want to know how much barrel will be protruding from the handguard. How do I measure this?

If you visit the “specifications” tab it lists the handguard length. This measurement is taken from the barrel extension flange to the end of the handguard. You must first know the barrel length from the back of the barrel extension flange forward to determine the amount of handguard that will cover your barrel. *All measurements are nominal and subject to change*
