KRISS Vector MK1 Modular Rail

Are you tired of not having enough rail space on our KRISS Vector? Well, KRISS USA has come out with a modular handguard called the MK1 Rail. It slides over the lower recevier and bolts into the side where your side rails would normally be.

The KRISS Vector MK1 Modular Rail is designed as a bolt-on hand guard extension for your KRISS Vector CRB and is made from hard-anodized aluminum alloy.

The rail’s shape follows the form factor of the KRISS Vector’s body and is milled to reduce weight while still maintaining a rigid structure for support. The rail also has female threading along the three o’clock, six o’clock, and nine o’clock surfaces for the attachment of the included KRISS Vector Picatinny Side Rail Kit. It mounts directly to the body of your KRISS Vector Gen I and Gen II models.

I first saw the MK1 rail at the last NRA show back in April.

At first glance I thought they missed an opportunity to use MLOK rather than threaded holes and side rails. However that was due to my ignorance of the issues inherent in the design.

It’s all about the fit.

Looking at the Vector CRB, you can see how little space there is between the handguard and the barrel shroud. There is not enough room to use MLOK hardware as the locking nut and screw would interefere with the shroud. In order to accomodate MLOK or Keymod, the rail would have to be larger. Here it is a slim as it can be.

 

In the past there were limited options in extended handguards for the KRISS Vector.

The Diamondhead handguard extended the top rail for a better sight picture but offered little in terms of side rails.

And here is another option:

There are some airsoft quad rails that you could get like this one.

Or you had to modify a handguard like I did on my KRISS Vector carbine.

This was a Midwest Industries Gen 1 free float AR15 handguard. It was wide enough to fit around the barrel shroud and lower receiver.

According to KRISS USA the MK1 Rail has an internal diameter of 1.72″. This should be perfect for using a suppressor underneath the handguard. KRISS USA markets this handguard for the carbine Vector however you could use it on a Vector pistol or SBR. The only issue is if you dont use a suppressor then your hand is dangerously close to the front of the muzzle and exposed to the muzzle blast.
