KRISS Vector First Gen Stock Adapter

Regular price $39.99

SPARTAN MOUNTS ADAPTER KIT - Allows you to use your first generation KRISS Stock on your second generation Vector.  USA-made, 3D-printed for a precision fit, will not mark or scratch your gun. 

8/27/21 Update: This adapter has been redesigned from the ground up with tighter hinge tolerances, a more impact-resistant plastic, and the stock is now centered on the gun.  If you purchased one of the earlier generations and would like to upgrade, please email us with your past order number and we will give you a 30% discount on this new version.

UNIQUE, ATTRACTIVE DESIGN - PETG Plastic for superior strength and simple low-profile design. The Spartan Mounts adapter kit is the best way to adapt your stock for the second generation design.  Our adapter hinge attaches to the metal threads inside the gun, so that the larger plastic threads do not strip.

STRONG AND SAFE - PETG plastic is designed to be comparable to composite gun frames.

EASY TO INSTALL - Mounting to your gun takes only a few minutes.  Kit includes a hex wrench, machine screw, and o-ring.

EXCEPTIONAL CUSTOMER SERVICE -  Spartan Mounts receive consistently high ratings across all of our sales channels. We offer free returns if you have any issues or problems with the product. 

LIFETIME WARRANTY - If it breaks for any reason, we will replace it.

Well made

I have not installed it yet The thing that is concerning may be that installation is only effected by 2 set screws into plastic with plastic threads I don't know how sturdy it's going to be without some sort of locktight or epoxy
I will find out

Edit. I misinterpreted the installation I think it would be very solid

KRISS Vector First Gen Stock Adapter


Don't be fooled by the fact that it's 3D printed. This thing is as strong as it gets. Literally has zero flex and its really thick. High quality and STRONGGGG

Blake Powers

Works great, I am surprised Kriss don't make anything like this. It's the only way I could find to attached a hinged folding stock to the Vector I own

Gustavo lopez

I have a question dose this adapter allow the first gen stock to clamp to the side like the first gen?

Hey Gustavo,

Unfortunately it does not currently allow for the side latch. The first gen Vector's hinge was placed in an area that is not possible for me to re-create, so I was forced to make an offset which means the latches do not align.

Thanks for asking!

Was nice till it broke - UPDATE

I had previously said that it was nice until it broke which was true. But the customer support was outstanding, they contacted me and offered a full replacement free of charge, which was shipped quickly to my house. Greatly appreciate the effort put in by Spartan and wanted to make sure I updated my review.
