KRISS Vector First Gen Stock Adapter Hinge

KRISS Vector First Gen Stock Adapter Hinge Features

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 only takes 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.

Perfect adapter

If you have a gen 2 vector and you want to run the gen 1 vector swing stock, look no further than the spartan mounts adapter. It looks great and functions even better. Fantastic product, thank you spartan mounts!

It looks Great, I really love how lightweight it is, but definitely feels real sturdy.
I haven’t been able to install the complete Set-up —> “Stock/Brace with the Adapter & TailHook Mod1c” from Gear Works yet, but I truly believe this is the perfect piece that I needed to link and run the exact/preferred Set-up I want and prefer to run, on my new Vector. My Vector’s upper is post 2017 & came hingeless but Thanks I didn’t have to settle for my 2nd choice Set-up, I am now squared-away thanks to ya’ll

Thanks Again, (1st purchase of I’m sure of many from you).

As sturdy as you would expect from a piece of plastic

It's great if you don't shoot your vector much, but after 3 range days and 1500 rounds of ammo the mount cracked exactly where you would expect it to when you receive it. Fine for a wall hanger.

Great Product

I have a Gen 2 Vector, I wanted to install a Gen 1 stock which you need an adapter. The product was a good fit and sturdy, it matched up to the stock perfectly and has no play at the gun to adapter or adapter to stock. I did suggest that they replace the oring with a solid spacer to eliminate the oring from bulging at the hinge point. But great product over all

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
