KRISS Vector First Gen Stock Adapter Hinge

Does the job but low quality

Allows you to use the vector stock which is cool but adapter has play in it and not rugged. When using with the stock you can see the adapter flex from pressure.

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
