2 mounts broke within a month

Per the title, I had 2 of the hinge adapters break within a month of each other. On the second photo, I literally shot 3 rounds and it snapped in half and the other photo I shot for a while and the pin ear broke. They sent me a 3rd one but the pin holes are too big. The stock moves and wobbles around. I love the idea of this adapter but it just needs to be heavier duty material and design. The customer service was great at sending replacements out but couldn't give an answer on how to render this issue. They said that they might re design it again, but don't know when that will be.

Hey MD, Thanks for the honest feedback - I have sent you an email directly regarding this.

Kriss vector adapter

The adapter fits perfectly! Looks amazing, when you shoot the vector it feels a bit unstable but works just fine and has not been damaged.

Fantastic Product, Best Product Support in the Industry!

I want to thank Ben for being a stand-up guy! I encountered a minor fitment issue with the KRISS Stock Adapter Hinge. Ben took the time to send me a replacement after he made some dimensional adjustments. I thanked Ben for the replacement, and he asked me to let him know how it worked. That version of the part was closer, but not quite there. I emailed some images of that part and Ben sent me out another after he finessed the design. I got in a few days! That part was right on the money! Dead solid perfect!

It may seem like a lot of work for a customer to go through, but the effort it took me to send a couple emails and to test fit the replacements was minimal. When I consider how other companies I have purchased parts from have either blown me off or have taken weeks to respond to get me a replacement and/or a refund, the Spartan Mounts customer service experience was a joy! I love to work on my guns and to have the chance to work with a manufacturer to improve a product is always welcomed.

In the end, my SBR'd KRISS Vector with a KRISS folding stock is what I wanted it to be from the start. Thanks again to Ben and Spartan Mounts for a first-class experience from start to end. This will, however, not be the end of my Spartan Mounts journey. I will be getting more gear from Spartan Mounts give them my highest recommendation.

Hinge fit perfectly. Thank you Spartan Mounts!


Just works

Great product

Very happy with how I can use the gen 1 stock for my gen 2 vector. Easy to install


Well it was perfect till the mount broke on me about 2-3 months later. And when I first got it, they told me that if it ever breaks, they would send me another one for free And I've emailed the company two times now and haven't heard anything still.
