5 Fantastic quality and customer service
Posted by Jay on Nov 22nd 2024
I have 2 of these handstops, and they are functional and lightweight. unfortunately, i overtorqued one of the handstops and stripped the older hex style screws. Customer service was quick to send a replacement screw within 1 week.

After seeing on WPS M4A1, I purchased the Karve-P. It feels and looks amazing. Easy installation and quality is excellent. Have purchased other Railscale products and definitely will buy again, very high quality and durable.

5 Absolutely Perfect

I own pretty much every brand of hand stops, angled Grips and vertical grips. I love this on a 10.5 inch SBR with index finger around it with pull back. GET IT

5 Karve
Posted by BG on Aug 4th 2024
Picked up the karve to run on my Spear Lt 9” so far so good. I like that it’s small and can conceal in the bags. The Karve also doesn’t get hung up like my larger VFGs do. Perfect for truck gun; or for those who like a more low profile forend on their rifles.

5 Karve-Poly
Posted by Ted B on Jul 25th 2024
This small handstop is contoured well, and gives my hand a place to sit where I can press against it comfortably.
