5 Solid build quality

Debated on this as the cheaper option but after putting it on and training with it have, I have no concerns. Solid option if you’re on a limited budget.

This is the nicest hand stop I've used so far. It puts your hand in good placement. It also allows for a good finger forward grip which I like. It allows you to have better control and precision over the rifle. I would like to try the aluminum version as well but this is a great option for any serious shooter.

Well made. Does as advertised. Can’t really say much more then maybe it’s worth $19.99. Maybe even less.

5 Works great
Posted by Steven T Robinette on Feb 2nd 2021
I really like the shape of this one over all the others that I have owned. The angle & curvature are just the right amount for me. I also love the grip texture on both sides. So I can get a good solid grip even whether I decide to place a finger in the front or the back of it. Most of the competition didn't even consider that. Great product.

5 Great product

I bought this after reading about them. Never heard of railscales before. So overall, its very sturdy and well made. Large enough to really stop my hand from sliding back. Fits my midwest G4M mlok rail perfectly.
