4 Clever Design!
Posted by Luke Karwacinski on Nov 19th 2025
I would have certainly preferred it to be made from anodized aluminum, but this grip is aesthetically pleasing and functional!

Highly recommend having this on any AR platform. It gives you a perfect place to index your support hand.

5 Exactly What I'm Looking For!!!
Posted by Tyler Elkins on Oct 16th 2025
So I purchased this plus 3 of the Dragon Scales for my BCM 11.5 AR Pistol & it completely changes the aesthetics of the gun (in a good way). I got everything in polymer but I'm thinking about going w/ the aluminum for my Daniel Defense!!!! If I could give the Hand Stop more than 5 Stars I would but, RaleScales has def. got a new customer in me for all my future AR Builds...

5 Great affordable handstop
Posted by Cody Brown on Aug 10th 2025
By far my favorite handstop on the market and a more affordable alternative to the expensive aluminum one. But you get what you pay for.

5 Karve P
Posted by Ryan on Aug 2nd 2025
Very comfortable to use, especially when paired with htp-xos panels it is excellent heat mitigation and is my favorite combo. I have no complaints after 6 months of hard use.

5 Absolutely THE best minimalist stop on the market
Posted by Eric aka 769xThreeNine on Jun 26th 2025
I have... no B.S 8 of these in various colors and 2 of their metal ones in bronze. Don't let the polymer vs their metal variant get into your head, I have both and they hold up under just as much hard use on barricade shooting and hard recoil while weighing literally almost nothing in comparison... good luck getting another company to give you that promise and a track record of actually doing it. These are so cleanly designed and minimalistic that they are just simply perfect and at a price that makes them one of if not the most competitive "made-in-usa" products on the market at $28 shipped! with ZERO checkout surprises like high priced flat rate shipping fees magically appearing in your cart like other brands or retailer's would pull on you. I love that these function in either direction as either a hand stop to pull into your shoulder or turn it around and put it on the muzzle end of your handguard for a rail stop/barricade stop to keep from sliding off your handguard into your screaming hot supressor or worse the muzzle. I have these on 2 300 black builds, 2 sbr'd akm 47s , a jim fuller built 74 style side folder , nexus evo, my wifes new kuna that I keep stealing when shes not around , supressed sp5 home defense gun... and the shotguns... a mossberg 590, Beretta 1301, Beretta a300 (the wife's shotgun) . Also running railscales panels on most with a few Rsb-P on some builds as well. I've tried and have a very large literal drawer FULL of handstops, angled grips , vertical grips in both stubby and longs ... rail panels by darn near every maker there is.. out of all of them I can honestly recommend Railscales as the top , yes their panels are expensive but if you want grip G10 is 200x polymer. If I didnt fully trust them I wouldn't keep buyin all their products PERIOD. Full disclosure if you want/need a lil more meat for your palm and a less minimalistic approach (and dont like the funky clunky look of a emissary mini) the driven arms Shortstop is my other go to (mostly on larger caliber or heavier builds like my scar 308)
