It’s a handstop- no more, no less - Guntec USA Micro Handstop

This is a very basic, inexpensive way to keep your fingers off of your barrel or suppressor on an SBR. I have 5 now and they fit on SLR, Troy, Griffin, Geissele, and ALG MLok rails. The finish is flat black, gritty and very durable. It reminds me of truck bed liner, which is a good thing. I could not care less if it “matches the finish of my handguard” or not. I believe that functionality should trump looks. As for the price, it’s the least expensive NOT PLASTIC” hand stop I have found. I am all about buying US made stuff, but comparable items on this site cost 2x - 5x more. It’s all I use on SBRs
