    Well made, ultra light weight and very functional. Everything you want in a hand stop with the functionality of the rail scales for additional grip and heat protection.

    I would have dropped the rating a star for the price/cost but the quality, material, and precision manufacturing easily gets an extra few stars. The fitment with XOS-H rail and how solid everything feels remarkable.

    The Karve is the best forward control piece on the market. It’s slim enough to not get snagged and provides the perfect about of stabilization and indexing. Very happy with this product.

    RailScale’s billet aluminum Karve is a functional addition to any modern rifle. Its ingenious cog mounting system allows either M-LOK & KeyMod installs. Flawless fit with any XOS-H, PMM REP-LOK lower rail, or M-LOK handguard . Excellent stability control & barricade stop. I would recommend for any rifle upgrade.

    Less is more

    This hand stop/grip/ finger groove is simply the best. I prefer a clamping grip, I have found that most stops are still too present. This gives me the grip I like and does not interfere with the feel of the hand guard itself.
