The Firearm Blog got one of the first looks at the Magpul Handstop Kit and new XTM panels. This kit consists of the handstop component, an enhanced XTM panel (which now features a textured finish), an optional finger nub component, and a short XTM panel with the same texturing. As you can see the kit is extremely simple and works with railed forearms. Users can add or subtract panels as required.
The enhanced XTM panel seen is also indicative of the overall change to the XTM panels Magpul offers.
Price is listed as 19.95, with a release date this Spring.
