If you have armalite make sure you call before ordering!! light, great feel, no rails included - Diamondhead VRS T-308H Free Floating Keymod Handguard 13.5 Inch 2362D

So I have an Armalite AR10 and ordered this handguard because there are not many options for those of us with Armalite products, especially the AR10. I had the A-2 style upper with the delta ring and wanted to go free floating. Once I finally received it and tried installing it the barrel nut didn't fit. Optics Planet told me it is not compatible with my rifle - I told them they advertise that it fits the Armalite AR10 and that I shouldn't have my money tied up for weeks because of their error.... So I called Diamondhead and they told me they always ship them out with DPMS barrel nuts, but they have the Armalite threaded nuts available and priority shipped one out to me at no charge. Now it's on my rifle and it looks and feels great! For how expensive it is it should come with at least one rail, as it only has the top rail, although, the smooth, almost triangular shape is very comfortable in the hand without any grips/covers. It also has a proprietary nut that is 1 3/8" I think and does not come with one. Armorer's wrenches do not work on the nut, so plan on looking for a huge wrench to get it on there (I couldn't find anything but a crescent wrench that large).

Overall this product seems built well and looks great, but buyer beware if you have Armalite, call and make sure they ship with the right nut!
