Not as depicted - JP Enterprises Tactical Rail Kit Accessories

This rail is not as depicted. I sought this to specifically mount a forearm grip on the free float tube of my Bushmaster XM15 Varmiter Carbine. Both ends have ramps instead of being clean cut notches which, makes the end of the rail useless. My forearm grip has two notches on either end that need to rest in a grove but can't. I'd like to say this is a well built product but since I'll have to machine out full groves in the end before I can use it, I have no idea how it will perform long term.
