I have the following for sale. A First Gen MI 7" 2 piece freefloat rail, all you need is a barrel nut. Comes with all hardware, 2 end trim rings.
In full disclosure-
It has some marks-
And this bolt hole-
Is stripped. It does not affect it's function. I had this on a 7" SBR and only replaced it with a Troy rail, to lighten the rifle. The other 3 screws are perfect.
You might contact MI and see if there is anything to do about it or you could drill it out and tap it for a slightly larger screw or add a heli coil. It never bothered me, never was loose, so I did not mess with it.
It comes with a Magpul AFG, with ribbed and plain insert and 3 Knights rail panels.
$90 shipped, USPS Postal MO only.
You can shoot me a reasonable offer. The worse I can say is no.
Post here first then IM me, NO EMAILS!
