Looking for any length gas tube (MAR preferred) that with integral milled picatinny rail that goes all the way to the dust cover. Rumors that these were produced by IMI and sold by several different companies in 2000-2010s.
Not looking for a welded rail or the Hillbilly version which neither have the rail to the dust cover.
