freedom fighter......i used a wood called white oak for the tang going into the receiver....white oak is 'pound for pound' as strong as steel......and it seems to hold quite well......i fabricated a slot into the lower handguard and glued in the tang.....it was easier to align it that way.......also.....to make the lower foregrip handle stronger i put in a tensioned rod (nut and bolt) inside the whole length of the handle...
