RCM,
You know we love you here, so please don't take offense. But those things are uglier than a barrel full of assholes. These conversions are so easy, why anybody would resort to one of those is beyond me.
Folks, RCM is a terrific vendor, who also sells all the parts to do it right (FCG, PG, Buttstock) All you need is a TG. You can even use one of the bolt on types available from tromix or saigatech if you do not want to cut a T-nut opening.
