I have the Fire Control and did the same stuff.  I replaced the lock knob with something better from McMaster.  "Bedded" the rack gear to the base, so on and so forth.  It went from being decent, to pretty good.  I wish it was shorter, because when you fit a regular BR bag to it, it's too tall.  It's worked well enough for me at club level shooting, considering the price.
				
			ridgeway said:I did have a Caldwell firecontrol coaxial when it first came out. Quality wise, it was cheap, but not bad for plinking and hunting guns. I tore mine all apart, deburred and greased the internals to make it smoother. I still see guys using them with modified tops to accommodate 3" bags and shoot well with them.
