This question is for the guys with one receiver and several barrels. If you do all the mods to the fore-end, r.t.v, o-ring, etc what happens when you put on another barrel? To clarify: I do all the mods with the 243 bbl attached and get say1/2 inch groups, what will happen if I put on a .45 Colt bbl? Will I have to do all the mods over again? I haven't seen this dis-cuss-ion come up yet.
Inquiring minds want to know.
thanks
Norman
