I put a KRG Bravo stock and Triggertech trigger on a Remington 700 .223 that had that cheap plastic stock from the factory. It is a stainless action with a varmint weight barrel in 12 twist. The barrel is still shooting well enough but got to thinking about a new barrel to go with the new stock & trigger. How would a pre-fit work with the 700 action or should I go with the gunsmith route and the associated extra cost? This is not a competition gun just the casual paper puncher. I put a WOA barrel on my RPR last week which is another reason I got to thinking about the R700 upgrades. TIA
