Glad to hear it's running smoothly! I'm going to head to my LGS and start inquiring as to what they can get as far as parts.
As for the R700, do it! I love mine to death, 700P in .308, sub 1/2" at 100 alll day long. Plus I'm not a great shot by any means! Just learning
Also that all tac ops rifles are all 700 actions that are sold with sub 1/4 moa guarantees, lots of range reports showing sub 1/16th moa results :O
Although the accutrigger is very nice, I love my .17HMR, beauty trigger. They have some attractive offerings in .308 for great prices to boot.
