The T3 tac is a sweet rifle, these rifles are very good from the factory, and usually very accurate too. They do have a few weak points though and the plastic magazine system is one.
All of the T3's are essentially long actions, those used for the short action cartidges, just have a bolt stop installed.
You'd want to buy the short action one if you're gonna install it you're self.
The CDI bottom metals are of very good quality, the finish is good and they're reasonably priced,I have a few of these on other rifles. As for the T3 i don't have one on it, but i've used a modified T3 quite a lot and the CDI DBM has been working great.
I'd choose CDI if i were you. As if you wanna change to a long action cartidge in the future, or just want more length to seat bullets out in a SA caliber (no issue with the 308). The DBM inlets are identical, CDI is also the only manufacturer that makes T3 Long Action DBM's.
If it was me, and I was going to send the rifle off for inlet, installation and bedding, i'd just get the bolt stop removed and run LA mags any way. That's just my personal opinion though.
I would advice you to change the factory aluminum recoil lug too, when you're first at it. The aluminum is rather soft and will get deformed from recoil over time, even with a low recoil caliber as the 308 win.
If it was mine i'd change the bolt shroud also, it does not affect the function or accuracy, I just don't like plastic parts on a bolt rifle.
) prolly can't get it any lower than that.
