Very nice PB!

Not an expert on the T3...or the T1x by a longshot. I am currently building a T1x chassis gun though (first chassis gun for me and I went a little nuts on this and can't go back..lol), researching what shooters use, I see Mountain Tactical and Area 419 mentioned a lot. I personally went with the Area 419, but it seems that the popular opinion is you can't go wrong with either.
