I have an older t3 model in 260, and just picked up a new SS t3x in 6.5cm from whittakers. Both 20". Haven't shot the 6.5 yet, hopefully will tomorrow. The 260 shoots great, I expect the creed will also.
I like the new t3x stock. Nice vertical grip with good texture.
Magazines are nice, double stack so even the 10s aren't that long. Mag release doesn't hang below. 2.9"ish coal latitude. I'm fairly sure you can get 5 rounders now also, would be shorter. $115 each, kinda spendy but how many do you need?
I agree with josh, 20" if you're going to run a can or just want a handy rig.
Very good rifle for $1000 IMO
