My two T3x's, finally both have optics on them.
6.5 CM CTR in a Bravo with a Sig Tango 6 4-24x50
308 Lite that I put into the CTR stock with an LRHSi from GAP
The CTR build still needs a sterk bolt handle (gotta order that), and a muzzle brake. A Triad Tactical stock pack is in the mail for the Lite to raise the comb. I'm tall and I prefer a higher comb, rather than stretching way out and being closer to the bolt, hence the higher ring heights.
The CTR has a spring from yodave, and the trigger is fantastic. I am honestly surprised people are looking at the Timney. If something comes out that blows this away... sure, but that would take a lot.
