Sounds like you have a well thought out plan with your new 14.5 build. Vortex has an optic that has been popular with forum members. This is a Vortex PST 2-10x32. The scope has a lighted reticle and can be purchased with mil or MOA reticle/turrets. The low light performance is supposed to be good. I have never purchased this optic as it is a little pricey but supposedly well worth the price. I have several 2.5-10 scopes but mine are heavier and larger but the PST II still has an adjustable objective/parallax. I think the 2-10 magnification has some advantages compared to the LPVO 1-6 or 1-8. This 2-10 will be heavier than a 3X prism optic but would be more versatile.

I have a 12 6.5 Grendel from Rexus which are Green Mountain barrels. I also have two Faxon 6.5 Grendel Logo barrels (16 & 18) made for site administrator BFT. All three barrels are properly gassed and Im using the supplied carbine spring and 3 ounce buffer with each. Unless your going to run a suppressor Id test the 14.5 with a Carbine spring and buffer and see how it performs.
