Looking harder at Windham or White Oak. Already dealing with a Bartelin that is refusing to behave on my 300. Hearing Bartelin is having problems, which would fit my situation right now.
What's the problem with the Bartlien?
Just my POV, but I'd have a hard time justifying a Bartlien on a 300.
As for PSA, don't know how long ago you had any of their stuff, but they've definitely upped their game over the last 3 years or so...........they're using a lot of FN chrome lined barrels which are very good barrels for something not stainless. And they're offering some options with top shelf parts. FN generally gets their gas ports sized right.
For the most part, I usually build, & tend toward high end parts, but we've bought 3 of their P&W'ed 14.7" uppers, 2 with Geiselle rails, one with their rail, & all 3 have been dead solid perfect in performance with all the accuracy you can use with a red dot sight.
Here's a pic of one of them with the Geiselle rail.
