Really tough decision and question.
I have a handful of LaRue rifles, but not a blind fanboy. I bought two of the build-kit small bore. For large bore, I did not see the business case. I have two LaRue 7.62's and love them.
The issue is plain and simple: The build kits are SHIT for fit and finish, but are great shooters. Some say, "that's fine." But, at the end of the day, LaRue has built its reputation on two axis's: Great, sub-MOA shooters, and nicely designed works of art. Now, I will tell you, that whatever you think of ML, I don't think he will compromise on accuracy and solid material. But, in terms of aesthetic design, his Stealth 2.0 upper i so all good... until it mates with a LaRue lower, and it you might as well buy an Anderson lower, because the upper is angular, vis-a-vis KAC, and the lower is a nice billet work of art.
Bottom line, whilst I will put up with shit on an shingle for small cailber, I am not paying premium prices on the large frame for something that nobody thought out on the design.
