I'm really not a precision shooter, but the advantages of these rifles for certain types of shooting is clear, and the use case is solid.
I was/am a fan of Noveske based on their culture and commitment. However, in this case, for this type of rifle I'd probably go with Seekins. KAC is on the radar too. I've been considering a purchase, but it's currently on the back burner because I have two SCAR17s that are filling my use case adequately for now. I'm also trying to decide caliber; .308 vs. 6.5 (or adding 6mm ARC). And I have thousands of rounds of .308 generic M80 and a generous portion of FGMM I've been buying for years. Also, I know how the SCAR platform will perform, so switching is more complex than just picking one.
The main reason the Seekins is attractive to me is CS support and ease of suppression. The SCAR is horrible to get suppressed reliably IMHO.
