Sadly with how things have been going I have taken a permanent hiatus on buying LaRue rifles. I have a 556 lower and a 762 lower that will never get uppers at this point with the UU kits no longer available. Probably going to post them on the EE. Also have a 14.5 p/w Stealth barrel that needs to have it's barrel extension retorqued and can't find anyone in my AO anymore that can do it.
For my currant 556 I bought Wilson Combat lightweight billet receivers, a fluted Wilson Recon barrel, and Wilson trigger along with their slab side new BCG. Awesome rifle and the parts all came with the colors I selected through their store.
I was considering selling it and getting a 556 tAR but now the tAR doesn't even come with the original barrel profile that made it attractive to me in the first place. I stopped using Instagram so I have no clue what Mark is up to these days but I can only say I'm disappointed. Especially considering I can put together a matching 762 from Wilson and both rifles end up coming in below 2k a piece including adjustable SLR blocks. No Siete either. Man I was amped up about that rifle too.
