My "dream" AR-308 would be a 16" LMT MWS-based gun, but those are pretty expensive. And super hard to find even in good times.
So I've been looking at building an M5. Good idea on paper, but good luck getting all of the components to pull it off right now. Should have done it a year ago, as it stands I'm not going to mash F5 hoping parts come in stock or paying crazy scalper premiums. At least I have a design to work from should things get better.
Out of the box, the Sig 716i Tread is a compelling offering and I'd give those a serious look. Haven't seen any in a long time though.
Stag Arms has completed their move and is starting production again. Seems like they're starting with restricted state Stag-10 models but hopefully they'll get back into the free states before long. Those are definitely underserved markets so I can understand why they'd target them first. I remember the good ol' days when Stag was one of the best choices for rolling your own. Hopefully the new Stag Arms can recapture that legacy.
Springfield has their .308 AR line as well; politics aside, their product line confuses me and I'm not a fan of the styling. Marketing for them is kinda dumb too. Should just stick to their OTHER .308 product but ARs are/were a license to print money.
PSA has been through so many generations on their design that I quit following them. Probably a great value like all things PSA. Used to have a lot more choice in their offerings compared to my visit to their site this morning. Yay 2020/2021.
I'd love to see IWI introduce a .308 Zion AR, their .223 Zion is a great design with solid value. If Springfield can compete with their own products, IWI should too.
If they priced it below where the Galil .308 and Tavor 7 sit, it wouldn't cannibilize their markets too badly. Buyers of this stuff are either (1) locked into a price point, (2) like buying anything/everything from a manufacturer, or (3) support diversity in the gun safe where having a .308 bullpup, .308 AR, and .308 AK is just an awesome choice to have. I fit in categories 2 and 3 there, so I hope they do it.
