RWA160B .308 Winchester/7.62 NATO or 6.5 Creedmore Upper?

[Ustauk]

Would the operating system from the RWA180-B be robust enough to handle the larger .308 Wincester/7.62 NATO or 6.5 Creedmore rounds? Would there be a market for a short-stroke piston upper made to fit one of the AR-10-"like" non-restricted lowers available in Canada? Or would people rather just go for the existing DI uppers or get a RWA180-B Grendel? Or would it be too cost-prohibitive to design and test a "RWA160-B" upper? Just a thought experiment

There's nothing inherent to the design that would prevent it from being upscaled to .308. Fitting it to an AR-10 style lower would require a redesign, as well as upsizing it however.

Probably not cost effective though. There's a market for 180B style stuff due to the NR status vs the AR-15. With the NR Ar-10 market, there's more established manufacturers, and going with something unique (and not parts interchangeable) means you're a niche product and limit your sales volume.
