LMT's MWS or LM8. Both are 7.62 MRP rifles, and both accept the common and affordable SR-25 type .308 mags, such as those that Magpul makes. For that reason I'd recommend avoiding any .308 AR that uses only the maker's proprietary mags.
I have the LM8 and can run it with either the 16" C/L barrel or the 18" SS SPR barrel. I run both set-ups suppressed.
Theoretically, the LM8 is a bit lighter due to the omission of rails on the forend at the 3, 6, and 9-o'clock points. But you have the option to add modular railage as needed, say, for a bipod, light, or foregrip.
The Brits adopted the MWS after extensive field trials involving a number of different 7.62 gas guns.
