Both the lower and uppers are larger than the 5.56 units. The LMT MWS is a nice rifle, but it's heavy weight and $3000 price tag will likely eliminate it from consideration.

Armalite's previous magazines eliminated it from my consideration, but they now seem to use PMAGs. They are likely at the more affordable end of the complete rifle spectrum.

Two other somewhat reasonably priced rifle manufacturers are Fulton Armory and DPMS. I have no experience with Fulton, but know they follow the DPMS pattern. I've owned my DPMS LR-308C (heavily modded) for 8 years, and it's been very reliable and accurate. I assembled the lower, and any parts that were proprietary, like the pivot pins, were easily purchased from DPMS. I bought the upper as a complete assembly.

If I were to get another, I'd likely assemble one from scratch using Mega MATEN stripped receivers.
