They make some AWB compliant rifles so email or call them and ask if they'll make a 308 MWS compliant
Short of that, you can probably find an FFL to order one and convert it to AWB compliant before transferring it to you but that would cost extra. Better to ask LMT to do it.
Thanks you for your time replying. I just got a copy of their most recent catalog. I see they have one with a pinned SOPMOD and a target crown barrel. I assume that is the AWB compliant version.
I'm sure this version of the rifle is totally unacceptable to the criminal element. Glad my safety is being watched out for by the MA legislature.
