That would make it subsonic at 1K yards...so in other words, not a 1K capable rifle (regardless of Chandler's claims). It would also give it 60+ inches more drop at 1K yards than a M40.
The Marines make their own M40's for the most part, if they wanted an 18" rifle why wouldn't they just make it in house? The $10K price tag leaves me feeling like this was a good 'ol boy transaction.
