had quick look there's few thing i don't like but could be wrong blast directed towards ground kicking up dust, not sure how much noise comeback.
have a look on this thread http://www.ballisticstudies.com/Resources/Discussion+Forums/x_forum/17/thread/11916.html
Chris has given up on the shield from what i know but he is using the muzzle brake with great success.
the ports are angled 15 degrees fowards so the shooter plus bystanders don't get blasted.
think Chris had it made and the guy that made it is just starting off based in blenhiem, if its of any interest ill try track down some info for you
