Hi. My first post here.

I want to have my MKII barrel shortened to 16.25" and threaded to accept my Liberty Shoofly suppressor. My rifle has the Accutrigger.

I need to ship only the barrel and receiver to the shop - no trigger group or bolt. I've stripped the rifle down so that only the trigger group remains on the receiver. How do I remove it?

It seems to only be attached where the Accutrigger adjustment is pinned into the receiver.

TIA.
