Coastal suppressor came with 1974 m11 380 is unfired

[deadeye99]

I recently purchased an M11 from 1974. It has very little wear and signs of use. It came with a coastal listed as M380 on the paperwork. It has a steel tube, 8.5” long. 1.7” diameter. Aluminum washers and spacers. It’s unfired as far as I can tell. I did a search and read back to the early 2000’s on this forum and learned that some people love these and some people hate them. Any insight on this is appreciated from the knowledgeable members. Thank you. Bob

They were cheap cans, but had alot of volume and generally sounded pretty decent. Their earlier cans were just washers with spacers. They revamped around 2010 and upgraded to K baffles
