How are you liking the Gemtec M-4?
I currently only have a Sparrow SS and would like another can for 5.56/223.
Most of the reading and talking to others that use cans on 223s sate the report is still quite loud (i.e. hearing protection needed) unless using weak loads and/or going subsonic which would then defeat the purpose of the 223.
A 22 mag through my Sparrow, while much quieter than nonsuppressed still produces a good report (hearing safe) and I can only imagine a suppressed 223 would still have a hearing protection needed report.
I digress, and yes, that is a pig of a pig.
