The L model is 8.9" long, weighs 21.8 lbs and is a 30 caliber rated can.
I'd sincerely suggest looking at the K model Dragoneggs requirements if you're looking at Dead Air for a dedicated .223 can.
The K model is 5.4" long and comes in at 12.8 oz (and is still rated for 30 caliber).
ANYIME I have boys shooting a AR or other centerfire supersonic round using a suppressor, mandatory hearing protection is always used (mine was literally shot decades ago so I'm more careless shooting by myself at times without hearing protection, just being honest). For some reason, people think that 135 decibels is hearing safe, and you can read gun rag or blog writers writing a review informing you that if a supressor comes in at 139 decibles, it's hearing safe. News flash, it's not. That said, a supressor will get more sales if it's deemed "hearing safe" over a suppressor that is not "hearing safe".

Generally speaking, if you can hear the bullet striking a "soft" target (such as a tree or wood) within 100 yards, it's pretty quiet IMO. Anything supersonic I genearlly don't hear the bullet striking.
This is kind of where hollywood has really misled people with suppressors in the movies. Other than using a .22LR subsonic with a suppressor, no centerfire suppressor is "hollywood quiet".
Now, the HUGE advantage IMO is when you're further away from someone using a suppressor on a supersonic centerfire round. World of difference IMO even 10' away from the shooter without hearing protection (no sound concussion at all IMO), let alone the huge difference if you were in a home 200 yards away.
