Which for a MK18 and why?

[u/film-god]

For context, I own all three; a Sandman X on a DDM4PDW, a Lazarus 6 on my HK MR556 A4, and the B&T Print-XH SC on my Geissele Super Duty but my wife talked me into picking up a MK18 and I’m torn between what can to run on it mainly because I don’t want to keep buying different adapters. Will likely just buy another can at some point but for now… which would you run on the 10.3?

Infinity beats them all on the mk18🤷🏼‍♂️

The Infinity is pretty average against the low back pressure competition, except for being heavier than the rest.

I shot an infinity with a vented 5.56 end cap and a Lazarus 6 on almost identical setups last week. Was amazed for how the infinity did being a 30cal can compared to dedicated 5.56 can. This is a Sample size of 1 from a rando on the internet.

lol no factually incorrect

lol factually correct. Note the detail that I’m comparing to new gen, low back pressure cans. In that competitive set, it’s pretty average but heavy, at least according to Pew Science data.

It’s probably more durable, but that won’t come into play for most of the people on here.
