On my 300blk AR, i started with a AAC 762sdn6 because i wanted max sound reduction. After a bit i changed to a Gemtech 300blk can. Not as quiet but a ton lighter and shorter as well.
I could not be happier with the shorter/lighter can on my 300blk rifle.
The 300blk does not habe anywhere near the gas pressure or volume of a 556 or 308 does, so a smaller can is just fine.
My 9” 300blk WITH the Gemtech can is still shorter then a 16” gun and even with supersonic loads is not horrible, with Subs its a dream.
