SBR caliber?

[michael_aos]

I've got an SBR-registered lower, along with a 22LR, 9mm, and 308 suppressors.

I keep looking at 22LR, 9mm, 300 Whisper, 6.8SPC, and regular .223 SBR uppers.

Just can't decide.

Any thoughts one way or another? I've already got several 22's, including the Nordic AR22 conversion. Pretty set on 9mm's, with an Olympic K9GL and M11/nine SMG. Pretty well covered on 16", 18", and 20" AR's in .223.

The 308 suppressor is currently shared between 22BR and 260 Remington.

guy on ar15.com has a bunch of shortened ar bbls he was selling for $125.00 ish to run a .22 conversion.
i ended up cutting down a 20" 1/9 bbl to 7.5" and threading 1/2x28 that i had laying around 2 yrs ago.

6.8SPC or if you reload and have the time to reform, I'd go 300 whisper.
