I am thinking about building a 22 SBR upper. But i am trying to find out what barrel length would work best for me. I would like to have standard velocity ammo stay subsonic. Will a 5.5 barrel keep standard bulk pack subsonic or will i need to go shorter? will there be functioning problems with barrels shorter than 5.5? I want it to run well with or with out the suppressor.

Who is making 22 SBR/pistol uppers? I see a lot of threads that CMMG has them being tested but i don't see them on their web page. Does anyone have any info about where i can get complete 22 pistol uppers?

I run a 5.5" cut down M16 barrel. It runs great and stays subsonic with everything I have put through it. I mainly run federal bulk packs.

Spikes did offer the shorter barrels at one time. You may check with them.

CCI standard velocity stays subsonic out of my 16" AR-22.  I use mini mags out of my 22/45, which is a 4.5", and they stay subsonic.  Hope that helps.

Redtazdog just put a 5.5" 22 upper together for me. Great guy to deal with and knows his stuff. Sent him all the parts and a lil $$ for barrel work, machining of barrel adaptor and other parts and shipping and I am looking forward to shooting it when I return home. He is spoke highly of all over the forum.

I bought a CMMG upper used off of the EE, took the barrel out and it to ADCO to cut down to 5.5"
