I've decoded 100% now going to go sbr ar15. I am mainly going to use this lower for my belt fed 22 which I plan to cut the barrel down on. I am having difficulty decidin what barrel length to go with. I l also get a 223 upper for it eventually so that should be effective to. So like...10" or 7" 11??

I personally wouldn't go below 10.5" or the velocities go to complete ****.

So the 7" might be where it's at for me then...

Is that a concern for shooting no further than 100 yards? I'm no into match shooting with this. Only paper punching

If I had to choose I would go with a 12.5" barrel.

I have a 10.5" SBR that is reliable and can hit the 380 yard gongs at the range all day with the Eotech.
If I were to do it again I think I would the the Colt Commando 11.5" barrel.

Best of luck and enjoy!

I also would not go below 10.5". Velocity and reliability will go down, muzzle blast will go up. I have a 10.5" M16, and it's not much fun shooting without the suppressor due to muzzle blast. You may consider 12.5".

hm, i was kind of leaning towards modeling mine after this:

so far as possibly just buying that upper assembly

but 10.5 might be good as well..
