I have read everything at ammo-oracle that partains to this discussion...I know the differences between the rounds, but what I don't know is..

Are Bushmaster rifles all 5.56 or all .223?  The one I am interested in is a 20" A3 no-ban.
This is what the website calls it: Bushmaster 20" A3 Heavy Bbl .223 Rifle
And this item number:  Bush-BCWA3S20  A3 Type
But, in the discription it says:  Semi-Auto 5.56mm-.223 Rem. Caliber.

So, is it 5.56 or is it .223?

Thanks, I'm a newb...

5.56
and they are awsome

almost all of bushy's guns are 5.56 (like 99.999999999999% of em), so they will shoot both well

Bushy Varminter is not 5.56. It is .223. The Varmint Special is .223 as well.

Every Bushy except the DCM or Varmint models will be 5.56.

I think the bullpup is also .223, which always struck me as odd
