| Hey guys! I bought a RRA AR in 9mm. Is the lower altered in any way where I CANNOT use it with a standard 5.56 upper? |
| I always thought that pistol caliber lower had different mag wells than normal, 5.56/223 lowers. However, I could be wrong, I do not have a pistol caliber AR, but RRA does sell pistol caliber lowers separate from 5.56 lowers, which would make one assume that they are different. Also, try posting in the AR variants forum. |
