I was wondering if somebody could help me ID a upper assembly. I didn't notice any markings on the upper reciever, but the barrel is marked B MP HBAR 1/9 5.56mm Since I am not looking at the barrel right now, I may have put the HBAR caliber and twist in the wrong order. It is chrome lined- chamber and bore. The markings I saw are in front of the FSB on the top of the barrel. The FSB will accomadate round A2 handguards or triangle A1 handguards (it has the triangular plug-in). |
