I have been trying to get this together for a while and as we all know parts are scarce , I still need a charging handle if anyone has one out there they would like to part with . I have no clue what kind of barrel it is there is no stamping what so ever on it , the FSB is machined and very very smooth , no cast flashing on it , it is a 12" heavy profile barrel , it had a 6" flash hider on it that looked ancient. The barrel is just snugged up as it is going to get bead blasted along with the FSB tomorrow so I can reparkerize it Monday because they had light surface rust and it bothers me
The feed ramps have no marks on them and no carbon in on or around the FSP. the only thing down the barrel was dust . lol . No marks from a BCG going into battery , Im going to say this one has probably never had a round through it if it has it was very little .
Anyone know about that machined FSB ?
