More details please let me know
It is a century imported Imbel receiver. It's not a g1, it is a Steyr FNFAL stg58. It is a hammer forger barrel.I'm not sure about matching numbers. When the barrel was timed it was set between a lower match and upper field grade chambering. British l1a1 mag release (longer). It is a metric receiver and will accept inch and metric mags. Brand new springs throughout rifle. Tapco first generation picatinny rail which was hand fitted. Original stga 58 stock set. I also have a spare piston, and some metal hand guards, and the original bolt. British L1A1 bolt currently installed with sand-cuts and 2 piece firing pin. This rifle has the short gas system. Those 3 alone make it more reliable than an off shelf FAL.
450ish rounds - avalanche defense tactics LLC (colorado) .308 147gr fmj. Brass ammo in ammo can, 90-100 rounds Ball L2A2 ammo. (told it was British surplus) also a bag of russian steel case .308... That's 2 ammo cans worth.
