Thinking of trading my M4A1 block 1 sopmod clone build. DD barreled upper with KAC RAS rail system. Lower is a Nodak Colt M4A1 clone lower with KAK lower parts kit. Only run about 50rds through it to get it zeroed and has sat since.


Would consider trades for, 


8in 300aac blackout, various MP5s, AK47, or ammo I can use.
