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


Would consider trades for, 


8in 300aac blackout, various MP5s, AK47, or will listed to others.
