I have the original JM pro and unlike the typical response, I loved mine. I bought all the upgrades that OR3GUN made for it and installed a longer Nordic mag tube and she ran like a raped ape. Seemed like they were really hit or miss on QC which is the biggest issue. Most people never owned one and some owned one and got a bad one. Get the OR stuff and you should be fine. Mine never let me down! Sent from my iPhone using Tapatalk
