睇段片, 5:50主持拎把m4換左個upper receiver
所以我就說我不知這個算是成槍還是kit...
I wouldn't call it a conversion kit cuz I think you will need to change the barrel for .50. I got a .22 conversion kit and here is how it looks like. It's just the bolt and the magazine. Basically .223 and .22 can share the same barrel. That's why you can just replace the bolt and mag with this kit, and you are ready to go.
