Price is shipped w/ 1 mag The mag is a co2 mag that shoots very hot about 500 FPS KWA LM4 GBB airsoft gun , Magpul. Condition is Used. Has double feeding issue. Sometimes it double feeds. I put the bolt from another lm4 I have in it and it fixed the double feeding. I don’t know what part on the bolt needs to be changed or if it needs a whole new bolt. I think a new bolt is like $25 Also when it double feeds it bends the hop up tensioner and it looses hop up. Top picatiny rail is very slightly loose. Not enough to do anything.
