Boneyard JG M4A1 or AGM 614 RIS

Ok before OP:freedom i want to buy an m4 style weapon. I found these two guns and was wondering if there even worth fixing up. The JG m4 has a stripped Gearbox and the AGM's lower reciever is broken. Should i buy one of these guns? or im I waisting my time buying a horrible gun that will break even if i fix it?

The question is : Can you repair a Gearbox yourself? If you take it to a pro, It will cost 40 bucks just to open up the gearbox, then any parts needed. I would just go to Airdog and PU a new one. I think they are around 150 bucks new with battery and mag.
Also, you get to NOT pay shipping. Thats always a plus. There is nothing wrong with AGM or JG as long as you take care of it and maintain it properly it should last a while.

I would just buy a new JG M4A1 since they're relativly cheap brand new and with buying that gun you could end up putting $100 into it just to get it work good

I agree, I would buy a new one for less and the GB, motor, piston, gears, and all the other internals will have no use. The used would have a ton of use for it to be broken, don't forget that JG's last a long time.

AA has a JG M4 for $120
