Second hand gun question.
 

Im looking at picking up a G&G UMP off of a guy for $130 bucks, with no battery and charger, and sadly I dont have any batteries sitting around to take and check it out with. Is it worth the risk to buy a gun you cant fire off and test?

$130? What's wrong with it?

Go to a local RC shop and pick up a battery. There's no reason to not test it out if you have the chance to.

$130?:eek: Even with messed up internals that's a steal

all signs point to it being cansoft though. which is in the high 300 areas... so it's about what I'd pay if it was messed up, not a real deal.

You are going to have a big headache fixing it if you haven't mastered gearboxes and gun body repairs.

When I got my first gun a TM MP5K for cheaper than $300 I was happy as hell, it was the cheapest I can find and me thinking TM is a good brand which it is but unfortunately as good as a brand can be the owner and the years of use can seriously wear it down especially when the gun has 3 years + mileage on it

If that UMP is really messed you would end up spending upwards to almost as much as a new Cansoft gun would cost

With really really used guns most likely you have to change
- Hop up rubber
- The whole hop up unit if it is mangled beyond repair
- Wiring (If you see eletric tape all over the place, replace it)
- Motor (Its usually about to die, you can even smell it)
- Gearbox internals

Well I went out and got it from the kid, he was heading to university and it woulda been a nono in the dorms, Its less than a year old, got home and first thing I did was do a field strip down on it, all the internals are clean at least, really no wear on the outside or inside of this gun. Going to plug in a battery to it in a few days and we'll see how it turns out. Its new enough that the mags are still a snug fit into the reciever and dont show that they've been used alot.

Sooo...basically you asked for our advice....and then completely ignored it.

I guess he's confident enough to fix it if it has problems. He could always send it to a gun doc too I guess.

I didnt really ignore any of the advice given. I took it all into consideration, and made sure I took a good look over it before purchasing, if it works, for $130 it was a steal, if theres something wrong, the I enjoy projects. Didnt mean to insult anyone by not heeding any warnings etc.
