I understand its a cheaper gun but its a clone of the G&G ump which does retail for $300+. So my question is what for the externals is metal? And is the Gearbox in it metal? Also how do V3 gearboxes go for upgrading? Are they prone to breaking or? I did search around and look around for an internal review of it on youtube and couldnt find one. Just curious if anyone could assist me. I do know its a cheaper gun. Also if anyone knows anything of the H&K ump which is also below 200 feel free to answer the same questions above. I understand its a V3 gearbox but it uses a different mag then the G&G style ump. Just curious if its worth spending the extra 40 or 50 dollars to get the H&K version rather then the DE one. The DE one also comes with a laser sight and a red dot which i assume are pretty much useless? Links to the guns im referring too.

The orignal DE Ump i found didnt come with the laser sight and red dot but was out of stock. So i used a different store.
