The Umarex UMP is a very reliable AEG. It is ABS with metal rails and a metal gearbox but it does have a nice realistic weight to it. It has a lot of space for attachments because it has a rail on both sides, the bottom, and on the rear of the top for optics. I play CQB so this gun fits this role perfectly because it has pretty decent accuracy although I have played field and it works well but it doesn't have an amazing range. This gun is also extremely strong considering it is plastic because i was running and fell and this gun broke my fall on a rock and didn't even get a scratch and still works perfectly. The only bad thing about this gun is that there aren't any midcap mags available and it doesn't have a threaded barrel.
Really good fire rate
Perfect FPS for CQB
Lots of rail space for multiple attachments
Full metal gearbox is very reliable and works great
My big con is that the barrel is not threaded so you have to buy a threaded barrel if you want to add a suppressor, flashhider, etc.
No midcaps available for this gun. the highcaps work great but a midcap would be more realistic.
