IWI Licensed TAVOR TAR-21 Airsoft AEG Rifle by Umarex w/ Metal Gearbox (Color: Black / Competition Series)

"PROS:
Compact
Accurate
Decent for CQB
Metal Gearbox for better durability
Somehow able to hold a nunchuck 9.6v 1200 battery
Great Battery space
Quick change spring system
Should be able to upgrade all the parts of the gearbox

CONS:
Rear Heavy as expected
Made from Polymer but does have some ABS plastic
Terrible Rate of Fire
Confusing Rear iron sight
Long trigger pull

Overall: Decent gun BUT if you are planning to spam the ABSOLUTE LIFE out of this gun, do upgrade it. I've had this thing's gearbox lock up on me way too much. The Durability I would say is pretty good. I slammed into a couple of wooden walls and it just got some of the paint scraped off despite the handguard being plastic instead of polymer.

"i bought this gun a few months ago and i liked it for the most part but i decided to go back to my old gun because this one is sort of heavy with the metal hand guard and overall it is just heavy. magazine compartment fit all of my m4 mags. the bolt worked.i was able to fit a nunchuck style battery but it was tight and the range is good with the hop-up adjusted correctly. the barrel extinction didn't really help that much it just added weight.

"Does this fit a "weaver and dovetail mount" reddot sight?

"I finally got the gun to work so now I feel I can write a review. This gun is awful! It worked for a solid hour and a half then stopped working all together. Hoping it was a small issue I opened the gearbox up to find the problem. The motor was missing teeth, there were spring missing, the gears didn't line up or sit right, and the air seal was awful. I have spent about a month working on this to try to get it to function again, and now that it shoots again I get about 7 feet out of it. I am very disappointed with the gun, and would recommend you steer clear of this one.
