Build Quality: Lots of plastic but it does not feel cheap, the internal mechanical parts and frame appear to be made of out of metals.

The Umarex H&K MP5K PDW 4.5mm BB Replica is a very realistic BB Repeater. It's fun to shoot and seems to have an endless magazine. The Blowback does give it s little bit of recoil when you have a fresh CO2, just don't expect too much.

The outer shell of the gun is mainly made out of plastic but for about $125 you really can't expect an all metal version.

If you're looking for a true Tactical styled BB gun, this would make an excellent choice.
