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.
Realism: Even though there is a lot of plastic this is a 1 to 1 scale replica with full H&K licensing. It is a very accurate replica of the original.

Pros:

• Being able to own an H&K MP5 for just over $100
• High capacity 40 round magazine
• Blowback action gives some feedback
• Very nice folding stock

Cons:

• Does not come with picatinny rail adapter for Red Dot or scope accessory
• Blowback does not operate action
• Mainly plastic
• CO2 hard to get to

Comments: 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 a 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.
