Propulsion: CO2 x1.

Action: Semi auto blowback.

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.

Available From: The Replica Airguns Store

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 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.

Comments:
The gun is plastic based but seems to be well built and has some weight to it. The design and functionality is well thought out and for the price of under $100 you can't rally ask for much more.

The rate of fire is fairly fast and there is only a small amount of blowback feel probably due to the weight of the gun. The Steel Storm is surprisingly loud, so shooting in a residential neighborhood may not be the best place to empty the two CO2 cartridges! I was able to get around 200 rounds from the dual CO2 cartridges, most of which were shot in full auto 6 round burst mode.

It would have been nice to have the BBs in the pull out magazine but the gravity fed hopper makes more sense feeding into the internal lower 30 round spring fed magazine.

The Umarex Steel Storm Full Auto CO2 BB Gun is very fun to shoot and is well worth the small amount of cost. So go get one!
