SKU:
In Stock
$ 224.99
Guarantee

Total: $224.99

Type: BB Rifle
Manufacturer: Umarex
Model: H&K MP5K PDW
Materials: Metal and Polymer
Weight: 1088 g (2.4 lb)
Barrel: 9.75 Inches, Smoothbore
Power Source: CO2
Action: Semi-Automatic, Blowback
Ammo Type: Steel BBs 4.5mm
Ammo Capacity: 40 Rounds
FPS: 400

Trigger Pull: Long and hard (trigger actuates the barrel forward allowing a BB to load and then snapping back to activate the CO2 release).
Accuracy: Medium to good.
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.

Cool factor 1000

This gun is pure fun. A must-have for any collector. I'd recommend buying the MP5 Picatinny rail to go with it.

Shot a TV from close range

I shot a TV from fairly close range and it shattered the glass put a hole almost all the way through it. This was from about 10 feet away from it. Knarly gun would highly recommend very powerful and built to last and is also a lot of fun. There's nothing I dislike about this weapon. Good for practice from close and far range. I'm not exactly sure how accurate it is from a very far distance but from a closer range it will leave you impressed with its accuracy. I shot aiming down sight in one position towards the tv and it lined up in the exact same spot there was no damage noticeable other then the gaping hole it put in this television. I will definitely continue to buy from this site the prices are fair considering I looked around and this is the cheapest prices around atleast in canada. 5 stars hands down. Thanks replica airguns it was a pleasure doing business with you on multiple occasions.

Good little air unit

Used for years with no problems. It has just now developed a co2 leak. Fixable I would imagine Accurate, dependable, used for chasing bears out of my yard for years. At 400 fps it gives out just enough velocity as a deterrent for unwanted bears and such by delivering a mild sting to the rear end without injuring the animals. In my experience the gun is very accurate at 25 yards and more. Cons are... Magazine spring load can eject all 40 rounds if the release button on bottom of magazine is depressed accidentally when not inserted. The co2 bottles are hard to load and activate and the pins at the rear that let you access that system are hard to remove. Well worth the money in my opinion.

Extremely Accurate!!!

This thing is exceptional. It is singlehandedly the most accurate bb gun I've ever owned to date (maybe with the exception of my Daisy lever action repeater). It can put down a tight 2.5 inch group from roughly 30 feet away, and I never have to worry about shooting up my Dad's wall when trying to hit cans in the hallway.

Umarex HK MP5 K-PDW CO2 Blowback Steel BB Submachine Gun: XLNT Training weapon

Purchased for realistic CQB training, and it fills-the-bill !! Look and feel is XNLT, recoil is nice. Metal would've been nicer, but the fact that you get look and feel close-to-actual for training is worth it, (and it makes the gun less expensive). CO2 loading is a little time-consuming, but not a deterrent. Rounded out our kit with extra mags, top rail, illuminated multi-reticle reflex site, laser, entry flashlight, and sling. NOTE on mags,.....don't recommend storing mags loaded, as it seems to cause spring compression which can affect feeding while firing. Storing mags empty until ready to train we found works best to prevent feed issues, (keeps the springs relaxed until compressed.
