HK Heckler & Koch MP5 K-PDW Semi Automatic .177 Caliber BB Gun Air Rifle

The stock of the gun has undesired movement when locked in place that isn't too bad but is a design flaw that could be fixed, the frame is a durable plastic that's nice in weight along with the magazine that has weights inside for a more real feel, the charging handle is functional but not blowback, there is only one sling attachment point and its located on the front left of the gun but it can be moved by holding a small pin down on the other side and giving a nice tug, you get about 120 rounds out of one co2 cartridge before its power is too weak to pierce a can, overall Its a good gun for target practice but I don't think it could withstand a drop from more than 1ft or 0.308 meters for metric.

The HK (Heckler and Koch) MP5K PDW (Personal Defense Weapon) is a variant of the MP5K introduced in 1991. It is equipped with a side-folding butt stock, a threaded three-lug barrel for attaching suppressors, and is typically fitted with the ambidextrous MP5N trigger group. The side-folding butt stock can be fitted onto any MP5K with no modification to the weapon itself. The PDW has seen only limited usage - mostly with Special Ops groups, aircraft crews, and tank crews. It is very popular with U.S. Special Operations forces who see it as a compromise between a pistol and a full-sized submachine gun.The HK MP5K PDW by Umarex is a product of excellence. I was very impressed with the high quality and pleasing aesthetics of this beautiful crafted and realistic semi-auto BB gun. The gun itself is surprisingly heavy for its size. Very solidly built with no creaks or shimmies. To insert the 12-gram CO2 cartridge you first need to remove the two rear body pins. I did this by pushing the retaining loops into each pin and pushing it through the other side. After you take the pins out, remove the rear stock and insert the CO2. Replace the rear plate on the gun, reinsert the pins, and tighten the CO2 cartridge tab to hear the gun pressurize. The stock folds by lifting the front upwards at the hinge and allowing it to fold to the right and I love how it locks firmly in place in the extended position.The selector switch on this gun moves smoothly between its settings with a solid click at each stop. Click it from Safe to Fire and let out a few shots. I noticed that this gun recoils like the real firearm and has a mildly firm trigger pull that isn't overly heavy or light, it is just right. Trigger response is good and shots were right on target from the start. The magazine is metal that is very solid to the touch and holds 40 steel BBs. The only thing I didn't like about this gun is that it does not have standard rear sights. Instead of four different sized holes in the drum there are four different sizes of rectangular slits cut into the drum. This works fine for CQB (close quarters battle) but long range accuracy suffers. Then again this gun is an MP5K so if you're looking for long range accuracy you're on the wrong horse!The gun does have very nice externals. From the oversized cocking handle to the nicely textured stock, it feels great. The feel of the metal parts is solid, but the appearance is not as good. The metal parts are shinier than the rest of the gun, but that can be remedied by some Krylon ultra flat black spray paint. The magazine release is plastic but feels very sturdy. The plastic on the lower receiver, foregrip, and stock are nicely textured and are a satin black color. The upper receiver is a smooth plastic, but feels sturdy, and is the same color as the lower plastic. It appears that Umarex used a thick, high-quality plastic on this gun. The foregrip feels sturdy with just a slight wobble. The pistol grip is comfortable, nicely textured, and easy to hold on to. I would have no problem going on patrol carrying this gun, but be careful displaying this gun in public it looks totally realistic. Overall this is a well built product that will hold up well for years to come. Buy it!

I've had this thing for about a month now and I really grown to hate it The first one sent to me was a dud. The the plastic pieces fall off in chunks CO2 cartridge tab broke off in my hands the firs the site a terrible I just can't say enough bad things about it I'm really bummed that I purchased this thingt time I tried to twist it. Then it wouldn't buteven turn with plyers so I returned it. The return jprocess could not have just been easier. Amazon sent out the new one even before UPS picked up the broken one. Now that's what I call great customer service.The gun shoots well although the sights are quite off. It doesn't have quite as much power as I wish it had, but still it is pretty darn fun to use, and the folding stock is just plain cool.I've had no issues whatsoever with this second item and I've probably shot it about 250 times in the last two days. It is Los of fun, it looks great and will impress your friends.

To the iconic H&K MP5. Takes 1 CO2 cartridge loaded behind the brace, keeping the slim magazine looking realistic. Mag holds 40 BB's - but take my advice... buy another one (or two). It's quite accurate and a blast in full-auto fun mode. I loved it so much I bought two - one for each residence. Fits in a briefcase - Just sayin'."Now, I have a machine gun".

Leaks Co2 carts! I’ve had some jamming issues! Not so realistic! Shooting ability the trajectory is off! Not happy and I can’t get in contact with seller!UPDATE: returned the gun! Still waiting on my refund!

I used a laser bore scope to set the site, installed the mag full of bb's, then pierced the cartridge and took aim. I pulled that trigger over and over again and just kept sending them down into the target, and once the mag was empty it stopped just like a real gun. This thing was fun! I did this several times and just felt the stress melt away as I unloaded each magazine over and over again. It looks very real, it feels real...it's not all plastic and cheap, and it fires really well. You will not regret buying this!

worked perfect until i spilled silicone all over on it and in it. now, shoots inacurately and cant remove the co2 cart. its a great for practise

This gun is fun to shoot!They need to make a speedloader for this gun, I havn't found one yet. The "40 shots" last a long time if your not just slaming the triger. It will shoot as fast as you can pull the triger, it has a looong triger pull but most bb Co2's do. It has a sweet spot because the triger dosn't need to be let out fully to set the next bb and air charge so IF your good you can fire very fast, I haven't made it jam yet! It's accurate farther than I thought. Great gun for plinking too(main purpose in my opinion). I was shooting over 50 feet.....(a little far for this rifle). I hit somethning the size of softball 2 out of 8 times at that range(hey the others were close lol). I needed to move in 20 feet to see what the gun "has" and have not done so yet but I'm sure it gets even better at the 30 foot range!
