1. Brief History, Background, and different Variants


The MP5 was first introduced by Heckler & Koch in 1966, under the name HK54. This comes from H&K's old numbering system; "5" means Submachine Gun" and the "4" means 9X19mm (which is the ammunition it fires). This gun was designed in Western Germany to be equipped with the police and its border guards. It was called the Maschinenpistole 5 (Machine Pistol 5) or (mp5) in 1966. Soon after, this new gun was given out to all the western anti-terrorist groups of Germany. Nowaday's there are over 25 versions of the mp5 and are used all over the world, especially for anti-terror units and groups. Most retail for about $900.00 USD.

2. Ordering/first impressions:
Well first of all, I didn’t really order the gun. I got it from Dick's Sporting Goods. Now lots of people slam the guns that they have there, but this gun is the only exception to this. Now, I am a CQB player, and the max range I shoot at is only about 60-80 feet max. I heard that the Cm027 had an aluminum barrel causing bad accuracy. This gun has a nice brass barrel so I figured that it would be more accurate. I also treat my guns with a lot of respect and care, so I decided to be different and try this gun out and man, did it pay off in the long run!!! Keep in mind that this gun is a re-branded Well R5 / UTG mp5



3. Appearance/Feel
Well, when I first got home, I was extremely anxious about how the gun would perform, so I immediately opened the box as fast as I could.

Outside of the box that it came in.



The backside of the box (nothing special, just explains features)



Now we go inside the box!!! Pure Styrofoam!

What this bad boy comes with:


-r74 mp5
-525 high-capacity magazine (I'll get to this later)
-BFN 8.4b 1100 MAH Battery
-wall charger (300mA output)
-Bottle of 500 Crosman .20 gram bb's.
-Cheap black sling.
-Small Allen Wrench for motor adjustment and whatnot.
-Un-jamming rod.


This gun is about average when it comes to weight. This weights about 3.25 pounds by itself and about 4 pounds fully loaded. Of all metal pats, about 80% of the metal is on the internals and 20% of the metal is on the externals. The plastic on the r74 is VERY well built, sturdy, and thick.


Please note that this is the Well r-5, not the Well r-5E (tactical version). It doesn't hold a flashlight in foregrip.


Metal Parts On Gun:


-Stock (except for the butt).
-Cocking handle.
-Trigger.
-Sling mounts.
-Selector switch.
-Pins/screws.
-Motor plate (under hand grip).

Opened all the way, GOSH! look at all that grease/lube!!!



Magazine well

APPEARANCE:
The appearance of this gun is great! it looks very realistic and I was comparing real mp5 to it and it was just like it except for trademarks and the selector switch. This gun looks extremely cool from a distance. These kids with these cheap Springer shotguns and m-16's came walking by, so I asked them of they wanted to have a war. They took one look at my gun and chickened out, lol.


FEEL:
If it weren’t for the plastic on this gun, then it would probably feel just like a real mp5. It has a great stock butt and grip on it. It feels very comfortable while blasting at enemies! The fake cocking bolt also adds some realism and is fun to play with (DO NOT H&K slap the cocking bolt, it will fall off eventually).


4. Build/Quality
First of all, ill start with the gun it’s self. I would say that the build quality of this gun is amazing so far. It has no weak spots and the weight is evenly distributed through the gun. The selector switch is a killer though. It barely clicks into semi-auto, and doesn’t even click into full-auto; you just have to line it up without hearing the click.

Selector (sorry for blurriness)

Now for the battery. It is a 8.4v 1100mAh battery that gives the gun a sold rate of about 15 rounds per second. the battery lasts about 2,000 shots on a full charge which is pretty darn good! The wiring is about the same than the UTG one it seems. The battery is also really easy to get into the fore grip after a few times of doing it. After rewiring it and all of that fun stuff, it should last longer now. Here are some pictures of the wiring and battery.

Close view

The trademarks are your typical Chinese gun trademarks. On one side it says "MADE IN CHINA" and the other side says "WARNING, before use read owners manual available from Crosman Corp. E. Bloomfield, NY 144443 US" The trademarks are far off from the real gun. It has the crosman symbol right in front of the stock, the "PULSE R74" and the "6mm BB" trademarks on both sides of the gun.

Left side trademarks, I would have taken one from the other side, but the writing is way too small to capture.

Now for the Stock. The stock is a metal stock, but with a rugged plastic butt. it easily clicks into each of its 3 positions (as shown below). The stock has some wobble, but not much. I haven't used it that much, so I don’t' know if it has the problems that the cm027 have. All in all it's a good and comfortable stock that should last you a while. My Well r8 stock fits perfectly on this gun, so I use that also as a mp5a4 model (I'll have a picture on that later)

The stock

Can't lose these parts!!!

Now onto the good old magazine. I love this magazine. It holds right about 520 rounds (counted) in its reservoir and holds about 30 rounds in its actual tube. This magazine uses the winding mechanism. It's really nice not having to worry about reloading during battles since your magazine holds over 500 rounds!!! Not only does it hold 500 rounds, it feeds great also. What Crosman did was remove the fake bullets, and make that section into another reservoir to hold even more BBs. Most people say that they never feed at all and that they suck, but I have no idea where they got that from. The magazine fits perfectly into the well and has very minor wobble. The magazine has two different reservoirs, one on each side of the magazine. The magazine is plastic, but once again, it's good plastic. The bottom magazine holder, however, is metal. When you remove it, only 4 BBs fall out or 3 will and 1 will stay in the breach.

The top of the magazine

The gun sights on this gun are your average plastic ones that firmly click into each of its four positions. There is nothing else to really mention about them other than they are easy to adjust and are well built, as said above.

Off the gun

Last but not least is the hop-up. Now, I have never had a UTG mp5, so I don’t know what the major hop-up flaw was. I am sure that this gun doesn't have it though because it works great and is very responsive. I heard that the UTG one was weak and reset itself after firing full auto for a few seconds. So I decided to see if this was the case in this gun also. I loaded about 100 bbs into the magazine and set the hop-up a quarter of the way up, and just fired them out on full auto. After I was done with that, I realized the hop-up didn't move one bit and was still working fine! If I ever take the gun apart, then I will get some pictures of the internals. There most likely to be like the UTG internals though.

OVERALL: The build quality is pretty sturdy and firm. I have not had any problems with it yet, as well as all the components listed above. takedown is just like the regular mp5 Marui models. The only problem is that the wires are glued onto the motar from the gearbox, so you have to actually cut the wires off, then when your done modifying or wiring the gun or whatever, use wire stripers and glue them back on. A real pain the the arse. My dad did this part for me. Luckly he has a degree in electronics. If anyone needs a takedown guide for the mp5, visit www.mechbox.com and look for the mp5 takedown guide.



5. Performance
This is my favorite part of the review. First of all, I charged my battery for 6 hours (max. charging time), then I took it outside to see what it could do. I loaded some High Grade KSC .20 Gram bb's into the magazine, plugged in the battery, measured the target distances, then began. It was the perfect day to do this because it was about 70 degrees out with no wind or gusts at all (if not then 1mph).

So here's how it went



20 FT. SEMI-AUTO.



40 FT. SEMI-AUTO.



70 FT. SEMI-AUTO.



30 FT. FULL AUTO 5 SECONDS (as you can see, my sights were pointed a little bit to the right).



Shooting at about 10 ft (the shots were to the upper left hand of the black box)



This is a ROF video, the camera was held next to the gun in this video.



Poor Mans Chrono Test



.20 Gram enter



.20 Gram exit. It's hard to see, it didn't really exit, but it left a monsterous dent!

As you can see, the accuracy is awesome. The stock affective range is about 80-100 ft. With all of my modifications, it is now about 120-150 ft. I play CQB anyways, so it's worth it. The great hop-up also adds to the range if you adjust it correctly. As most guns are, I recommend using .20 grams for best accuracy. The power of this gun is amazing and it feels good to shoot it. The Poor man's Chrono test that I did proved it.


One Side…………….290+FPS
Both Sides…………..340+FPS
Bottom Center………385+FPS*
Bottom Edge………...450+FPS
Top Center…………..470+FPS
Top Edge……………500+FPS


As you can see, the R74 shoots .20 Gram bb's about 290 Fps. Pretty Powerful for an mp5 that you can pick up at your local Dick's!


6. Accessories
Well, there is not much to say about accessories for this gun. The accessories it came with was the sling (The sling isn't the worst sling that I’ve ever seen, but it's still not that great), Allen Wrench for motor adjustment, .20 gram Crsoman bb's (they seemed alright to me, but I still didn't use them), battery, charger, and the 525-round magazine. I have reviewed all the accessories under the "Build/Quality" section. I also have tried to fit my Well R-8 rail on top of this gun, but it doesn't fit on it.


7. Modifications
For these, I figured that it was the same as the UTG mp5, so I used Captain Kev's recommendations for modifications.


-Stock Marui spring
-Replaced O-ring
-Re-shim job
-New hop-up bucking and rubber
-Silicone lube (if you want to call that a modification)


To my mp5 I have done all of these modifications to it. Good thing that I took some accuracy/ROF results before I modified it, otherwise this review would not be possible because it would not have been stock.



8. Conclusion
All in all this is a very well-built gun with a solid performance. if you are looking for an mp5 that’s around $100, eighter get this for range and accuracy, or the cm027 which is also a great mp5. This would be a great beginners AEG for anybody. With a few modifications, you can even maybe hold your own against those tough Marui contenders .
