Well I've been talking about it for a while, so here it finally is!
Galaxy MP5K PDW ordered from
www.nitroairsoft.com. They are highly recommended! Great customer service!
Price $125 Shipped
First impressions:
The box that it came in is surprisingly good! I don't know who Galaxy is, but their translation skills are excellent!
Included:
In this fantastic, glossy box came the gun, 8.4v 1400mah NiMh stick battery, charger, sling, magazine style speed loader, 2 magazines, one high cap-full length, and one low cap-shorty, cheapo bbs. The usual stuff.
Gun first impressions:
Very high quality plastics. Metal is a bit iffy looking, but strength does not seem to be a problem. The gun itself is suprisingly heavy for it's size. No creaks, wobbles, shimmies, anything. Very solidly built. Metal parts include: Stock hinge, 3 lug 14mm negative threaded barrel, Body pins, Selector switch, Front sight, Lower mag release, Both magazines, and Cocking handle. The rest of the gun is made of nicely textured, very strong plastic.
Trades:
Holy crap! Kal.9mmx19 on the left side of the mag well! Nicely molded into the body. Other than that, it has the Galaxy logo below the caliber markings. On the other side it says made in china, galaxy, G.5. The fire mode indicators are painted on, but they seem sturdy, won't scratch off easily.
Firing the gun:
To put the battery in, you need to first remove the two rear body pins. You do this by pushing the retaining loops into the pin, and pushing them through the other side. After you take the pins out, remove the rear stock. Then you need to take the front pin/sling mount using the same method. Slide the foregrip off after that step. Slide the battery from the back to the front, snaking the wires past the cocking handle and into the area that the foregrip covers. Connect the battery to the gun. After you do that, you can carefully slide the foregrip back on, avoiding the battery wires. Do the same thing with the stock. Replace all body pins, using the same technique as taking them out. After loading the low cap magazine with 28 rounds, or loading the hi cap one with approx. 230, click it into the magazine well. Don't be scared to force it in the first few times. It has a strong spring that needs to wear down with time. Goggles on, weapon on safe, it's off to the range!
Performance:
The selector switch moves smoothly between it's settings, with a satisfying click at each stop. Click it from safe to semi and let out a few shots. You will be surprised with how loud and poppy this gun is! Trigger response is good, not great, but a better battery wouldn't hurt in this department. Shots are a little wild at first. Cleaning the barrel well will help with this. The hop-up adjuster is located in the area accessible by removing the foregrip. It's a little white tab that moves back and forth. Seems like it won't move on it's own, but only time will tell. On full auto, the ROF leaves a little to be desired. It's not particularly bad, especially when you consider that an 8.4v stick battery is pulling an M100 spring.
The gun chronod at 324-328fps with .20 gram matrix bbs consistently. Range, after tweaking the hop-up was 120' torso hit 9 out of 10 times. Past that, they go a little wild, but you're only working with a barrel that's about 4" long. Personally, I was impressed.
Modifications:
What's nice about this gun is that you can switch from a PDW stock, to a stockless K model by taking out 2 screws! Other than that, I have a sight mount from a Well R8, BSA RDS, Mock supressor from a $30 Lpeg. On the way is a 10" Element Mock mock silencer, and a 300mm Madbull Tightbore. Maybe an Intellect or a custom 9.6v wired into the stock down the line, but for now, the ROF is my ammo conserver!
Pros:
FPS
Cost
Build quality
Caliber trades
Size
2 Mags
Cons:
Metal could be better
ROF
Battery is a P.I.T.A. to get out! You pretty much have to charge it in the gun.
Overall:
I love this thing. It has replaced my AGM M14 as my favorite right now. With this much power in such a small package, people will think twice about making fun of your tiny gun! I give it a 9 out of 10
Let me know what else you want to know, and I'll include it!
Now for the pics!
With mount and RDS added:
Mock mock silencer, no RDS:
