"I got this because I was having problems with my Tokyo Marui 5.1 Hi-Capa and was hoping that something in this kit would fix the problem. I will go over my experience with each part in detail:

Loading nozzle - 3/5
The nozzle seems standard and in no way special, simply a replacement part. When putting this part in my Tokyo Marui, the performance decreased, so I'll be sticking with the stock TM nozzle.

Piston head - 4/5
The piston head looks very nicely made. It has eight ports, made of aluminum, and has a nicely made o-ring. It provides a tight seal with my stock TM nozzle and an even tighter air seal with the nozzle that comes with the kit; normally, this is good, but it may be a bit too tight, so the nozzle may be able to get stuck, but I haven't encountered a problem so far. I am using this piston head over the stock TM piston head.

Cylinder bulb - 3/5
The bulb is good as well. It has an o-ring to help guide the gas so it doesn't escape, but I doubt that it helps that much. When installed, I noticed a bit of an FPS increase, but nothing to freak out about. I am using this bulb over the stock TM bulb, mostly because the stock bulb is plastic.

Recoil spring - 5/5
I am very happy with the recoil spring. It is stronger than a stock TM, a stock WE, and a Guarder 150% recoil spring, just as expected. I am using this in my TM and am very happy with it.

Hammer spring - 2/5
I was VERY VERY VERY disappointed with this spring. It is VERY nicely made, but was disappointed with its strength. It's stronger than a stock TM spring, but it is weaker than a stock WE and Guarder 150% hammer spring. Very disappointed with that. I won't be using this hammer spring in, well, anything. Ever.

Overall, this is a good kit.

"This is a nice kit. Both springs worked well. My full metal Hi Capa 5.1 stopped locking open on an empty magazines after the initial installation of the recoil spring, but after 100 rounds or so, started working again. One other note on the springs is that mine were blue, while they are pictured and described as red. I can't imagine who would get upset over spring color, but I did notice the discrepancy.

The nozzle/bulb work nicely, but given the price of this kit, it would have been nice to have had the spring and clip preinstalled, rather than having to cannibalize them from my stock unit. It took me a fair bit of time to get that done, and it seems the manufacturer could have taken care of that for pennies.

I haven't used the piston, but it looks to be nicely made.

All in all, my gun's performance was noticeably better after the installation of these parts, and I think well worth the money that I paid for the kit. It turned my "OK" HiCapa into a nice, crisp shooter. Like others have said, I gained a few FPS, got a nicer recoil, maybe a faster ROF, and now go through a little more gas.

"This is a great kit...
Parts are precise and seem of great quality
Springs are strong
Noticeable difference in blowback speed, power, range, feeding, etc.

Gas Consumption
OMG: Maybe 1.5 mags on a good day

"This is an absolutely fantastic upgrade kit!!! It does exactly what it's meant to do and totally blew me away. The power output of my pistol (WE 4.3 1911 Desert Warrior) has increased quite noticeably but sadly as has it's gas consumption with the added high flow valve installed. Also the main recoil spring for this cannot be used properly in a 4.3 1911 simply because it is far too long and prevents the slide catch from working due to half cycle (enough to chamber a new round but not enough to for the slide to go all the way back). Which that is an easy fix if you have something that can cut it down to proper length such as wire cutters (don't use cheap ones trust me!) or a dremel to cut the wire shorter like I did.


Increased power
Stronger parts
Faster trigger response
Greatly increased recoil thanks to those hefty 160% springs


So far none at all except for the spring modification I had to make in order to use it in my gun.

So 4 out of 5 stars because it was advertised to fit in both models and infact doesn't
