I previously reviewed the Tokyo Marui Compact Carry Gun No. 4 CURVE.
This model is customIt seems to be trending.I'd like to break it down in a bit more detail, hoping it will be helpful.

break down
We'll be disassembling the clip shown in the photo below. Incidentally, you don't need to remove this clip first, but I removed it because I thought it might get in the way during disassembly.
The clip is secured with two hex bolts, so we'll start by removing the bolts.
Next, we will break down the slides.
The slide is secured by hexagonal bolts visible from the front of the unit, as shown in the photo below, so we will remove them.
Slide the unit slightly forward before removing it.
This will remove the slide.
The slide has come off, so let's take a look inside.
Other side
The loading plate is not fixed in place but simply fitted in place, so remove it carefully.
Next, we'll remove the barrel.
There is a grub screw at the base of the barrel, so remove it.
The barrel can be removed by sliding it towards the rear of the main body.
Now the barrel can be removed.
Let's take a look at the barrel.
The barrel has a constricted shape in the middle, and it's a rather elaborate design, making it look like an expensive barrel.
The hop-up protrusion is the standard bump shape used by Tokyo Marui.
Let's try removing the hop-up packing from the inner barrel.
First, remove the hop-up arm. The hop-up arm is held in place by the elasticity of the arm, so remove it carefully while applying some force.
Remove the hop packing. It's fitted quite tightly, so warm it up a bit before carefully removing it.
Finally, remove the sleeve.
Now I've managed to disassemble all the hop-related parts.
Next, remove the outer barrel.
The outer barrel is secured by two screws, as shown in the picture below, so remove the screws.
Now you can disassemble the outer barrel.
• Screwdriver set
While cheaper options are fine, for affordable yet high-quality products, I recommend brands like Hazet, Tone, KTC, and Vessel.
Next, we'll remove the hammer and trigger unit from the main frame.
The hammer and trigger unit are secured to the frame unit with three screws, as shown in the picture below, so we will remove the screws.
Remove the hammer and trigger unit from the main frame.
Now the trigger unit has appeared.
Now we'll disassemble the trigger and hammer unit.
Now, let's remove the trigger bar. The trigger bar isn't secured with screws or anything, so you can just remove it.
Next, remove the trigger bar return spring. Be careful not to let it fly away.
We'll remove the trigger. It's secured by two screws on the back, so remove those screws.
This will release the trigger.
We will now disassemble the trigger and hammer unit chassis.
The unit is secured by the three screws shown in the picture below, so remove the screws.
Once you disassemble the unit, it will look like the following picture.
In this state, we will remove the trigger and hammer. The trigger and hammer are simply inserted into the shaft, so they can be easily removed.
Finally, remove the remaining safety and front cover from the frame.
The safety is simply resting on the frame, so we'll remove it.
Next, remove the front cover.
Remove the hex bolt.
Press the tabs that are attached to the inside of the frame, as shown in the picture below.
Press the tabs and push the cover forward to remove it.
This allows you to disassemble most of the parts.
Summary
Because of its fairly simple structure, it only took about 30 minutes to disassemble. The only tools needed are a screwdriver and an Allen wrench, making it quite easy.
The structure is quite simple and the number of parts is minimal, so I think it's an ideal product for those who are just starting to learn about maintenance and customization.
Normally, I would write articles by disassembling the product and commenting on any areas for improvement that would make me want to customize it, but this product has such a simple and complete structure that I could hardly find any.
One area for improvement I've noticed is that, since it's a fixed-slide gas gun, the trigger pull is a bit heavy. I'd like to make adjustments to improve its operability.
Next time, I plan to introduce assembly, adjustment, and a mechanism explanation.
Tokyo Marui Compact Carry Gun No. 4 CURVE Fixed Gas Gun
The actual market price is 6980 yen, so you can use it as is, or I think it's also perfect as a base for customization.
Tokyo Marui CURVE Spare Magazine
It's not a model that fires in rapid succession, but since it only holds 10 rounds, it would probably be more practical to have a spare.
