[Set] AT-AK04-PE with PERUN optical mosfet, ROF 25rps [Arcturus] + Airsoft DK-9 Style Russian Red Dot Sight for AK [JJ Airsoft]

Russian Style Red Dot at a good price. Easy to set up and very good workmanship. A must have for every AK player. Battery is included.
The Dot does not have strong phantom effects.
Really cool piece for the price!
Would recommend to anyone who wants to give their AK a real look.

This DK-9 style red dot really performs well in airsoft! It’s easy to mount, stays steady, and gives you a clear view of the target. The lens protector is a handy addition, and the battery lasts longer than you’d expect. If you’ve got an AK replica, it’s definitely worth trying out – a lot of people praise it, and for good reason.

It's sturdy enough, being built out of metal and quite heavy, but:
- dot intensity is quite low. During day time I have to set it to penultimate or even ultimate position;
- dot can't be adjusted too much. For example, horizontally I maxed it out to right, but it's still off by a few meters from target center;
- drains battery really fast. During winter time, a battery lasts 2-3 game days.

If you want high end AEG modern AK platform don't look anywhere but Arcturus lines of AK-s.

For me it's everything i wanted from AEG. Amazing performance out of the box, very good build quality and sturdy feel in hand.

This perticular version is PE which stands for "performance enhanced" and comes with perun optical mosfet. It's a bit on heavier side due to metal materials.

BATTERY SPACE :
Around 17mm x 17mm (on safer side). Maybe can fit 18mm x 17mm

I used 11.1V Gens ace 1400mAh battery 17mm*14mm*200mm. Others do not fit very well and this one provides aduqate power for this AEG. Good battery for high end AEG is a must.

I recommend other 5.45x39 mags which are higher quality then ones which gun comes with. I used 180rd AK-12 mags from WELL which fit without any wobbling. Check compatability for other mags.

Sling is recommended due to heavier weight.

Pros :
- Superb metal frame, solid build quality, dosen't wiggle in main frame.
- Rotary hop up (most aks have bad hop up)
- 13:1 Gear motor
- Optical perun mosfet
- 25RPS
- Piccotiny rail and MLOK mount on lower handguard.
- MOSFET : Rate of fire reduction, pre-cocking, binary trigger, Fire selector progaming, trigger sensitivity programing.

Cons :
- No battery space (holds very specific batteries)
- Lower quality mag which comes with rifle
- Mediocre stock (Small but NOT noticable wobbling in play).

Absolutely high quality replica. The body and the handguard are very solid. The magazine does not wobble. The upper receiver is a bit too tight, I hope it will get better with time. The shooting range looks good. It's fast firing.

I think it will be necessary to change the hop-up rubber, because after 35 meters it moves a little to the right and left. But it may just take time to break in. I really wanted a replica of this quality, and so far I have not been disappointed.

This is my best replica straight out of the box.
Really good quality.
If you want a AK modern style then this is your gun.
Don't need to change or upgrade anything.
shoot 60-70 meters straight out of the box.
And the Perun is fully programmable.
the only negative thing is the battery space there is enough, but it not a quick change. but wit a little bit of mechanical skills you can put it in the stock same as a M4
So in my opinion don't look further because this is a great gun

Sturdy build with a included killflash makes this a great addition no matter your loadout.
The dot is clear and helps aiming with no major adjustment needed right out of the box. It flips clock-wise between different brightnesses but can also flip to full brightness from "OFF" instantly if you flip it counter-clockwise. Helpful for those tight situations where you don't want to fidget with the settings.
Beware that it will not fit properly on uneven RIS such as the CYMA AK-mount (FBP0372) due to it being fastened with two screws. Make sure it is even 22mm.

+ looks great
+ Can use a rechargeable AA battery
+ Comes with a kill flash
+ Very sturdy build, with the metal construction

- bit on the heavy side

Note that was a little bit bigger than I expected
