[Set] R604 - Black [Army Armament] + HPA Adapter Hi-capa Pistol Series for M4/AR15 Magazines [Army Armament]

Worked well just after purchase, I did shoot about 10 full magazines through it, and no iissue. It did lay un-used for a long time and now that I got it out once again to test it, outer barrel just snapped of at the back portion and fell to the ground! No previous damage to it. And now it is just useless junk or spare parts, I just can not find new outer barrel for it anywhere...

Great Performing pistol out of the box. No gas leakage and it feels nice in the hand. Please note it wont fit some hi-capa holsters due to its pistol sight at the front being a bit higher, so choose an adjustable one.

The gun itself is great, but the screws on top of the gun cant be unscrewed because of the pot metal, which makes the screws strip apart when trying to remove them. This is very bad since one of the main features of this gun is to mount a red dot on it's inclusive RMR-plate. Unfortunately the screws on my gun are now stripped and there is no way to remove them.

Pistol is good if magazine is working and not
Leaking or breaking all the time, an over value cheap set to buy, also the red dot cannot mount on pistol 2 screws are missing from the box.
Parts and magazines are always unavailable.

Super replique cela fait maintenant plus d’un an que j’utilise cette replique pour un peu tout type de terrain et de jeux , cqb et forêt, la replique est genial d’origine , cependant au cours du temps j’ai voulu de meilleurs performances et vous devez savoir que tous les upgrades hicapa fits completement sauf la detente AIP , compatible avec beaucoup de chargeurs , perso le miens est vraiment une pepite , un petit coup de frein filet pour le compensateur ca marche tres bien . Mon UNIQUE probleme dessus apres 1 an et demi c’est le chien qui a explosé mais bon aussi c’est pas une piece qui coute chere , si j’ai un conseil : usez le un max de temps puis quand ça commence a aller mal changez les pieces avec du 6,01 pdi , airsoft masterpiece , mapple leaf , cowcow, guarder, tout marche dessus et on sort du 350fps green gas , j’espere avoir aidé

Very good pistol. The slide moves so smoothly. I have many hi-capa pistols but this is the only one that it's slide is so smooth. Everything works out of the box as should and performance is great, but I've had two issues with my pistol. First one is that the ambidextrous thumb safety has developed a slight movement on the right side and is not as snappy as the left side. Second issue is how the compensator is attached to the pistol. The compensator is attached to the pistol by a o-ring that is on the outer barrel, which I don't understand why... Why the compensator is not attached with a screw to the body of the pistol? The o-oring on my pistol has broken once and I had to replace it, so if you buy this pistol take into consideration that in near future you will need to replace that o-oring. I suggest to put a electric tape around the o-ring to prevent it breaking. Other than these issues the pistol works great and is beautiful.

It looks really sweet.
Feels great.
Shoots straight and the sights are clear and fast.
Solid build quality.
Magazine slides in easy and the tabs gives you a fast way to switch them.
I use 0,28g bb's and they works great.
Triggerpull is a bit hard but not close to problematic and I can still shoot fast.

Overall a really nice gun for that price!

If you want a hi - capa based off certain real 2011 builds that shall remain nameless for the fraction of the price than look no further.
1. TM Compatible with the exception of modification to the blowback housing and slide fitment (though if you wish to slide I recommend the R603) as the outerbarrel of this hi capa is connected to the muzzle break.
2. Superb externals and great over construction
3. Good range and fps is decent
4. TM compatible magazines
5. And if you are worried about adding a tracer, look for the Army Armament thread piece for this gun here on taiwangun.

You really can't beat the price of the gun for the overall superb performing sidearm.

Compared to KJW hi-capas like the Novritsch SSP-1, the r604 feel much lighter and cheaper made. The magazine it comes with beats the SSP-1 magazine as it shoots way more shots. I hope TaiwanGun Release more new guns from Army Armament in the future.

One of the best priced pistols on the market currently.
Every single detail of the pistol has been perfectly manufactured. The pistol feels very comfortable even in bigger sized hands and provides a very stable and accurate grip when aiming with it.
The kick of the pistol rivals that of some CO2 models.
The trigger has a very short stroke making follow-up shots very fast and easy.
One of the best full-metal out of the box pistols money can buy.

I was a bit spectical when ordering this gun, mostly about its look, but I wanted to find out what it actually looks like in front of my eyes. It is a really nice gun aesthetically. I've heared that you need to a bit work to fit your RMR (i dont know about it cuz I havent put any RMR on it). Some people complain about its magazines leak, I had a lot of AA magazines only one was leaking and it was becouse of an O-ring on the valve I made my self different 0-ring from rubber and it works perfectly now. This replica has a really nice kick back!

I am in love with this replica, currently my favorite sidearm aesthetically. My only complaint is that right before I went on a trip the stock magazine started to excessively leak, I believe the fill port O-ring was a bit weak. Also the bottom plate of the O-ring doesn't have a fast access fill port for gas, which is annoying as I currently only have one magazine. I also am not sure what screw size the RMR plate requires, as the red dot w/ screws I have for it doesn't fit. However for this price my only complaints come down to an easily replaced O-ring and having to find what screws will fit so really all is well. I'd give a 4.5 out of 5 if I could but I believe a 4 will bring an appropriate amount of eyes to this review.

Needed a little chisel for red dot mount, but overall: great gun!

Good grip, comes heavy lubed, wich is good.

As I said: needed a little chisel for red dot mount.

The pistol looks great and feels solid.

Compared to previous models from AA, there are barely any marks on the exterior. Good lubrication inside and the slides fits very well. Also having the suppressor sights and the rmr compatibility at this price range is a very good thing!!

The thumb safety doesn't work well at all. The frame where the safety seats is not fully flat therefore you need to pull a bit the left safety out of the frame in order for it to be moved (up or down in order to engage the trigger), however doing so, you disconnect the right safety as there will be to much space between the 2 safeties (right and left) and they will not engage in the connecting point. Also, the trigger is very spongy and has a lot more travel than other models like the R601 or the R501. The rmr plate was a bit larger than the actual opening on the slide, I had to force it a bit in and it left some marks on the slide because of this.
