[Set] R603 - Black [Army Armament] + Hi-Capa R501/R603/R604 Long Magazine - Silver [JAG Arms]

I am extremely satisfied with these extended magazines. Despite their size, they are surprisingly lightweight, which is a massive advantage during intense CQB matches where agility is key.
Visually, the silver finish is stunning and gives the Pit Viper a very aggressive "John Wick" look. A very practical detail I noticed is that, because they are extended, you can easily get a glimpse of the remaining BBs through the feeding track even while the magazine is inserted in the pistol. This allows for much better ammo management during a game.
Gas efficiency is great, and they feed perfectly even with rapid fire. Highly recommended if you want more firepower without weighing down your setup!

Of the three that I ordered, 2 of them work perfectly. One on the other was leaking at the fill valve and I tighten it and it worked for couple of games. Tried doing multiple things, lubing it, loosening it and retightening it. Unfortunately did not get it to seal like the other two. I'll eventually figure it out. However, love the look of it, Works well in any of my Hi-capas, so no differences between brands. Recommend this product despite me figuring out how to get it to seal on one of them.

The Army Armament R603 is a standout choice in its category, with premium build quality and performance right out of the box—no modifications needed. Compared to similar replicas, it’s perfect for players seeking reliability without the hassle of adjustments.

One heads-up: although CO2 magazines were available when I purchased it, I discovered the R603 doesn’t actually work with CO2 despite being able to buy ‘compatible’ mags for it. I even checked with support, but unfortunately, CO2 isn’t an option. So, I’d recommend sticking to gas mags for reliable use. Aside from that, the only minor quirk is a slightly loose right-side safety, while the left-side works perfectly. Overall, it’s a high-quality, dependable pistol that’s ready for action straight from the box.

This Replica is absolute value for money it is complete made of metal feels really sturdy, it shoots very good (by temps above 15 degrees Celsius but this is normal for green gas)
The build quality is above expectation, the only minor is Thera are no logo's or engravings.

A great value for money pistol. The build quality is absolutely excellent. Its a very lightweight pistol with an amazing grip that makes it stick to your hand and never leave you alone when on the battlefield. A trustworthy friend when it comes to combat

I will start off straight to the point.

Pistol is amazing, functionality, durability, size, and performance

When I go and compete at airsoft events this pistols gets the job done and is so fast, as the slide is light and doesn't use much gas for the slide to move fast which is good!

And as you should know this is a great replica of the staccato so if you shoot real steel and conceal carry this is perfect to train with and the best part is through this website it gives you a really good holster for cheap if you buy this pistol as a bundle

All in all perfect pistol to compete/play airsoft and train real steel.
