[Set] R609 - Silver [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.

Replica feels pretty good in hands, has a nice kick on blowback and is combat good. I would expect it to be a little bit more like the real STI 2011 Executive as far as logos and serial numbers is concerned, but it can be solved with engraving, so this is not such a big deal but is to be mentioned. Overall, good purchase.

My only complaint about this gun in the paint finish on the outer barrel is easily marked up and gets worn off by the slide very easily. Not a huge deal but worth mentioning. Besides that it's a solid performer and looks great. I ended up painting the grip black and adding a suppressor. Also using the extended bottom mags from the R604 in this and they look amazing

Solid pistol, like all of the other AA recent releases. My complaint comes from the silver painted outer barrel that quickly gets chipped and looks awful after a couple mags worth of shooting. It should have been a different finish that would hold up to the slide moving against it
