[Set] 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.
