[Set] R615-1 TTI Sand Viper (upgraded version) [JAG Arms] + Hi-Capa R501/R603/R604 Long Magazine - Black [JAG Arms]

Es la p**** sinceramente, el que diga que Taiwangun esto, Taiwangun lo otro que se coma una fu… va de locos el arma, la puse el kit crazyjet de maple leaf y solo tuve que rectificar una cosilla del cañon un poco con una lima (na que por 100€ menos que cuesta en cualquier otro lado no mereciera la pena hacer)

For an "upgraded version" i expected better quality, but i guess fancy CNC machined slide aside, Army Armament really haven't progressed much, quality wise.
1st issue - The slide stop it came with fails to lock back the slide. The funny thing is the same slide stop works fine in other hi-capas i own. Their slide stops also work fine in the Sand Viper, so who knows what went wrong there. But its annoying, because if i want a working lockback, i have to tolerate the color mismatch, and the primary reason i even got that pistol is the color.
2nd issue - that absolutely awful optics plate, and the way it mounts to the slide. Its cast pot metal, its uneven, it fits poorly to the slide, and it wobbles side to side. The screw holes came pre-stripped from the factory, since it screws directly into the blowback housing, which is made from the softest possible zinc alloy. There is a better solution out there, the R615D blowback housing and plate - but it sacrifices durability and performance.
No screws for the plate were provided in the box, and it uses m3 - 0.5 metric thread, so good luck finding them in any regular store - had to order in bulk from a specialized tool and instrument retailer - as opposed to regular imperial thread torx which you can buy from any gun shop that also sells real optics.
Seeing that the Combat Master Alpha and the incoming TTI x Ballerina Viper also use the very same plate system kinda soured me on the thought of buying them for my collection.
The funny part is, Army Armament makes a much better sturdier solution for the Staccato's they make for EMG/6mm Pro Shop, why don't just reuse that for your own high end releases?
3rd point, the trigger out of the box is the heaviest, stiffest thing i have ever experienced on an airsoft pistol. With a lot of dry fire and experimenting with the overtravel screw, it loosened up a bit, but it is still a far cry from my Jag Arms Pit Viper or Staccato. Replacing the leaf spring seems to be the only solution, but that also requires a lot of fidgeting and its beyond simple field disassembly.
4th point - The slide to frame fit is somehow much looser than my not-upgraded pot metal slide Pit Viper, which is a shame, because otherwise the CNC machined slide is absolutely beautiful.

What a unique replica. Jag Arms knows how to build a replica! The trigger is so good compared to other triggers. The colour looks very good in person and its build very tight and precise. If you're looking for a unique piece in you collection this might be the one!!!

Great Airsoft pistol ,well made.
I've not shoot with it, because I have to send it back because I feel to big in may hand :(
But maybe for some people who has bigger hand for sure will for for them.

Very, very premium high capa. Very good cycling through BB’, green and red gas no problem.
Went with the optics because it doesn’t have iron sights, and this thing shoots very straight. Nothing but praise to this replica.

Un excellent pistolet tant dans la finition que dans la fluidité mécanique

If you like to have a 2011 replica airsoft gun this one is the one to get! Nice and smooth Top gun to own I love it to shoot in the garden whit a red/green dot make this gun compleet

Very good quality and sturdy build feels like you’re holding a real piece, feels nice to shoot and accurate, the maintenance is easy and the mag is high quality, at the game people always come to me and ask about the gun.

The one thing that everybody needs one in Airsoft. After some time one is not enough. And after some time two is not enough!! This one in particular is great cause it can hold many BBs!! Fast package and well delivered!

This looks so slick in the Pit Viper. Working flawlessly so far. It has of course higher capacity which is always good and just has a great tactical feel to it. It's a must to make sure you don't run out of ammo in the battlefield.

⭐⭐⭐⭐⭐ Hi-Capa R501/R603/R604 Long Magazine – Black [JAG Arms]

This long double-stack magazine converts a Hi-Capa into a persistent field tool. Construction feels sturdy. The increased tank capacity allows two or more full strings of fire per fill depending on gas and BB weight. The feed lips and spring provide reliable indexing with no hesitation. With the magazine installed the pistol sits a bit heavier and that extra mass actually improves recoil control and target follow-up when shooting fast strings.

Field performance: in both speedsoft and IPSC drills the longer mag reduced reload frequency dramatically. In real games I often only needed to reload once or twice per engagement period. Gas efficiency is excellent when paired with quality green gas and the mag’s valve holds pressure even in cooler conditions. Loading BBs takes slightly longer because the loader window is smaller, but that’s a minor tradeoff for the sustained shooting time it gives you.

Practical tips: carry a dedicated extended mag pouch or a modified pistol-mag pouch because standard pouches can be tight. Keep the fill valve lightly lubricated with silicone oil and avoid overfilling. If you move between platforms, double-check compatibility with non-JAG Hi-Capa variants; most users report cross-brand fit but always test before a match. Overall verdict: the long mag is a high-impact upgrade for anyone who wants capacity, gas economy, and steadier handling without sacrificing feed reliability.

Hi-Capa R501/R603/R604 Long Magazine – Black [JAG Arms]
Summary: Reliable, gas-efficient long mag that adds both capacity and stability – perfect for competitive use.

Review:
I purchased this long magazine for my Hi-Capa and it has been a fantastic upgrade. The build quality feels solid, with a strong feed spring and no wobble once inserted into the pistol. Gas efficiency is excellent: a full fill easily powers two full loads of BBs without leaks, even in colder weather. What I especially appreciate is that the extended size not only increases capacity but also gives the pistol a steadier grip for competitive shooting.
For anyone considering it: make sure to use high-quality green gas and keep the valve lightly lubricated, as this keeps performance consistent. If you want both reliability and extra firepower in a single package, this magazine is worth every cent.

Pure workmanship. Very smooth operation. OOTB performance is fair. Might do well with the suggested barrel and hop-up upgrade.

Hop-up is a bit difficult to settle, as you need to remove the upper part from the body. It's not hard, it's just that other manufacturers have found ways to do this without dissassembling the product.

Best magazines for hi-capa pistols! This will allow you to run around not worrying about having enough ammo to last the round. Works in all Hi-capa brands, no problems or concerns between brands. I also like the way this matches my black 2011s!

Fantastic magazine, holds lots of rounds and gas
Its not even that uncomfortable and looks great on the pistol.
If u use the pistol as a primary this is the way to go.
Might be too big for some pouches

Increased magazine for Jag arms pistols. I got it for my combat master and my sand Viper and it fits like a glove. The magazine has an increased tank of green gas and BBs and is great for extending the shooting session. The only flaw is that the loading window of the BBs is small and it takes a little longer to load the BBs but nothing impossible. Recommended

I have never used a green gas canister and I can tell you that it is really simple to use. This 1000 ml bottle is fantastic value for money and, despite almost 1000 shots fired, there is still gas inside. In addition, inside there is a small amount of silicone oil that will lubricate your replica. Recommended

One of the most beautiful pistols available on the market. I can't stop looking at it! The grip is fantastic even if it stings a little but rubbing a little with the nails improves. A red dot is mandatory because it has no notches.

Amazing magazine which is not much heavier than the standard sized one, the capacity is good enough to where in games where I am primarily using my pistol I only have to reload this big mag maybe once or twice per hour but this also depends on how much ammo you are looking to use.

I was afraid it would be clunky to carry around or have in the pistol but it actually is not any different than the small ones, you just have to get an extended pistol magazine pouch.

I was never a Hicapa fan until I bought the Sand Viper based primarily on its looks. Holy moly this pistol is a beauty, the cnc finished slide is stunning with its polished highlights, its cycles so smoothly, the hand stippled grip feels great and not uncomfortable. It feels solid with a good weight and very little rattle.Another bonus is the steel fire group, hammer sear, disconnector etc, having these upgrades from the factory saves you time and money. Gun shoots with a sharp and snappy action, accuracy is on par with a TM Hicapa with upgrades. Overall a beautiful collectors piece at an incredibly affordable price, plus it can also hold its own on the battlefield 100% recommended, don’t forget to grab an RMR. Thanks Taiwangun, great service as usual

Excellente réplique pour le prix. Très performante en sortie de boîte. Les matériaux ont l'air solides, aucune fuite aux chargeurs. Bref, à posséder absolument !
Et avec une lampe couleur tan : un look d'enfer !

This gun has got me confused. It is a very beautiful gun, many people ask about it. The shooting is snappy, trigger pulls smoothly. The grip is really nice and is grippy, I would recommend to wear gloves when shooting though.

My gun did come with minor decorative defects (inner barrel was scratched), the outer coating also does scratch relatively easy, as only after one game putting the gun in my holster did leave scratch marks. The outer barrel is not fixed, so it has wiggle.

Also be very careful when buying a red dot, as the plate is RMR footprint, so make sure that the red dot you are buying is compatible.

It's the most good looking airsoft pistol that I ever saw. And it's good for bigger range too not for just indoor activities. The pistol grip is very good and 100% it will not slip out from your hand. And it's good that the magazine can't fall down accidentally because of the button is more out and.

Very nice , is looking very good , is handling very good , shooting also very good , very precise also and quick response at trigger , good material . Came in time , in good condition, nice packed , is a good replica , worth it all the money
