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

This is my second Army pistol, and once again it was an excellent choice.
Sturdy, nice shoot, good feeling in you and... Great option with great relation of value for money.
You will be very pleased with it... ;-)

Very good replica pistol. The feeling is very solid. Works smooth and great. A value for money product. The delivery was fast and in nice packaging. Everything was just as described.

5/5 rating for quality and delivery services.

Replicais a very good one for this budget. I very much love the softbes of its trigger. Slide is very well made, almost no play in it. As far as acuracy goes, it is good enough to compete with TM. Since i prefere to play CQB, i like to use it as much as possible and I am aleays pleased about its performance. I woul recomend as a secondary to anyone who likes 2011 models.

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.

Great gun. I still didnt use it very much But so far, great. Be careful because the trigger guard doesn't fit on some holster.
Is compatível with TM, and that is great. I tried several mags and ONLY TM is compatível.

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

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.

Good qualities, good presentation, brutal aesthetics, precision, the hop up rubber should be changed, the trigger is somewhat hard due to lack of lubrication, large BB and gas capacity in the magazines,

Bought this gun 2 weeks ago, nothing bad so far!
The R501 really feels solid and had some nice features out of the box. Like the nice grip and a magwell.
It gives a nice kick when shooting, even with my TM magazine. I say this because the AA mag releases more gas than the TM. The shots are nice consistent.
This is a good base to start from with many hi capa upgrades that fit.

About the delivery: nice and fast. Even got a free front grip for assault rifle!

Very good replica, ready out of the box. Pretty solid, beautiful design. Cheap, reable, durable.

It's a very good budget pistol. It performs well, it feels good in the hand, and most importantly it's cost efficient. For the price,you really can't go wrong with it.
The blowback feels surprisingly good with an impressive amount of recoil. I also love the sensation of pulling the slide release and feeling the heavy slide slide forward.
Flared magwell is a good addition. It feels exceedingly great to reload.
The magazine is also great. It can shoot around 100 bbs per gas refill which is very nice. My only gripe with it is the fact that the baseplate doesn't have a hole for refilling.

Daje pięć gwiazdek za jakość spasowania i kultury pracy do ceny.
Świetnie, że lufa zewnętrzna jest zescalona z kompensatorem na stałe i jest w systemie "non recoil" .
Dobra baza pod przyszły tuning.
W moim przypadku jak z forum Colt Hi Capa wlatuje Crazy Jet i głowica od Krackena.
Dodam , że replika przyszła niesprawna o czym poinformowałem sprzedawcę ,a on kazał mi jakieś filmiki wysyłać...... itp, itd, ale do rzeczy : po włożeniu magazynka I przeładowaniu reakcja na spust- brak strzału ,ale po przeładowaniu i włożeniu magazynka zaczął strzelać.
Winna była sprężynka resetu zbijaka, która była zbyt długa z czym sobie poradziłem,ale problem nie jest w replice, czy producencie.
Problem jest po stronie sprzedawcy,który opisuje , że : "Każda replika przed wysłaniem do klienta jest przestrzeliwana ,sprawdzana na chrono....itp ,itd.
Cóż nie mi pisać opinie, sami decydujcie

I was on the fence because every YouTube review was so positive i thought they were all paid adds. but the gun is just that good. all metal even the hopup unit. And the closest ive felt to a real guns trigger heavier than most airsoft guns but short crisp snappy been playing for 15 years best out of the box gun ive ever brought.

the highcappa is a great gun for the pricepoint. its very good when you need a fast switch to your sidearm in a cqb situation. the only downside are the mags which are a bit awkward to fill.

I have used this replica in a couple of games now and it has performed flawlessly. It resembles a compact version of a Colt 1911 with modded looks and features. The quality of the replica is top notch for the price with all metal construction and super smooth action.

A good sign of quality is that there's no play in the slide or anywhere else on the replica, so there's no extra rattling noises while handling it. Magwell is enlarged to ease the changing of mags. Safety switch is sort of a button, located in the back of the handle, that you have to depress while you grip the replica to enable the trigger to be pulled. In my opinion this is a great system in preventing misfires when handling the replica. The grips are also great, as they do feel like they really stick to your hand, making the handling easier and providing a firm grip even in a wet and cold weather.

I give this replica 5/5 stars, as my opinion is that you can't possibly get a better option for the price.

Perfeita, boa relação distância/precisão

good price

all around nice.

Magazines broke down because of poor polymer construction, full metal would be more durable.

Great Pistol for the price tag.

The slide fits the frame perfectly. The best sliding actions out of all of my hi-capas! The grip is very nice, although a bit rough, you will get used to it very quickly. Everything works pretty good. Would buy it again!

Several marks on the frame/slide, but apart from that nothing important.
