It does what it's made for. I mean it just works, there's nothing more to say about it. It charges the battery fast, has the lights to indicate how much there's left. Vingardium leviosa. I really don't know what to say....

For the price, it's really worth it. It works better then my friends. You can actually see wich cell is charged, and with the help of this, you can see wich cell is damaged. Because of this new charger (because I used to charge my battery with my friends charger), I realised that my old Li-Po battery is gone bad, so I had to buy a new one. If I wouldn't have bought this battery charger, I wouldn't know what went wrong: my battery or my gun

Unless you want one of those big fancy ones with a screen telling you everything that's going on (which you realistically don't need for airsoft) this is the best pick.

Fast reliable and very affordable charger, takes about an hour to fully charge a 11.1V 1300mah lipo. Also very fast delivery and packaged safely. Im writing the rest of this text cause it needs to be 200 characters long :)

Great charger! The 3 leds give a nice red and green indicator on which cell is loaded. That way you know when to take the battery off the charger. For the rest it charges and haven't had a single problem with it.

Odpowiedź sklepu:I don’t know if its only with me, but from the very first use of the charger it did not perform well. I put my 11.V li-po battery in it and it said that it has no charge so I left it as it is. After more than an hour not even one cell was charged. Then I reconnected the battery with the charger and it showed that it was fully charged. Then yesterdays after my first game a put another battery, brand new, to charge it. Left it overnight (i know its not good) and today i tetsed if it was fully charged- i was not. The green dots are always going from green to red despite the fact the battery has been sitting long enough to the chargerWe are sorry that such a situation occurred.

A timeless classic. When you choose to buy an MK12 SPR Mod 0, you already know what you're looking for and what you want chances are you've seen it in some American movie or video. In short, you're a true connoisseur or nostalgic. But in 2020, where could I turn to get one? I just couldn't find it anywhere, much to my disappointment. Then, Double Bell came to the rescue. With great expertise and modesty, they have masterfully crafted this MK12, offering it to us at an incredible price through our beloved Taiwangun!
It arrives at your doorstep in the usual very well-built protective packaging from the trusty guys at Taiwangun. A much-needed package for this replica, as it comes in a rather basic box with no additional protection—just plain cardboard with a few cutouts to keep it somewhat stable, no battery or charger (but we really need an Ni-mh nowdays?)
What you'll find inside is an MK12 that, yes, might remind you of the beloved models that were popular around 2007, but this time with a fresh, juicy, and updated twist. Right away, you’ll notice that nothing wobbles on this replica, thanks to the sturdy handguard that extends along the upper receiver's rail the truly unique feature of the Mod 0.
The colors are pleasantly matte and truly stunning we can't see imperfections. The materials is consistent metal everywhere except for the stock and grip of course. The stock has a matte, rubberized-like finish, but don’t worry it’s not the usual soft-touch coating that turns into sticky glue over time, this is an upgraded finish that looks great and hides any casting lines nicely, making you forget all about the old stocks from back in the day.
Pulling the charging handle, you’re immediately greeted by a chromed mock bolt that locks back in place, ready to be released with a simple tap on the bolt catch, which responds instantly and without hesitation. And here’s another excellent upgrade a smooth rotary plastic hop-up!
Speaking of mechanical upgrades, i can only mention the quick-change spring gearbox, taste of recent days at the same price as the gold old-times, we now get a package full of little upgrades that clearly show the manufacturer’s commitment to satisfying the buyer and give him a real thing. And I have to say they absolutely nailed it with me!
The rest of the moving parts, such as the iron sights and adjustments, are smooth and precise, just like the selector switch, which has a soft yet decisive click. I’ve seen better, but I certainly can’t complain about how well it engages.
I started firing a few test shots, and soon my expectations were exceeded. Let’s not forget that this replica features 8mm bushings, and when I peeked through the magazine well, since I haven’t disassembled it completely yet i saw a gearbox that looks pretty smooth in surface, perfectly paired with the hop-up. A good sign i will wait to open it to find something maybe.
The compact magazine works flawlessly, feeding every shot without any skip even if you move it, right it wobbles but is perfectly normal for this kind of ol'guys that eject the mags without friction when we push the mag release button. The gearbox have smooth cycling, especially for a stock setup at this price point.
What can i say more guys? Is a pretty simple but effective and sturdy piece here. If you’re looking for one and you want it, go for it for my opinion, give it more than just a chance. If you enjoy the marksman role, then its one downside, the weight, won’t be an issue for you because honestly, thanks to the round profile of the handguard, it’s incredibly comfortable to hold and you can plan to install a vertical grip in back area of the front, the rails are free modular here. Just slap on a classic Harris-style bipod, a long-range scope, a mock rangefinder or side-mounted PEQ, and a suppressor, and you’ve got a stunning setup for enthusiasts of the genre.
And of course, you can always go wild with an offset red dot, we all know that on this type of replica, they’re the cherry on top!
Thanks, Taiwangun! Always on point, bringing us these timeless classics at reasonable prices!! -

Very compact and light B3Pro charger. It is used for LiPo/Li-Ion batteries. Item work out of the box, yust plug it in a wall outlet and plug in your replica battery. I have used it many times and it works very good.

Il fucile è robusto e la linea è bellissima! Un pochino peso ma molto buono, io l'ho preso per convertirlo al sistema Xtag laser! E mi serviva un buon fucile stabile ma che non costasse troppo! L'ho provato con qualche pallino giusto per vedere e fa il suo lavoro! Il negozio Taiwangun è serio e affidabile ormai mi ci rifornisco da anni!

It’s a great charger, can charge 7.4-11.1 Li-Pos without any problems. Great price, simple and trustworthy. My friend got one too, since he had an Ipower B3 charger, which has electroshock problems…
In conclusion, great-great-great, get it! :)
Have a nice day! -

One of the best airsoft gun that I’ve ever seen for such a low price, I can definitely recommend the MK12 by Double Bell to anyone who wants to build a DMR, it comes with a rebranded Maxx piston/piston head, cylinder head and air nozzle, the hop up is a rotary unit and with a good stock hop up rubber and nub. I have 2 in my possession and they are the best DMR bases that I’ve owned.
Pros:
Maxx rebranded compression parts (super airtight)
Good rotary hop-up unit, rubber and nub, can hop 0.4 at 2.5 Joules
Cheap and affordable DMR base
Full metal construction
Includes a high capa and a midcap in the package
Quick spring change
Fake working Bolt catch
Fires 1.8 - 1.9 Joules at stock power
Shoots farther than a lot of stock aegs
Good shimming for a stock gun, doesn’t need reshimming
Cheap to upgrade, only recommends a mosfet, stronger motor and spring and a tight bore steel inner barrel to make it the perfect DMR.
Cons:
The gearbox is a little bit out of spec, be aware of that if you switch out to a full cylinder to fix a small hole for the sector gear to pass by without getting nudged into the cylinder.

Odpowiedź sklepu:The exterior build of the replica is solid, with an upgraded nozzle and piston head, and the shimming is decent. The Quickchange spring system is a nice touch. However, I may have received a defective unit, as the gearbox was significantly out of spec. The sector gear was making contact with the cylinder during rotation, likely due to either a production error or poor quality control from Double Bell. Unfortunately, this issue rendered the replica unusable. If you're considering buying this model, I strongly recommend opting for a TWG tune-up service to avoid similar problemsWe are glad that the replica you purchased was to your liking. If there are any technical problems, we invite you to contact our service - we will help to remove any malfunctions.

For the price it's a good replica.
- Weighty, basically full metal body with the exceptions of course being the stock and grip.
- Mags do wobble and might require a little more force for it to sit.
- Would recommend a bipod.
- Also would recommend a sling too
- Has good range -

In terms of price/value ratio, I think it's worth it if you don't want to spend a lot on a battery charger that can charge both 7.4v and 11.1v batteries. It charges my 1200mAh battery in about 2 hours at 11.1v charge.

A very good charger for Lipo/ Li-ion batteries.
The price is also good like always with taiwangun. I think that taiwangun is the best shop for airsoft in europe. The pric's for batteries are also good. I buy 2 Lipo 's and they work fine. -

The B3PRO compact lipo charger is an excellent choice for airsoft enthusiasts as well. This charger can be ideal for safely and efficiently charging lithium polymer (LiPo) batteries used in airsoft guns.
Its small size and lightweight design make it easy to carry to airsoft matches or adventures, allowing you to charge batteries anytime and anywhere to ensure they're always ready for action.
The B3PRO charger features several safety functions, such as overheat protection and short-circuit protection, ensuring that the charging process is safe and proper.
However, it's essential to always follow the manufacturer's recommended charging and usage guidelines to prevent battery damage and ensure their longer lifespan. With the B3PRO, you can easily maintain the performance of your airsoft guns, ensuring they're always ready for the next battle. -

Does the job well. A fantastic option for your Tamiya batteries, one of these chargers is a must-have for keeping your models powered up.
Offers safety and peace-of-mind when charging batteries, it can be quite stressful and dangerous to charge directly, in my opinion this is the best option for the price! -

Én egy 11,1 V-os akumlátor töltök ami Lipo nagyon gyorsan feltölti és szépen működik is vele minden. Nagyon jó a kijelző rajta hogy látom hogy mennyire van feltöltve az akkumulátor. Ár érték arányban nagyon megérte megvenni nem csalódtam benne. Gyorsan ideért megvagyok elégedve vele.

For the price it was definitely more than value for money, it looks amazing especially with a few attachments on like a scope and bipod. It shoots straight with no jamming on its debut.
One con is the grip is contoured for right hand so my dad found it uncomfortable after a while cos he's a lefty, guess he'll need to get his own gun . -

For the price , this gun is absolutely wonderful . Coming with a tight-bore barrel out of the box this gun shoots super far. The gearbox cycles wonderfully and without any problems . The rotary hop helps to lock in where you want your bbs to go . Now that we’ve talked about internals let’s mention the externals . For a small price , you would think you are getting a polymer body on this replica but no. The full metal externals give this thing a heft of weight that make it feel essentially like a super expensive replica .

A good battery for the price. Good construction and good output. I bought it specificly for the ICS M3 Grease gun. If you split the body of the replica, you can squize the battery inside it (behind the gearbox). However, you'll need to charge it with a simple charger that charges only via the small cabel on the battery.

Cheap charger, works well.
Don't expect features such as load balancing or discharging to a better charge for safer storage. Those are more expensive.
But it does the job well.
Definitely buy a LiPo charger so you can see the percentage of your battery before/during/after play. -

A great classic DMR platform. Very solid construction with no wobbles nor creaks. Only shoots semi as a DMR should. Highly compatible with AR parts and accessories. Shoots very well out the box. Be warned that It is quite heavy

A bit on the heavy side but that is surly not for the bad aspect!
The wepon is really sturdy and works really well! Especially with the tune up service that is provided here by TG, the weapon itself uses very accurate m5 bolt locks for the rail system that allows you to attach whatever you want to it! I used it to attach a bipod directly to the bottom of the rail and used the picatiny rail included to run a fore grip!
Do recommend it and fun thing to run around with! A good eye catcher if anything else!
