TECHNICAL: PERUN UPDATE
A NEW DAY... A NEW
KEEPING HIS EYE FIRMLY ON USABLE PERFORMANCE UPGRADES THAT CAN BE CARRIED OUT EASILY IN YOUR OWN WORKSHOP, THIS MONTH JIMMY TURNS HIS ATTENTION BACK TO PERUN AND TAKES A LOOK AT THEIR VERY LATEST DEVELOPMENTS AND WHAT THEY BRING!
I’d like to start by thanking Perun again for offering us the chance to test their latest products, as they’re great little company working hard to bring airsoft forward and aid us in our search for perfection. You may remember a few issues back, I had the immense pleasure of reviewing a few of their fantastic Mosfets which I was very impressed with, especially the etu++.
This time I got to have a look at their newly released products, the new hybrid system, both the v2 and v3 and boy, are these good! I would like to stress that we at Airsoft Action are all about open and honest opinions, no smoke and mirrors and Perun do not pay us in any way to test and review these products, we do it purely for the love of airsoft and seeing where our 6mm adventures may lead!
As stated in previous articles I’m smitten when it comes to new tech; I get a real buzz when I get something new on my desk and being tasked with fitting and testing truly is an honour. I started doing a little research in lieu of their arrival, so had a small understanding of what to expect and Perun have created something I truly believe will be a choice contender.
If you, as an airsofter, are searching for something that will transform your AEG, is easy to understand and operate, is of a respectable price and is going to give you an edge on the field, then look no further, as Perun has you covered. One thing I love about Perun is the fact they don’t overcomplicate things by adding features that some may see as unnecessary. They make things simple for the users and not only do they keep it simple, they also make it cheaper than most, meaning it isn’t just aimed at the customers with bags of money. It really does prove the point that, for something to be good it doesn’t require large sums of money. By keeping it simple, I mean the fact that you don’t need anything extra for it to work properly, Perun get two-thumbs-up from me!
The hybrid system has been designed to eliminate the need for a mechanical trigger system, making it much more reliable and also offer the user a whole array of features, allowing you to fully tailor your rifle to your needs - and enable the use of LiPo/Li-Ion batteries up to a whopping 14.8v which for airsoft is a huge voltage (and I’m yet to meet anyone who uses that voltage but if you feel the need rest assured the Perun can easily handle it). Information on battery capacities and “C” ratings can be found following the link supplied in the manual.
Operation of these new units is fairly idiot-proof (which is a massive bonus) and it can be done on the fly, so no need for USB leads, apps, Bluetooth, or firmware. Providing everything has been fitted correctly, the hybrids work out of the box and come with factory settings already setup on parameters such as AB and LiPo alarm and trigger sensitivity; being able to adjust the parameters only makes it work better.
When you look at Perun’s packaging it really is very simplistic; it doesn’t need to be fancy, it doesn’t need to be eye-catching because it’s what’s inside that
really matters. Inside you will find everything needed to install both devices. So much quality here I might add, there are no half measures, the soldering is perfect, nothing is out of line. As I mentioned with the other Mosfets I tested, the insulation on the wiring they have used feels a bit tougher than on previous versions.
I had a look through the instructions, which can be easily found via the QR code provided, just to check that there were no special requirements for installation. The v2 is really very straightforward and fitted in perfectly without any problems whatsoever, whilst the the v3 was a little more involved and required a small amount of soldering and wire management. Still, it wasn’t rocket science as the installation guide is very clear and precise.
FIRST FITTING
Fitting the v2 was very straightforward indeed, but when fitting something like this it is best advised to completely strip the gearbox. The unit fitted perfectly with no need to modify the shell; note this will fit in both a standard v2 gearbox and an ICS split gearbox. The hybrid device utilises both optical sensors and electromagnetic sensors: optical for the sector gear and fire select and the magnet for the trigger so you need to install a magnet onto the top of the trigger but, rest assured, no gluing is involved as they provide a very handy little brace which is screwed onto any existing trigger.
Next will be to ensure the sector gear aligns with the unit, which is clearly marked so you can’t really get that wrong and also to check clearance of the gear over the sensors; fail to do so could result in the gear damaging the device, rendering it useless. Provided also are selector plate stickers; choose the correct sticker for your model. With these parts prepared and installed it was time to check they were all working together by way of sensor checks. This is again a very straightforward process and using a series of light indications will point out any errors in your install.
Once fully fitted and put through a series of tests, the only thing I discovered to be a little bit of a flaw was the trigger over-travel - but not a major flaw I might add. With trigger sensitivity turned to max it did give me a very responsive trigger but I had a lot of over-travel. This is fixable and I shall do it at a later date, by way of an adjustable aftermarket trigger. Adjusting the trigger to remove a lot of the travel then turning the sensitivity to Setting 1 will sort this out.
Fitting the v3 (as I mentioned) was a little more involved. The device itself works exactly the same way as the v2 using optics and a magnet but, as you may well know, the fire select and the triggers are configured very differently. Please note: This device will not work with an AUG gearbox due to lack of selector plate. The unit fitted very easily with no need for any modding and is held in place by one screw; some v3 have two screws but one is sufficient. As with the v2, once the unit is in place it is crucial to ensure clearance of the sector gear over the optic sensor, as failure to do so could lead to irreparable damage. With the trigger, you have to replace the top half that houses the magnet which is supplied and is a very nice fit on the gearbox. The triggers on a v3 can sometimes be a little problematic to install, so I usually leave that until last just before closing the shell.
The selector plate is different on the v3 and does not use a sticker. Instead, there is a small plastic plate which gets glued into the selector. A small tip I found to be very helpful…. before removing the gearbox from the receiver, switch the fire mode to semi-auto and make a mark on both the gearbox and the selector plate at exactly the same point. When gluing in the sensor plate the gearbox will be out of the lower. With the two marks lined up it will be easy to establish where the selector will end up in semi and here you can precisely install the sensor plate over the optic sensor, ensuring perfect placement. An alternative is to refer to the diagrams in the manual, which offers precise measurements on certain specific gearboxes.
CHECK AND CHECK AGAIN!
Once all is fitted you then need to go through the easy sensor check, just to be certain everything is where it is supposed to be. Do carry out the sensor checks before fully reassembling the AEG. You will never be at a loss when it comes to settings on the hybrids, as Perun include a nice playing-card sized guide which can be fitted in your wallet, along with a couple of stickers which can be cleverly concealed somewhere on the AEG’s body, plus a sticker which gives you troubleshooting should any troubles arise out on the field.
Programmability is easily carried out: A couple of flicks of the fire selector sees you instantly in the mode and a series of trigger pulls will allow you to change the parameters. Each mode is indicated by a different colour on the LED and can be seen through various apertures on the gearbox. Each colour indicates a different setting and is the same over both the v2 and v3. Programme modes are as follows:
• Fire Mode: Adjust from single shot up to 5rd burst and also gives the option to turn a particular mode off which is great if being used in a DMR platform or a site only allows the use of semi auto. • AB Active Brake: The ability to stop the motor the instant you release the trigger. The device comes factory-et at Level 3 but you can turn it fully off or adjust as far as Level 5. The need for active break can occur on many an AEGs and can combat overspin. • Pre-cocking: With this setting you can set the piston to a specific state upon release of the trigger and you are given eight different positions: 0 being no pre-cock, 8 being fully pre-cocked, making follow up shots much quicker. I’ve found on past builds a small amount of pre-cock can actually be useful and rule out some feeding issues, although leaving a gearbox pre-cocked can decrease the power of your spring, which results in a loss of velocity though. • Binary Trigger: Somewhat a favourite of mine
I must admit! Turn your trigger from one shot per pull to two shots per pull! • Two Stage trigger: This mode will give you two different modes on the same fire select and can be altered to give different fire modes. If you pull the trigger slightly it will shoot in semi, then pull the trigger further to operate the burst mode. • Trigger Sensitivity: This allows you to adjust the amount of travel needed in order for your gun to fire. It is adjustable between 6mm down to 1mm of travel. A hair trigger can be achieved with an aftermarket adjustable trigger blade. • ROF Reduction: In some cases a reduction can be very useful. You may be overspinning due to a high ROF and rather than adding more active brake just drop the ROF a little. The hybrid offers five levels starting at 6% and giving a maximum of 30%. The level of reduction needed will be specific to the type of build you have. • DMR Mode: The DMR is a semi auto only rifle, and with a DMR some sites will require you to have a delay between shots. DMR Mode does exactly that, ranging from 0.25second up to 3 second delays. • LiPo/Li Ion alarm: This is a great addition as it will indicate that your battery has depleted to the point it could become compromised. More for the LiPo battery than the Li Ion, a LiPo that
drops below a certain voltage can be rendered either useless or volatile. At 3.7v the device will sound a warning telling you to no longer use the battery until fully charged again. It will automatically sense the amount of cells being used meaning no further programming is needed other than to turn it on. I recommend always keeping the alarm on. • DSG mode: There is no adjustment on this mode, it is either on or off and allows control of the sector gear giving the correct cycle time. • Master reset: The final mode, using this will set your device back to factory settings exactly how it came out of the box. Holding the trigger down for a few seconds will set this. This is useful if you have set a parameter and cannot find your way back to the original, when it’s easier and quicker to start from scratch.
If you can make a cup of tea then you can programme this device! Perun have made it very user friendly and I would highly recommend to anyone seeking performance upgrades that they should seriously think about installing a Perun Hybrid System or any other Perun product to meet their demands. As always, I would like to say a massive thank you to Perun and once again say keep up the good work!
