  • Programmable ETU inside
  • Takes ARP-9 magazines
  • Ultra-compact and lightweight

If you have been eying up an AR-9 recently, your choice just got more difficult! Introducing the PX9 from Classic Army, a compact and maneuverable AR-9 AEG with a built-in ETU which can be programmed for burst mode! The PX9 is equipped with a hybrid Picatinny M-LOK railed handguard, railed receiver and a highly flexible PDW stock which can still fit a standard buffer tube sized battery inside! 

Full description

Description

The Classic Army PX9 is constructed primarily from high density polymer, keeping the build light, scratch resistant and highly conducive to effective CQB performance. The PX9 is hot on the heels of the G&G ARP-9, borrowing its aesthetic and sharing the same magazines, allowing you to share mags with ARP-9 equipped teammates. If you are after a CQB primary for when your arms get tired, this would fit the bill perfectly, being a featherweight 1.7kg! 

Starting from the front, as we often do, we can find a polymer sound amplifying muzzle device, which gives the PX9 a stifling muzzle report. The "snap snap snap" of a triple tap from this AEG drowns out its motor noise, and is loud enough on the shooter's end! If you are downrange of the PX9 you will definitely know about it, and from the shooter's perspective, this will allow you to more effectively suppress the enemy team and gain the upper hand. Ths device attaches to the 14mm CCW male threads at the tip of the alloy 5 inch outer barrel, allowing you to change up the look of the PX9 if you are more of the sneaky type, and may not benefit from the intimidating muzzle report. 

Surrounding the outer barrel we are treated to a hybrid 20mm Picatinny M-LOK handguard which provides Picatinny rails in all the places you will need them, and substitutes M-LOK in at the 3 and 9 o'clock position to keep the front end of the PX9 light and easy to point. The Picatinny rails are present at the 6 and 12 o'clock positions to provide mounting points for a vertical front grip and PEQ laser unit, should you see fit to mount them. On either side of the handguard there is a small section of Picatinny rail, conveniently providing just enough space for a tactical flashlight to be mounted when the situation calls for it. 

The 12 o'clock handguard rail meets the receiver rail in a monolithic manner, providing an uninterrupted rail which is long enough for even the biggest rifle scopes out there. We don't expect anyone to mount a massive scope on the PX9, that's not really what it is for, but this longer attachment interface is perfect if you plan to use a red dot sight and magnifier combo. As it comes in the box, the PX9 has a pair of Troy style flip-up iron sights installed which provide a protected front sight blade and two rear apertures to choose from. The rear sight is adjustable for windage using the dial on the right side, and the front sight can be raised and lowered to adjust for elevation using an AR15 front sight adjustment tool. 

Moving to the receiver, we can see the familiar sight of M4/AR15 controls, which are ideally placed for fast access and manipulation. The magazine release can be found on the right side of the AEG, and sits well within reach of the shooters trigger finger, allowing for a highly fashionable "drop free" reload. The fire selector is found on the left side of the AEG, directly above the pistol grip, and sits comfortably beneath a right handed shooter's thumb when in a firing grip. Each fire mode is denoted with markings, reading "SAFE-SEMI-AUTO". This fire selector is a modernised design which is enlarged where it is useful and reprofiled in areas where non essential weight can be reduced. The selector has serrations on the upper and lower surface, ensuring that you can operate this important control effectively whenever you need to. The trigger of the PX9 is a flat "speed" style trigger, intended for rapid semi-automatic fire. The trigger has a helpful ledge at the bottom, assisting the shooter in staying on the trigger, regardless of how much it is getting spammed! The left side of the receiver also feature a dummy bolt release catch, which does nothing on an Airsoft AEG, but has nonetheless been styled up to match the design of the fire selector and magazine release, tying the whole gun together. 

At the top rear of the receiver, we can find the ambidextrous charging handle of the PX9, which is designed in a similar fashion to popular "raptor" style charging handles. The charging handle does not need to be pulled to prime the AEG, but instead retracts the mock bolt carrier to reveal the rotary adjustable HOP-up system. The HOP-up can be adjusted from the right side of the AEG whilst the charging handle is held to the rear. The rotary unit is widely known as superior to the legacy gear HOP unit and provides more stable adjustment with less likelihood of the HOP setting being affected by the vibrations from firing. 

The pistol grip of the PX9 is an ergonomic type with a filled out backstrap to make the AEG more comfortable to hold when not wearing gloves, or for those with smaller hands. The pistol grip has linear texturing on the front and back staps, and crackle texture on the sides to provide optimum grip in any weather conditions. One of the aspects which makes the PX9 so compact is its 2 position PDW type stock, found at the rear of the AEG, right where you expect it to be! This stock is one of the best PDW stock designs for Airsoft, as it provides the compact form factor to allow for easy transportation and storage whilst still providing enough space for standard M4/AR15 buffer tube stick batteries. We recommend a 7.4V 1300mAh LiPo battery for the PX9 to provide the best possible trigger response and prolong the life of the AEGs ETU. To access the battery compartment, simply extend the stock and pull the tab with the allen screw in downwards, which should allow the bottom part of the stock tube to come free. Inside you will find the mini-tamiya connector to which you connect your battery.

Now, onto the internals, and you are going to be as surprised as we are! The PX9 has its own programmable electronic trigger unit, which can be set up for either 3 or 5 round bursts, either replacing semi auto or full auto! This is very useful for Airsoft skirmishes with limited magazine capacity, as it will help you avoid the temptation to spray the enemy down, whilst saving that ability for when it is absolutely necessary. For information on how to program the ETU, see the "Special Instructions" section below. The ETU also provides motor and battery protection, and will prevent the PX9 from being fired when the battery is low and potentially damaging the cells.

The most notable part within the PX9 is its 6.03mm tightbore inner barrel, which provides excellent accuracy in such a short package, in concert with the rotary adjustable HOP-up unit. It is rare to find such a feature packed AEG at this price range that isn't a bog-standard M4, seeing this in an AR-9 is refreshing, to say the least! Also present inside the PX9 are 9mm bearing bushings, keeping the gearbox running smoothly, and a quick change spring system, which can be useful for those who want to personally tune their PX9 to their local site's FPS limt. There is little need to do so, as when tested the PX9 shoots right around 340 FPS +/- 10%, putting it in that sweet spot where you can be sure environmental factors cannot cause your AEG to creep up and shoot above limits whilst being right up there at the edge of what is allowed at most skirmish sites!

Classic Army ETU Programming Instructions

Inside your Classic Army PX9 you will find an instruction manual with all the details on how to set up you ETU in various configurations. In case you lose the instructions, or you are just having a nosy, here is how to program your CA ETU:

Please ensure your AEG is clear of all BBs, the magazine is removed, and eye protection is worn throughout this process.

Step 1: Set your fire selector to "SEMI"

Step 2: Depress the trigger for 5 seconds until you hear the ETU beeping

Step 3: Release the Trigger (the ETU will continue to beep - the beeps denote the current settings)

Step 4: Depress the trigger and hold it for 3 seconds

Step 5: Release the trigger once the beeping sequence changes. If you want a different setting to the one indicated by the beep sequence, repeat step 4 and 5 until you have the required settings. 

Step 6: Once you have your desired setting, turn the selector to the AUTO position to store the setting. 

Settings

The following is a list of the settings available for the CA ETU and the beep sequence denoting each.

  • Default   - SAFE-SEMI-AUTO - Beep, Pause, Beep x8
  • Setting 1 - SAFE-SEMI-3 ROUND BURST - Beep, Pause, Beep x3
  • Setting 2 - SAFE-3 ROUND BURST-AUTO - Beep x3, Pause, Beep x8
  • Setting 3 - SAFE-5 ROUND BURST-AUTO - Beep x5, Pause, Beep x8
  • Setting 4 - SAFE-SEMI-SEMI - Beep, Pause, Beep

Size guide

Joule Charts

Special Instructions

These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.

FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.

Tap the tabs below to open the relevant chart for your replica.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
