Description
This style of rifle is quickly becoming an absolute staple, but what the SR4 ST Falcon-ZS has over most other offerings is the ability to switch between using 9mm and STANAG magazines depending on your mood using a simple adaptor. Built for intense and fast-paced CQB skirmishes, the Falcon is as light as a feather thanks to its full polymer construction, keeping you light on your feet, stealthy thanks to its integrated suppressor and in control with the included magwell grip plates.
Beginning with the front of the rifle, surrounding the 7-inch inner barrel, we have the integrated suppressor sporting SRCs suave looking engravings. Dampening your shots with its interior padding, this suppressor gives you that extra edge when flanking your opponents in CQB. The handguard features a honeycomb-like design, giving the rifle a sleek and modern look that complements the suppressor and sights and also sports two MLOK negative spaces, allowing for the attachment. of tactical devices such as torches and lasers, as well as the two included RIS rail attachments. Below the handguard, the Falcon features a QD sling point, to which you can attach a sling of your choosing and even use it in tandem with one of the two rear QD sling points if you prefer using a two-point sling.
Above the handguard is the top 20mm RIS rail that runs along the extent of the handguard and upper receiver, to which are attached the included flip-up and light enhancing aperture sights for superior vision when aiming. The rear sight boasts a rotary drum adjustment to allow you to adjust on the fly and always hit your mark. These sights can always be removed at your choosing if you want to opt for alternate sights or tactical attachments.
Moving on to the receiver the first thing we can see is the stylish SRC branded logo in keeping with the sleek look, but the real improvement over the standard M4 package is the inclusion of the magwell grip attachment, giving you that extra bit of ergonomic grip and security when running and gunning. Of course one of the main draws to this rifle is the STANAG to 9mm magwell converter. This attachment lets you use 9mm SMG-style magazines which is a hugely popular configuration right now, in part due to giving you the extra option of using your mag as a foregrip. The converter has a STANAG head which clips into the magwell and is removed much like an M4 Mag - by pushing the mag release button. This means that if your 9mm magazines are empty you can immediately decouple the adaptor and switch to your STANAG magazines keeping you in the fight longer. It may even throw off your opponents if they think you've run out of ammo when your 9mm mags run dry when you know this is not the case!
Above the magwell is the mock bolt release and while it does not serve any function in this Airsoft replica, it completes the look of the Falcon. The pistol grip is an improvement over the average rifle and SMG grips in that it has a textured, finger ridged design, giving you comfort and control that will never leave your hands in the heat of battle and is useable with or without gloves. Noticeably the grip also sports a thumb indentation, letting your thumb sit more comfortably against the grip when held.
The Falcon features an ambidextrous charging handle, which is fully functional for that satisfying snap when pulled during gameplay and also reveals the HOP adjuster. To access the rotary HOP-up adjuster of the Falcon you will need to pull the charging handle to the rear which will open the dust cover and retract the mock bolt, presenting the HOP-up adjuster on the right side. The charging handle is located at the top rear of the receiver, and is an ambidextrous design, allowing left or right-handed users to access the HOP-up instinctively, with no funny body mechanics involved. The rotary HOP-up unit is the current best design out there for the M4 platform, and is a worthy include in the Falcon.
At the very rear of the rifle is the PDW style stock. This design is the go-to, player's choice of stock for CQB gameplay as it is as compact as they come, giving you that extra bit of manoeuvrability during skirmishing. Adjustable with 3 positions, the PDW stock also completes the spec ops look of the Falcon, especially in combination with the integrated suppressor for a serious, modern operator vibe. The back end of the stock is bulky with a diamond texture that you will find immovable against your person, giving you a superior level of stability and accuracy during firefights. Either side of the stock unit are 2 QD sling points for carrying options.
The stock is easily adjusted with a push of the underside button. Extending the stock reveals the battery compartment, accessed by squeezing the two points either side and removing the cover. Because this rifle has been designed to be as economic with space as possible for tight situations the compartment is as small as can be. As such we would recommend a LiPo stick battery with Tamiya connection no more than 9.5cm in length such as the Specna Arms 7.4V 600mAh 20/40C Battery for PDW.
Internally the Falcon contains a wealth of modern Airsoft components to keep up with today's increasingly intense competition. It features a 6.05mm tightbore barrel and reinforced gearbox with a quick-change spring system. The steel 8mm bearings provide reduced friction when firing for smooth, buttery smooth action. The Falcon also showcases high-speed 22:1 CNC gears, along with an aluminium cylinder head with a double O-ring for better air seal, as well as a high torque motor.
The ability to pick and choose between 9mm and STANAG mags any time during battle is a huge advantage of this rifle and all this functionality comes right out of the box! The SR4 ST Falcon-ZS is expertly crafted to give you next-level performance in CQB skirmishes thanks to its incredibly compact design and lightweight build. So for all you operator and convert ops types out there, the Falcon has a superior look and functionality that sets it apart from the competition!

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.
This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
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.
