If you like the economical and performance benefits of an AEG but cannot resist the urge for recoil, the PTS Syndicate Radian® Model 1™ M4/AR-15 ERG AEG should be your next primary! Made with the phenomenal build quality PTS Syndicate has become known for, the Radian Model 1 ERG makes use of the KSC/KWA AEG3+ gearbox paired with the ERG recoil system, giving you violent feedback each time you pull the trigger; perfect for realism fans!

This latest version of the ERG system no longer has the "bolt stop" function but now includes a programmable MOSFET/ETU system. Available functions include pre-cocking, burst mode, trigger sensitivity adjustment, brushless motor mode and equaliser, which from what we can tell means trigger reset adjustment. Setting aside its internals, the Radian Model 1 is outfitted with all of PTS' finest ergonomic upgrades, including the Raptor™ ambidextrous charging handle, Talon™ ambidextrous fire selectors, EPG pistol grip and EPS battery stock, giving you a setup which you'll never need to enhance to run to its full potential!

Compatible with both ERG pattern magazines and standard M4/AR-15 AEG magazines, this is anything but your standard M4 AEG! Its highly modernised receiver and well-designed ambidextrous controls put the Radian® Model 1™ M4/AR-15 ERG AEG in a league of its own, with handling to rival the best and ready for all the most cutting-edge accessories!

Description

If you're getting bored of AEGs but don't want the challenges which come with a GBBR, the PTS Syndicate Radian® Model 1™ M4/AR-15 ERG AEG is ideal. This full-metal M4/AR-15 AEG is based on the real steel Radian® Weapons Model 1™ AR-15 and is flawlessly built with licenced trademarks, as we would expect from PTS Syndicate!

While it is electrically powered, the Radian Model 1 ERG is equipped with the KSC/KWA ERG recoil system, meaning shoulder-thumping recoil with each shot which is sure to put a smile on any shooter's face! The recoil is almost as jarring as a GBBR but the ERG requires nowhere near the maintenance its gas-powered relative requires, is far more economical to run and will shoot far better in standard-issue UK weather conditions!

This newest version of the ERG system is also equipped with a programmable MOSFET/ETU system, providing a faster trigger response than legacy models and the option to set it for pre-cocking, burst mode and brushless motor mode with trigger sensitivity adjustment and equaliser adjustment thrown in for the pros. 

Externally, the PTS Radian Model 1 is a perfect match for the real thing, including the ultra-modern Radian Weapons receiver, Talon™ ambidextrous fire selectors, and the Raptor™ ambidextrous charging handle, with PTS's own fantastic EPG grip and EPS stock standing in for the real steel Magpul used on the original. If you like recoil and top-tier build quality, you'll love the Radian® Model 1™ M4/AR-15 ERG AEG from PTS Syndicate! 

Starting at the front, we can find a birdcage flash hider mounted to the 14mm CCW male barrel threads. The birdcage looks great on the Model 1 but if you prefer a more up-to-date muzzle device, a tracer unit or suppressor these can be mounted easily thanks to the barrel's common 14mm CCW threading. We think a PTS Dead Air Sandman suppressor is the perfect pairing for the Model 1, but make sure you remove the grub screw in the flash hider before attempting to unscrew it. 

Moving rearwards, we come to the M-LOK handguard which is a free-floated design and a perfect match for the real streel Radian Model 1. This handguard is proprietary and designed specifically for the Model 1's unique billet-style upper receiver, boasting a stronger mounting method than standard AR handguards and rivalling true monolithic uppers in strength. 

At the 3, 6, & 9 o'clock positions, we are treated to M-LOK attachment slots which have been officially tested by Magpul and confirmed to be true M-LOK spec. The 12 o'clock position is equipped with a 20mm Picatinny rail which is weight-reduced in the centre to keep the front end light and pointable. This rail meets the receiver rail seamlessly, giving you plenty of space to mount your choice of optical sight while guaranteeing a reliable and repeatable zero. 

Pre-installed on the upper rail, we are treated to a set of PTS Enhanced Polymer Back-Up Iron Sights (EP-BUIS), some of the best iron sights available for Airsoft. These sights are very well made and can be deployed quickly by hand, offering full adjustment for both windage and elevation without the need for tools and the choice of two aiming apertures; a wider one for low-light situations and full auto fire and a finer aperture for bright conditions and accurate semi-auto fire. 

The receiver itself is one of the best-made Airsoft receivers in existence, boasting flawless machining across the design and unique yet well-designed ambidextrous fire controls. The fire selector, a fantastic replica of the real steel Radian Talon™, is positioned just above the pistol grip for easy access from a firing grip, offering SAFE-SEMI-AUTO in its default configuration with engraved bullet pictograms denoting each fire mode. The Talon™ is ambidextrous and an extended design, making mode changes quick and easy for left or right-handed shooters. At the top rear of the receiver, we have the Radian Raptor™ ambidextrous charging handle, offering elite looks and easy HOP-up access from either side of the platform. 

To access the HOP-up unit, you'll need to also make use of the A-DAC bolt catch system, another advanced feature of the real steel Radian Model 1 authentically replicated by PTS. To lock the mock bolt open, simply pull and hold back the charging handle while pressing the lower section of the bolt catch, found on the centre left of the receiver, just above the magazine release. With this done, you can release the charging handle and the mock bolt will stay retracted, revealing the rotary HOP-up adjuster at the front. 

The HOP-up allows you to tune the Model 1 ERG for your choice of ammo weight, seeking the flattest possible trajectory. Once your adjustment is complete, you can hit either the enlarged paddle of the bolt catch on the left side or the A-DAC bolt release catch on the right, just above the mag release to send the mock bolt home with a satisfying "clank". The magazine release is also ambidextrous, offering a standard AR-style release on the right side and an extended lever on the left. While the left side mag release is very firm and somewhat hard to press, the magazine drops free every time but somehow also has minimal wobble. Clearly, PTS has gone to the next level ensuring the mag fit is tight but you can still carry out those super slick Costa-style emergency reloads!

To match the real steel Radian Model 1, the forward assist bulge and mock brass deflector on the right side of the upper receiver have been redesigned to save weight and reduce the chances of snagging. In Airsoft terms, both of these are non-functional but nonetheless essential to complete the realistic Model 1 look. The trademarks of the Model 1 are discrete and professional, showcasing an engraved "RADIAN" above the trigger on the left side and "A-DAC" with "PTS" just below on the right side. Additional laser engraved markings are present on the left side between the upper and lower reading "MODEL1 MULTI CAL S/N: xxxxxxxxHK". 

Moving downwards, we come to the pistol grip, one of the best Airsoft AEG pistol grips on the market, known as the PTS Enhanced Polymer Grip (EPG). The EPG is constructed from Dupont Zytel, a high strength, abrasion and impact-resistant thermoplastic polyamide/nylon, aka, the best of the best when it comes to high-density polymer. With comfortable dot texturing on either side and crackle texture on the front strap and backstrap, the EPG is a dead-ringer for the real steel Magpul MOE grip often found on the real Radian Model 1. 

At the rear of the receiver, we can find the prolific M4/AR-15 buffer tube, offering 6 adjustment positions for the pre-installed PTS EPS stock. The EPS is inspired by several low-profile real steel stock designs but made with Airsoft in mind, meaning plenty of battery space and very easy battery access. To access the battery compartment, simply press the two textured tabs on either side at the toe of the stock, after which the butt plate will pop off, revealing a Deans battery connector inside. We recommend a 7.4V 2000mAh LiPo battery in Crane/Nun-chuck configuration to take maximum advantage of the extra battery space. Please note, the battery for the Model 1 must be installed inside the stock itself and won't fit inside the buffer tube due to the recoil system. 

Amongst the EPS's many tricks are a low profile adjustment lever which is easily accessed from either side, a QD sling socket on each side, ready for QD sling swivels and a grippy rubber butt plate for fantastic all-weather handling. Also present is a conventional footman loop sling slot for strap slings and a comfortable sloped cheek rest similar to a crane stock. The EPS is made from the same fantastic quality Dupont Zytel polymer as the EPG grip, guaranteeing maximum strength and a high-quality finish befitting the metal parts of the Radian Model 1. 

Inside, you'll find KSC/KWA's latest AEG3+ gearbox, boasting a reinforced shell and programmable MOSFET pre-installed. The MOSFET offers trigger sensitivity adjustment and equaliser(trigger reset) adjustment along with pre-cocking and burst mode options. Brushless motor mode is also an option, giving you the ability to upgrade the Model 1 ERG's motor with the latest technology out there. The gearbox shell is also designed with Gate TITAN MOSFET compatibility in mind, requiring no mods to upgrade to this space-age ETU. 

If you're into hard recoil, flawless build quality and unique aesthetics, the PTS Syndicate Radian® Model 1™ M4/AR-15 ERG AEG will definitely put a smile on your face! Being an AR platform while still being unique is enough of a perk, not to mention being equipped with super-slick ambidextrous controls and high-end PTS furniture!
