  • Full metal construction
  • Zion Arms Nebula ETU / MOSFET pre-installed
  • CNC 7075 T6 Aluminium receiver & handguard

If you're getting tired of the standard shaped M4/AR-15 platform the Zion Arms R15 should reignite your passion for the platform. This AEG is based on the real steel R&D Precision PW9 with its aggressive muzzle brake and dynamic looking M-LOK handguard but uses a unique 5.56-style receiver so you can use your existing M4/AR-15 AEG mags. The amazing build quality of this replica cannot be overstated; with a CNC machined 7075 T6 aluminium receiver and handguard, plenty of steel and gorgeous high density polymer furniture, the R15 weighs in at a mere 2.1kg despite its full metal construction.

While the externals are lightweight and speed-oriented, the internals take this theme to the next level. The inner barrel is a 6.03mm tightbore, meaning improved accuracy and consistency, the bushings are 8mm and equipped with ball bearings for friction-free performance and a smooth gearbox sound, and a high speed motor coupled with the advanced Zion Arms Nebula ETU/MOSFET provides its astonishing rate of fire and trigger response. The Nebula also allows you to program the trigger for burst mode, binary trigger and semi-auto only, giving the R15 what it needs to compete in the age of MOSFET-equipped AEGs!

  • L119A2 Replica - Ideal for SAS/UKSF loadouts

If you're working on an L119A2 build for your SAS/UKSF loadout, why bother? The Rossi L119A2 Neptune SAS 10.5" AEG with MOSFET is a fantastic replica of the real steel L119A2 boasting full metal construction, a programmable MOSFET/ETU system and pre-upgraded internals, all assembled and ready to rock with no compatibility worries and no technical headaches!

Externally, the Rossi L119A2 is a very close match for the real thing, with the only compromise being its non-monolithic receiver design. The real thing has a monolithic upper, but the only available Airsoft replicas have a four-figure price tag and come as a kit, requiring a lot of technical expertise and other parts to complete the build. 

With the Rossi L119A2, you are treated to some impressive stuff on the inside as a bonus. The version 2 gearbox shell is reinforced and equipped with 16:1 high-speed CNC steel gears, a ball bearing equipped quick change spring guide, a CNC aluminium nozzle, a polymer piston with a full steel tooth rack and a ball bearing piston head, resulting in top-notch reliability, improved rate of fire and easy spring changes for power tuning. The pre-installed MOSFET makes thing even sweeter, offering a wealth of programmable fire mode options, adjustable pre-cocking and trigger sensitivity with active braking to top it off. 

If you want the Obiwan Nairobi look for your next skirmish, the Rossi L119A2 Neptune SAS 10.5" AEG with MOSFET is the primary you need!

  • Full metal construction
  • Professionally tuned by Bolster Armouries
  • Gate ASTER MOSFET & Warhead 27K Base motor

Introducing the Bolster Tuned TTI JW2 M4/AR-15, a professionally upgraded AEG platform based on the EMG TTI JW2, boasting many of the biggest names in aftermarket upgrade parts put together by the same talented techs that brought you Bolster Armouries. Unlike other custom Airsoft gun services, Bolster Tuned platforms are all pre-built and ready to ship the next day with no lead time!

The Tuned JW2 builds upon the already impressive base platform and irons out all the creases, adding in a plethora of low friction, high strength enhancements to the gearbox itself. These include an FPS Softair O-ring equipped air nozzle and carbon fibre reinforced tappet plate, Bolster's own EZO bearings, M115 spring and stainless steel sector gear screws, a Laylax Hard Selector plate and the gorgeous Gate Quantum flat blade trigger.

The Quantum is paired with the incredibly advanced Gate ASTER MOSFET, offering 250 different trigger sensitivity settings, pre-cocking, programmable fire controls and much more via the Gate USB link or Gate Control Station app. To deliver the speed it needs to bury the original EMG CYMA Platinum JW2, the Bolster team saw fit to install the Warhead Base 27K Brushless motor, providing unparalleled heat dispersion qualities and speed to rival the very best.

With upgrades added and work done, the price has increased, but by a far smaller margin than it would if you took a stock JW2 to a technician and paid for this amount of work to be done. Finally, we can pick up and play with an exceptionally well-built AEG with all the fine-tuning necessary for exceptional performance already complete, and done with care, to an exacting standard. When we tested this AEG we were flabbergasted. 348 FPS on the dot with remarkable consistency, 60m+ effective range and an absolutely scary rate of fire of 25 rounds per second using an 11.1V Lipo; more than enough to outshoot anything else you can buy off the shelf!

At Patrol Base, we have a great selection of these rifles and their variants, including US Army M4A1 and M16 replicas. Not to forget the highly popular MK.18 MOD.1 rifle, an iconic AR-15 design used by Delta Force and the US Navy SEALs!

From gas-powered GBBR M4s with exciting recoil to high-performance AEG M4s which shoot perfectly in any weather conditions, we have an M4/AR-15 platform to suit all skill levels and playstyles, from CQB specialists to long-range Designated Marksmen.
