If you prefer the old days when real men carried full-length rifles, you'll definitely be into the Specna Arms SA-B06 ONE™ M16A4 AEG! This full metal M4/AR-15 platform is based around Specna's original ONE™ series M16A4 but now comes equipped with the Kestrel Basic ETU, a programmable MOSFET which is far more advanced than its moniker "Basic" suggests!

The Kestrel Basic offers programmable fire modes including 3-round burst and binary trigger, adjustable pre-cocking, active braking, cycle completion, low battery warning and low/high voltage protection. Put simply, this allows the M16A4 to be set up realistically as SAFE-SEMI-3RND BURST, keeps your gearbox cycling at maximum efficiency and with pre-cocking set, provides an incredibly snappy trigger response ideally suited to rapid double taps. Paired with Specna's standard 509mm 6.03mm tightbore inner barrel and rotary HOP-up unit, this is one of the best-equipped M16A4 AEGs on the market!

Whether you're working on a GWOT-era USMC loadout or you prefer the iconic M16 silhouette to its prolific shorter sibling, the Specna Arms SA-B06 ONE™ M16A4 AEG; Kestrel Basic ETU is the big M4 you need!

  • Full metal construction
  • URX2 style aluminium handguard
  • Preinstalled programmable MOSFET

If you are in the market for an M4/AR-15 optimised for woodland warfare this one would suit you well! The Specna Arms SA-B03 ONE™ replicates the real-world SR-16 rifle, a high-end M4/AR-15 rifle from the US. Like the original SR-16, the Specna Arms version boasts a 10.5-inch free-floated handguard known as the "URX2", an extended handguard with ample rail space, QD sling sockets built-in and perfectly suited to the modern C-clamp grip technique.

On the inside, the SA-B03 has been upgraded to handle stronger springs, sporting a steel quick change spring guide mounted on ball bearings for reduced rotational stress, an aluminium cylinder head and piston head, reinforced steel gears and a lightweight polymer piston with a full rack of steel teeth, plus the added benefit of the programmable Kestrel Basic MOSFET. If you are looking for a base gun for a DMR project this would do the job perfectly thanks to its 16-inch outer barrel and the Enter & Convert™ quick change spring system!

  • High-density polymer/CNC alu handguard
  • 6.03 Tightbore inner barrel
  • HAL¹ ETU Pre-installed - Programmable fire modes

This compact platform is exactly what you need for your close-quarters battles. It is short and lightweight, making it a great asset for those who like to stay nimble during their skirmishes. The Specna Arms SA-C21 CORE™ HAL¹ ETU™ M4/AR-15 AEG has an entry-level price point, with veteran-level potential!

This SA-C21 is rocking Specna's HAL¹ ETU, boasting programmable fire controls and several quality-of-life functions built-in, all for barely more money than the original. The HAL¹ allows you to select binary trigger, AUG mode and sniper delay instead of semi-auto and semi-auto lock, 3-round burst or 5-round burst instead of full auto. Also available are 5 levels of trigger sensitivity adjustment, 6 levels of adjustable pre-cocking, active braking and a low battery voltage alarm. Like the original, the HAL¹ equipped version also has a 6.03mm tightbore inner barrel, giving it above-average accuracy potential and a slight rise in FPS from the same strength spring.
