  • HAL¹ ETU Pre-installed - Programmable fire mode

The Specna Arms SA-C22 CORE™ HAL¹ ETU™ M4/AR-15 Carbine AEG is the perfect beginner Airsoft rifle, with its preinstalled MOSFET, it is sure to outperform other platforms at a similar price point. This M4/AR-15 AEG follows Specna's "CORE" build standard, featuring a CNC aluminium handguard, alloy outer barrel and suppressor paired with a high density polymer receiver, stock and pistol grip, ideal for skirmishers who like to move fast and maintain high-energy skirmishing all day long.

This, the latest version of the SA-C22 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. Impressive stuff for a beginner-level price point!

Suppose you're looking for an advanced, compact AEG with plenty of features for its relatively low price.

If you like your M4 AEGs simple and effective, the Delta Armory DA-A01 ALPHA™ CQB-R M4/AR-15 AEG is perfect for you! Based on the real steel M4A1 in the shorter CQB-R configuration, this M4/AR-15 AEG is rocking a 10.5-inch outer barrel, putting it in that sweet spot, with enough barrel length to handle most long-range threats while not being too long that close-quarters combat becomes impossible.

 On the outside Delta has added a gunfighter mod.3 style pistol grip, the classic ALPHA™ style stock and an enhanced receiver, complete with gripping texture on the magazine well and a built-in enlarged trigger guard. This gives the now old-school M4A1 base platform a slight facelift without ruining its iconic outline and maintaining suitability for casual and Milsim skirmishes. If you love the M4A1 silhouette but want more modern ergonomics and a shorter barrel length, the Delta Armory DA-A01 ALPHA™ CQB-R M4/AR-15 AEG is the best choice!

  • 6.03mm Tightbore inner barrel
  • High density polymer construction
  • High torque motor pre-installed

If you're ready to start your Airsoft adventure, the NUPROL Delta Pioneer Jackal M4/AR-15 AEG is a great option. Made primarily from high density polymer with steel and alloy trim parts, this build is ideal for younger skirmishers with less physical strength and those seeking a simple and bombproof backup to lend to mates or use near the end of the skirmish day when post-battle fatigue sets in!

Though it may be mostly polymer, this isn't the usual shiny "super-soaker" tier stuff; this is nylon fibre-reinforced polymer, the kind that may well outlast alloy when it comes to endurance. Inside, we are equipped with an alloy version 2 gearbox with 18:1 ratio steel gears running on 8mm ball bearing bushings and driven by a 21K RPM high torque motor; a competitive feature set for a platform at this price!

The inner barrel is also a 6.03mm tightbore paired with a 50° HOP-up bucking and rotary HOP-up unit, ensuring you can reach out and engage at longer ranges with an accuracy advantage using high quality BBs. If you're seeking a compact and sleek AR platform in a beginner-friendly format, the NUPROL Delta Pioneer Jackal M4/AR-15 AEG is a great call!

  • LPEG - Low Power Electric Gun
  • Compatible with standard AEG magazines
  • Perfect for Airsoft skirmishers of the future!

If you have a younger sibling or child who wants to get into Airsoft but they aren't yet old enough for the real deal, this LPEG is ideal to help them learn the ropes! The Umarex H&K HK416 CQB Low Power Electric Gun is designed to cater to the younger market, offering a super lightweight electric powered Airsoft gun which runs at around half the muzzle energy of standard AEG, making it safer and less painful to get hit by but just as fun to use as the full-fat skirmishable models.

Compatibility-wise, this HK416 can accept standard Airsoft AEG magazines and 8.4V NiMh batteries with mini-Tamiya connectors, but both the externals and internals are proprietary and not compatible with standard AEG parts. The good news is that the 20mm Picatinny rails on the receiver and handguard can accept most Airsoft 20mm Picatinny accessories, meaning you can mount a red dot sight and a grip to give this low-cost, low-power, high-fun HK416 the elite look.

M4, AR-15 and M16 platforms are some of the most popular in the Airsoft community. 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. 

If you’re looking for an Airsoft platform to upgrade, an M4/AR-15 AEG is ideal thanks to its wide aftermarket support, customisation options and accessory attachment interfaces. Parts are easy to replace and accessories can be mounted straight away in most cases; perfect for those who dream of their own custom Airsoft gun!
