If you're searching for a super flexible M4/AR-15 AEG with an ultra-modern aesthetic, the Delta Armory R15 FREYA™ 13" M4/AR-15 AEG should suit you perfectly. Boasting a full metal build on the outside and pre-upgraded internals inside, the FREYA's party trick is the new Delta Armory EAGLE ETU, offering more programmable functions than previous versions and allowing you to run the FREYA™ as a DMR with semi-auto only and a stronger spring and quickly swap the spring and fire control options for a CQB skirmish the next day. 

Inside, we are treated the new Delta Armory EAGLE programmable ETU/MOSFET, offering even more programmable functions than the original Delta ETU. The EAGLE allows for 3 or 5-round burst mode, binary trigger, sniper delay, AUG mode, semi-auto only and precocking to be programmed in using the fire controls of the AEG itself. If you're looking for a lesser-seen design with AR compatibility, the R15 FREYA™ 13" M4/AR-15 AEG from Delta Armory is a fantastic option with more than its fair share of perks!

Description

If you're looking for an M4/AR-15 platform that can do it all, the Delta Armory R15 FREYA™ 13" M4/AR-15 AEG is pretty darned close! This full metal M4/AR-15 AEG is externally based on the real steel GrandPower Firearms FREYA™ and is kitted out on the inside with Delta Armory's best MOSFET yet.

The new EAGLE ETU/MOSFET is the star of the show, offering unprecedented programming options using only the fire controls of the AEG itself. Options include 3 or 5-round burst mode, binary trigger, sniper delay, AUG mode, semi-auto only and precocking. Thanks to its quick change spring system, the FREYA™ can be an assault rifle one day and a DMR the next!

Starting at the front, we can find a lovely replica of the real steel "SF" muzzle brake, designed in the real world to reduce muzzle climb under rapid fire. The brake looks fantastic and suits the speedy styling of the FREYA™ perfectly but it can be swapped out for any 14mm CCW male-compatible muzzle device, including tracer units and suppressors, if you fancy a different look or an instinct-aiming advantage in low light. 

The outer barrel of the 13" FREYA™ is 14.5 inches in length, matching the barrel length of real steel US Army issue M4A1 rifles and providing the ideal barrel length for multi-role Airsoft. Surrounding the barrel, we are treated to a uniquely lightweight skeletonised handguard boasting M-LOK slots a the 6 o'clock position and a 20mm Picatinny rail running along the top. The sides boast triangular weight-reducing ports, with 2.5 M-LOK slots a the front for additional M-LOK accessories. The skeletonised handguard makes the front end of the FREYA™ easy and fast to point, making it an asset to a fast moving playstyle. 

On the top of the handguard, we can find our front flip-up iron sight which is spring-loaded, requiring a press on the textured surface at the rear to deploy. The rear sight is mounted to the receiver rail and functions the same way; simply press the button and up it pops. Elevation adjustments are applied on the front sight using an AR-15 front sight adjustment tool and windage on the rear sight via the dial on the right side. The rear sight also features two apertures, a fine one for bright conditions and accurate semi-auto fire and a wider one for low light scenarios and full auto. 

Following the handguard, we come to the receiver which is constructed from alloy with a unique skeletonised design based on the real steel GrandPower R15 FREYA™ receiver. Practically everywhere that weight can be reduced, it has been, resulting in an ultra-modern look and superb handling and weight distribution. The forward assist button has been deleted, just like the best of real steel AR platforms, and the mock brass deflector is considerably smaller than mil-spec M4s, further reducing weight. As we would expect for a modern AR, the receiver boasts a 20mm Picatinny rail, meaning you can mount a red dot sight or scope straight away with no extra adapters needed. 

The layout of the controls matches other M4/AR-15 platforms, meaning no need to retrain if you are used to a standard AR despite the unique receiver of the FREYA™. The fire selector is positioned just above the pistol grip and offers 3 modes of fire; SAFE, SEMI and AUTO, with a 90-degree throw between each mode. This makes the selector easy to switch, but not so easy that it can be knocked out of position accidentally. Each mode is denoted with laser-engraved "SAFE-FIRE-AUTO" markings. The magazine release is on the right side of the magazine well and is accessible for a right-handed user with the tip of the trigger finger.

Pulling back the charging handle, located at the top rear of the receiver will open the dust cover and retract the mock bolt carrier to allow access to the rotary HOP-up adjuster. This is the latest HOP-up unit design for the M4/AR-15 and provides finer increments of adjustment and holds its setting more effectively when compared to the older gear style HOP-up unit. The charging handle has an extended latch for easier access, allowing even those with thick gloves to access the HOP-up unit, though you may need to take off a glove to turn the adjuster! 

The pistol grip of the FREYA™ 13" boasts a refined grip angle for greater comfort when shooting with the stock fully collapsed and in more modern shooting stances. Each flank of the pistol grip includes fine crackle texturing, with additional linear texture on the front and back straps for perfect wet weather handling. The trigger is a "flat" trigger with a short finger ledge and textured front, making it ideal for pumping out rapid semi-automatic shots in CQB. 

At the rear of the receiver, we come to the steel CQD style sling plate, which offers ambidextrous functionality with single-point slings; perfect for left or right-handed shooters. The steel construction of the sling plate practically guarantees even if you mount a massive rifle scope, PEQ box and RunCam, the sling plate will be strong enough to support the weight. Following the sling plate, we come to the good old AR buffer tube, constructed from alloy and offering 6 adjustment positions for the pre-installed stock, or any other M4/AR-15 AEG stock you choose to mount!

The stock itself is a slimline design unique to the latest releases from Delta Armory. Featuring a QD sling socket on either side, a low-profile adjustment lever on the bottom together with conventional "footman loops", aka sling slots, the highlight of this stock is its rubber butt plate featuring lattice checkering and an angled section at the toe for providing grip in the most modern shooting stances, with or without body armour. If you have a preferred stock design, the stock can be swapped for alternative M4/AR-15 AEG stocks if you want to change up the looks!

The buffer tube also serves as the battery compartment for the 13" FREYA™. To access the battery compartment, you will need to pull the stock adjustment lever (located on the bottom of the stock) out and hold it in place, after which you can slide the stock off the buffer tube, revealing a Deans/T-Plug battery connector inside. We recommend a 7.4V 1300mAh LiPo in stick configuration for the R15 FREYA™ though you may need to keep the stock extended to fit this battery inside. Delta Armory recommends a LiPo battery measuring 1.4 x 1.9 x 10 cm approximately for full functionality of the sliding stock. 

Inside, we are treated to the new EAGLE ETU/MOSFET system, offering more programmable options than ever before, including 3 or 5-round burst mode, binary trigger, sniper delay, AUG mode, semi-auto only and precocking. The ability to program this wide variety of modes using the trigger and selector of the gun itself gives the FREYA™ 13" the edge over practically any other platform in this price range. 

If you're in search of a light and fast AR that can be an assault rifle one day and a DMR the next, the Delta Armory R15 FREYA™ 13" M4/AR-15 AEG is the one to go for. Its combination of programmable controls including sniper delay and semi-auto only paired with a quick change spring system makes this a fantastic DMR basegun!
