Description
If you're looking for an M4/AR-15 platform with the iconic MK18 quad rail and an ultra-modern receiver design, this is the one! The R15 FREYA™ MK18 M4/AR-15 AEG from Delta Armory is full metal and externally based on the real steel GrandPower Firearms FREYA™ paired with the MK18 quad rail made popular by US Navy SEALs, Delta and the rest of the tier 1 gang.
Inside, 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™ MK18 can be an assault rifle one day and a DMR the next!
Starting at the tip of the 10.5-inch alloy outer barrel we are met with a birdcage flash hider which conceals 14mm CCW male threading beneath. The birdcage suits the MK18 MOD.1 build well, but if you are going full SF with this rifle you will be happy to learn it can accept any tracer unit or suppressor which mounts to the common 14mm CCW male threading. A KAC or SF-style suppressor or tracer would be perfect on this rifle!
The handguard begins practically immediately following the flash hider, being 10 inches in overall length. This handguard is a great replica of the real steel MK18 MOD.1 handguard and boasts 20mm Picatinny rails machined in at the 3, 6, 9 and 12 o'clock positions along the full length of the handguard. The lower section of the handguard can also be removed, leaving the bare barrel exposed to allow an M203 grenade launcher to be mounted in the most realistic way possible, just like the real thing. Whatever you plan on mounting to your primary, this MK18 can take it!
The upper rail of the handguard meets the receiver rail seamlessly, providing a massive 16 inches of uninterrupted rail space along the top; perfect for optical sights of any length. 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 MK18 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, the new EAGLE ETU/MOSFET system offers more programmable options than ever before, along with electrical efficiency improvements for a stunning trigger response and a respectable rate of fire. The ability to choose 3 or 5-round burst, binary trigger, sniper delay, semi-automatic only, AUG mode, trigger sensitivity settings and active braking levels give the MK18 FREYA™ the edge over practically any other platform in this price range.
If you appreciate the combination of a rock-solid military-style quad rail paired with a unique weight-reduced receiver, the Delta Armory R15 FREYA™ MK18 M4/AR-15 AEG should be right up your street. Built like a tank on the outside with the new Delta Armory EAGLE ETU/MOSFET, the FREYA™ MK18 is the perfect hybrid of military and civy!

Joule Charts
Special Instructions
These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
