Full description


The MK18 is another Gun that has an almost-cult following, due to it being a current issue for Special Forces, and also due to the beautiful 20mm Rail System. This replica features a fully licensed Daniel Defense MK18 Rail System with numbered Rail Slots and all the appropriate markings, which, for the price, makes this an exceptional offering.

The Gun is constructed to the usual quality that Specna Arms pride themselves on, with an Alloy Outer Barrel Assembly, Flash Hider, Handguard and Buffer Tube. The Receiver, Pistol Grip and Stock are made from a Nylon Fibre Reinforced Polymer which keeps the Gun lightweight, but also has some flex so that it can survive abuse. Various trim components around the Rifle (such as Screws, Ejection Window and Mock Bolt Carrier) are made from Steel to ensure their longevity.

The Outer Barrel features a Birdcage type Flash Hider which can be unscrewed to reveal a 14mm CCW Thread for Suppressors, Tracer Units and other Muzzle Devices. The 20mm Rail System is Daniel Defense licensed as mentioned, and features Numbered Rail Slots as well as all the markings that should be on the real thing. The Receiver also has a 20mm Rail which comes with a set of Flip-Up Ironsights installed out of the box. The Receiver features Daniel Defense trademarks, as well as typical AR Platform Fire Controls, such as a Safe/Semi/Auto Fire Selector. The Sliding Stock will move to one of Six Positions, to suit all shapes and sizes of user, and is also where your Battery should be installed. Simply squeeze the tabs at the rear of the Stock to remove the Rubber Butt Pad, and access the Mini Tamiya Connector inside. The Stock also has a QD Sling Socket for the installation of a Quick Release Sling Loop.

Internally the Gun features a Rotary Hop Unit, which can be accessed by pulling back on the Charging Handle. This allows you to apply backspin to your BBs and theoretically improve range and consistency, when paired with the right BB weight and HOP settings. The other major feature of this RIF is the ESA™ Quick Change Spring System, which allows you to rapidly change the Main Spring of the Gun without having to disassemble the Gearbox. This is a massive advantage to those who play at multiple sites with different power limits, or those who want the option of quickly changing over to DMR (Designated Marksman Rifle) rules. Simply remove the Stock and Buffer Tube to gain access to the Spring Guide. Other internal components include: 6.03mm Inner Barrel, Shimmed Steel Gears, 8mm Slide Bearings, Four Anti-Reversal Latches, Full Steel Rack Piston and a Type 0 Cylinder.

Included in the box is the Gun itself, a 380rnd High Cap Magazine, 20mm Foregrip and User Manual. If you're looking for a rock-solid and reliable First Airsoft Gun, or you're a regular player who wants a dependable backup or a step up in quality for their next gun, the Specna Arms Daniel Defense MK18 SA-C19 CORE is perfect for the task.
