Daniel Defense® MK18 SA-C19 CORE™ - Chaos Bronze

The carbine has engraved licensed markings of Daniel Defense® - a firearms manufacturer from the USA, which since 2002 specializes in providing various variants of the AR15 and accessories, also on special requests by USSOCOM. 

The receiver, the buffer tube and an SF stock that holds the battery, as well as the pistol grip, were made of nylon fiber reinforced polymer. Remaining components such as the barrel, RIS handguard, flash hider, enlarged charging handle and tactical sling swivels were made of metal (parts made of steel include the screws, pins, shell ejection window and mock bolt carrier). 

The replica’s parts are aligned very well and the User will not experience any loose spots between the lower and the upper receiver. The use of a light polymer receiver allowed for a reduced weight, which makes it very suitable for dynamic games or long-lasting mil-sims. 

What’s more, the fiberglass reinforcement makes the receiver also more durable than polymer and metal receivers.  The replica is fully compatible with LiPo and LiFe batteries. 

Due to a base muzzle velocity of ~380 FPS provided by the main spring installed by default by the manufacturer, the replica is perfect for operating on a medium range. The set also includes an M90 spring, which allows reducing the muzzle velocity to ~310 FPS and as a result to adapt the replica for close-ranged and indoor operations.  

The gearbox contains 8 mm slide bearings as well as shimmed steel gears based on them. The system is secured with four anti-reversal latches. A light, made of polycarbonate polymer piston is equipped with a full steel strip, in order to increase its durability. Also, implemented were a type 0 cylinder and a steel circuit-breaker, as well as a precise rotary Hop-Up chamber. 

A carefully made Rotary Hop-Up chamber splendidly cooperates with a high-quality precision barrel with a diameter of 6.03 mm. The implementation of a precision barrel increases the replica’s range and accuracy. One must remember to use high-quality 6 mm BBs.
