The principle of operation of the carbine
The DDM4 MK18 is based on a classic gas system developed by ArmaLite. It uses gunpowder gases that, through a hole in the barrel and then a gas tube, enter the interior of the slide, expanding it and unclamping it. The advantage of such a system is the reduced number of moving parts, reduced recoil sensation and smooth operation of the breech. The weapon is bolted by rotating the breech with 6 symmetrical bolts. The breech and trigger chamber, standard for AR-15 carbines, is made of milled aluminum coated with a durable coating created by the anodizing process.
Safeties and manipulators
The carbine has two types of safety features. The primary one is a winged safety located on the left side of the trigger chamber, just above the thumb. It can be easily operated by the shooter without taking his hand off the grip. The second safety is an internal lock that prevents the shooter from firing when the lock is not engaged.
Compatibility with military specifications
The weapon was made in Mil-Spec-compliant specifications, so you can easily replace the buttstock, pistol grip, foregrip, manipulators, trigger tongue with others. The model is an excellent choice for those who plan to make intensive changes to the internal parts of the weapon. It will also be perfect for those beginning their adventure with dynamic shooting.
Self-supporting carbine barrel
The Daniel Defence DD4 carbine is equipped with a thin 10.3" long, chrome-plated and cold-forged barrel with a typical 1:7 threaded profile . Its surface has been anodized to protect it from factors like corrosive effects of powder gases and water. The barrel ends in a thread with a factory-installed flame suppressor. The 5-screw front bed has 22mm rails with angles at 3, 6 and 9 o'clock, with which you can easily install additional accessories like a flashlight, foregrip, angle grip or additional sighting device. Also, a 22mm Picantinny rail is drawn across the entire length of the lock chamber and bed.
