If you're into modern military firearms, you'll love the Delta Armory DA-C09-EGL CHARLIE™ 10" M-LOK M4/AR-15 AEG! Inspired by the real steel L403A1/KS-1 recently issued to the Royal Marines, the DA-C09-EGL is a slightly shorter variant closer in length to the KS-3, though at a glance, it makes the perfect stand-in for the L403A1. On the outside, the DA-C09-EGL is made primarily from high density polymer with an M-LOK handguard, 14mm CCW threaded barrel and 20mm Picatinny railed receiver, ready to be kitted out!
 
While the DA-C09-EGL is similarly equipped internally to the original CHARLIE™ series, the EAGLE™ ETU adds a whole new level of functionality. Using only the trigger and fire selector of the gun itself, you can program the EAGLE™ for burst modes of various duration, binary trigger, sniper delay, semi-auto only, AUG mode, pre-cocking, trigger sensitivity and active braking, giving you an incredibly advanced M4 AEG for an entry-level price.
 
Also inside the DA-C09-EGL is a 6.03mm tightbore inner barrel paired with a rotary HOP-up, offering superb performance at long range and the ability to tune for different ammo weights. If you're after a low-cost, high-performance M4/AR-15 platform which is ready to rock with the most modern accessories, the Delta Armory DA-C09-EGL CHARLIE™ 10" M-LOK M4/AR-15 AEG is one to watch!
