If you’re looking for a mid-length M4/AR-15 platform kitted out with full metal externals and a programmable MOSFET for a remarkable price, your best bet is the DA-A19-EGL ALPHA™ TEMPEST 1 M4/AR-15 AEG from Delta Armory! Being an AEG of the Delta Armory ALPHA™ line, the DA-A19-EGL TEMPEST 1 is considerably pre-upgraded straight out of the box, boasting a reinforced gearbox shell, SHS piston with a full steel tooth rack, a quick change ball bearing spring guide, and a 6.03mm tight bore inner barrel paired with a rotary HOP-up unit for impressive long-range effectiveness. 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 DA-A19-EGL can be an assault rifle one day and a DMR the next! Starting at the front end we can find a pre-installed birdcage flash hider at the tip of the 14.5-inch outer barrel. Both the barrel and flash hider are constructed from alloy, and the 14.5-inch outer contains an impressive 380mm 6.03mm inner barrel, making the TEMPEST 1 a fantastic starting point for a DMR build. The 14mm CCW threading also allows you to mount a tracer unit for a low-light instinct aiming advantage or a suppressor to add that sneaky styling!
