6.03mm Tightbore inner barrel
Pre-upgraded version 2 gearbox
High-density polymer construction
If you're in the market for an affordable M4/AR-15 AEG with programmable fire controls and a lightweight polymer build, the Delta Armory DA-C06 CHARLIE™ Silent Ops M4/AR-15 AEG is what you need. This integrally suppressed M4/AR-15 is rocking the sneaky "Honey Badger" look and is equipped with a quad rail handguard for all your accessory needs. Unlike a real suppressor, the integral example installed on the DA-C06 CHARLIE™ serves to conceal an extended 6.03mm tightbore inner barrel, giving this short and sneaky-looking platform surprising long-range effectiveness. 
As with the other offerings in the Delta Armory CHARLIE™ range, the tightbore inner barrel is paired with a rotary HOP-up unit, and a pre-upgraded gearbox featuring an SHS tappet plate and piston, 7mm bushings and a quick change spring guide. This gives you a respectable pre-upgraded feature set straight out of the box, with plenty of room for further upgrades thanks to full Tokyo Marui compatibility. Whether you are new to the sport or a veteran skirmisher looking for a sneaky backup platform, the Delta Armory DA-C06 is the best AR in this style and price range we have seen!
