Davidson Defense 'Eagle Eye' 8.3-Inch AR-15 9mm Nitride Pistol Complete Upper Build
The Eagle Eye Complete Upper is built around an ELD Performance 8.3-inch 9mm AR-15/AR-9 barrel in a medium profile with a 1:10 twist and a Nitride finish, paired with a Davidson Defense Enhanced Pistol Caliber AR-15 billet upper receiver and a Gauntlet Arms "Ace Series" 7-inch M-LOK free-float handguard. It ships complete, with a United Defense 9mm (9x19) bolt carrier group and a Recoil Technologies mil-spec charging handle, so the builder receives the core working components of an AR-9 upper in one package. The compact 8.3-inch barrel keeps the front end light and quick to handle, and the 1:10 twist suits a wide range of 9mm bullet weights.

Barrel and Muzzle
The 8.3-inch ELD Performance barrel is built in a medium profile and chambered in 9mm, with a 1:10 twist rate suited to a wide range of 9mm bullet weights. It is finished in Nitride, a surface treatment that adds hardness and corrosion resistance while leaving a clean, matte black look. The muzzle is threaded 1/2x36, the common thread pitch for 9mm devices, and carries the included Recoil Technologies 9mm A2 birdcage flash hider.
Upper Receiver and Handguard
The upper receiver is a Davidson Defense Enhanced Pistol Caliber AR-15 billet unit, built specifically for pistol-caliber applications. It is paired with a Gauntlet Arms "Ace Series" 7-inch M-LOK free-float handguard. As a free-float design, it leaves the barrel free of handguard contact, and the M-LOK slots give the builder room to mount lights, grips, handstops, and other accessories wherever the setup calls for them.
Bolt Carrier Group and Charging Handle
The included United Defense 9mm (9x19) bolt carrier group is built for pistol-caliber AR operation. It is paired with a Recoil Technologies mil-spec AR-15 charging handle, completing the core working components of the upper.
Compatibility
This upper is built for AR-9 platforms chambered in 9mm (9x19). Material and finish of the upper receiver and handguard, ejection port door and forward assist configuration, and the lower receiver magazine well pattern needed to match the bolt carrier group's magazine compatibility were not supplied with this listing and should be confirmed before purchase.
