Pro2A Tactical 16" 5.56 NATO Non-Reciprocating Side Charging Complete Upper

The Pro2A Tactical non-reciprocating side charging complete upper is the drop-in route to a true left-side-charging AR-15. It ships built on a Gibbz Arms G4 billet upper receiver, with a 16-inch Melonite 5.56 NATO barrel, an M-LOK free-float handguard, and a non-reciprocating side charging handle; the bolt carrier group is a selectable option (Nitride or Nickel Boron), so add one if you do not already have a spare. Bolt it onto any standard AR-15 lower and the rifle is ready to run.

The defining feature is the non-reciprocating side charge. The handle sits on the side of the Gibbz G4 receiver and does not move during the firing cycle, so it stays clear of a mounted optic and lets the shooter cycle the action without breaking the firing grip the way a rear charging handle forces. Running the bolt from the support-hand side helps left-eye-dominant shooters, prone shooting under a magnified scope, and clearing malfunctions with glass in the way. The Gibbz G4 receiver is the platform side chargers are most often built on, and the Melonite barrel finish resists corrosion and wear.

This is the complete-upper answer for buyers who want a non-reciprocating side charger without sourcing a Gibbz receiver, barrel, rail, and bolt separately and assembling them. Pro2A sells the 16-inch 5.56 non-reciprocating side charging upper direct at a $639.99 special price. The 1/2x28 muzzle threads accept a 5.56 suppressor or any standard AR muzzle device.
