GibbzArms side charge uppers build parts

Gibbz G4 Upper left handed build

We have FINALLY received the final parts and are ready to start assembly of two AR-15 uppers that we have been drooling over for the past several weeks. I wouldn’t normally post the pre-build pictures, but these builds have so many cool parts from great brands that I had to share.
In case you have not noticed, these Gibbz Arms G4 Side Charging uppers don’t use a standard AR-15 charging handle. The biggest ergonomic downfall of the M-16/AR-15 and similar rifles, IMHO, is the position of the charging handle, which requires the operator to break cheek weld and lose sight picture in order to cycle the charging handle. The side charging handle on the Gibbs Arms upper fixes this.

One great thing about the Gibbz Arms G4 Side Charge uppers is that they use a standard AR-15/M-16 bolt carrier group. Gibbz Arms supplies a replacement cam pin that works with their upper. It just has to be swapped into the BCG, which is a 1 minute job (if you are slow, like me).

  • Standard A2 Bird Cage muzzle device (for now)

As you can see, we have already dry fit the parts, and even mounted the JP Enterprises handguard build on our JP-15 lower for photos.

What sights and/or optics should we put on these builds?
