Where is the CG on an AR 15?

[Capt. Speirs]

Here goes, where is the optimum center of gravity on an AR 15? I am trying to balance my AR. I suppose it has to do with what the gun is used for. My first build I designed for close in with some reach. My second will be a large caliber long barreled AR.

too many different variations of ar15s i think you have to just kinda measure yours on your own

The optimum center of gravity would probably be the midpoint between your two main points of contact while standing, which I would consider your forward hand and shoulder. This would of course vary depending on where your forward hand is. If you're talking about a bench precision rifle, you can push it forward more and make it front-biased.
