Ok-so I already do yoga.

The question pertains to my search for a lightweight game gun(6lbs-6lbs 3oz is the target). Everyone I have found so far will need a checkered wood stock addition or a recoil pad of some type to get to my 15"LOP -with the desired drops at comb and heel.

That adds weight at the back end. And, if the gun was "balanced" before the addition, it may not be after the addition.

How do I get rid of the added weight and restore the guns balance?

I have heard of drilling a hole in the butt stock to remove weight. My 12 ga AYA has such a hole. Are there any other tips or suggestions that you all can offer besides placing a custom order for a new shotgun, which I could do for an AYA, or having a new stock made for the gun?

Thank you.
