30" tubes. I recovered the ole girls from a local gun shop.

It is a labor of love and learning.

I am thinking about fabing up an aluminum housing to fit into the back of the stock/hollow that, from the outside, would look like a spacer between the stock and recoil pad but would be hollow and large enough to fill with weight as needed. I have used 1/4" alum as spacers on numerous guns and it adds a pleasant littlest amount of bling. I need 14 1/2 to 15 " of pull so it makes sense to me.
