Others Heavy AAA build thoughts

I have been considering adding some weight to my EVOL. Having read many threads on the net It sounds like a good idea and will improve accursary/ groups. Most threads lean to adding to the butt but with the full front rail on the EVOL it would be simple to add and change weights as I field test this idea.
My, as of now plan, is to remove the butt stock to access the buffer tube, I would roll out an amount of Duct Seal to the required diameter and cover it with saran wrap. I would need to make sure it wont interfere with anything which I dont believe it will. I have not measured how long the buffer tube is and the amount of weight would be. I am thinking around 1 pound or a tad more.
So, what are your thoughts here, good or bad, looking for advice. A 1 pound bipod is fastened to the barrel rail right now to see if It helps or hurts.

The internal buffer tube dimensions on my original Magpul PRS stock are 1" × 9.5" which comes to 3.1 lbs of lead per an online calculator.

Here's a more precise online calculator to play around with.

Cylinder Weight

The Weight of a Cylinder calculator computes the weight (mass) of a cylinder based on the radius (r) and height of the cylinder (h), and the density of the material (mD). NEW: Weight of Steel Cylinders using millimeters and density of steel.

Appreciate the numbers, that will be a great help! I will check mine and see if they are the same then proceed. I still want to fill with Duct Seal for a dry run

My horrible "mock up" of what I was thinking. I am going to draw something that I can put dimensions on and what not. But a basic idea.

The blue box is where the rail would be mounted. Could mount through the bottom plate, and mount the arca rail to the frame.

I checked mine and it is 1.00ID x 7.5 inches long

The calculator says you're still going to be able to get around 2.4 lbs of lead in there. What you could get, which would be the heaviest readily available metal, is pure tungsten TIG welding rod (the green painted tip). They come in 7" lengths and weighs more than lead. These rods at 7"" and packing the buffer tube full, would be adding around 3 lbs.

Thank you for your input. I had leftover Duct Seal and used that tonight. I used a piece of PVC to roll it out, making 3 pieces that were 2.5 inches wide. I had a stash of 45 cal slugs and placed 4 of those end to end and rolled it up till it was 1 inch OD. Then I placed each one on a piece of Saran wrap and rolled it to help keep it from sticking to the buffer tube. All 3 were placed in the tube and I used a dowel to tamp them in snuggly. The total weight gained was 14 oz which will do for now. Let the testing begin and see what we can see.

Sounds like a good start. I don't see how weight can hurt a rifle if it's shot rested off a bench or so. As long as it's not touching the barrel harmonics shouldn't be affected in a negative way. Or positive really. But should make the gun move less when trigger is pulled helping keep on target and less human error. At least what I've been able to tell.

Was playing with a few designs and wound up not liking any of them. That got me to thinking about the weight on the Paradigm. Being as the stock is held on with 1 bolt, I don't want to stress that point up and put to much weight on the forend as well.
