I can think of a reason why this may be a ridiculous idea, but...... Has anyone any information on using modular add-on weights for recoil reduction/control with rifles? Where would such a weight have to be placed? How about a gunsmith that wouldn't roll his eyes? I'm thinking in terms of making a practical eight to ten pound rifle a fifteen pound rig with a simple bolt on weight. A fifteen pound rig is pretty specialized, but a ten pounder such as I suggest is just a little heavy with a couple of curious holes in it. The ability to pull the weight from the pack and add it when favorable appeals to me for certain specific situations.
