I had not seen this thread before and now I know I am not the only one to bring up threads that are still inspiring. I don't have anything to prove, I try to make rifles comfortable to myself. Sometimes, they wind up heavier. Granted, like the most recent post said, in so many words, you don't need an 18 pound F-Class ready rifle to go hunting and I would recommend against it. Especially if you are hunting on public land or back country for elk. Both require a lot of walking. As opposed to a shooting competition where you roll your hard shell case from the parking lot to your position in the firing line.
My Windham Weaponry Dissipator M4A3 (5.56) was never meant to hunt with, though I could feral hog hunt and people in my area do that. There is a service that has helicopters and they rent you full auto AR-15s and you hunt hogs in the pastures, from the air. I think you have to bring your own recording of "Gimme Shelter" by the Rolling Stones or "Fortunate Son" by Creedence Clearwater Revival. That one still has the iron sights on it and I like it that way better than any optic for that small a range and rifle.
And I have a Mossberg Patriot .308 Win. I ended up putting that in an MDT LSS Gen 2 chassis and folding stock adapter and SCS adjustable stock. And a 35 oz 5-25X56 scope on it.
And then I have the Mossberg MVP Long Range 308 with the 20 inch medium bull barrel and wooden stock and another big scope and it already has adjustable cheeck. And it is kind of heavy. I have carried it hunting but it was really meant to be a varmint rifle. You set up at the edge of a farm field and pick off woodchucks and it was first chambered in 5.56. Mine is in .308 .
Then I have a Windham Weaponry R16SFST-308 semi-auto (like an AR-10) and a big scope on that and a Magpul PRS Gen III adjustable scope. Probably weighs about 14 pounds - ish, the heaviest that I have. Super accurate. The Patriot, LR-308, and the R16 all have bipods. I always felt you needed them.
Then I changed my mind. My newest and favorite hunting rifle is the TC Center Compass II in .308 Win (my favorite cartridge). Still a heavy scope. I had one of Vortex Diamondback Tactical 6-24X50 scopes on it but now, I have the Arken SH4 Gen 2 4-416X50 on it. Still about 30 ounces or so for the scope. At the range and public hunting land, I am not getting much past 10x on magnification to get the right clarity. So, now, I get more light and field of view, which I like. Plus a little illumination, which I also like. I also changed recoil pad. They have a cushy one on there but I changed to a Falcon Strike hydraulic. And, to adjust for cheek, I put on a Goda Grip cheek pad. Then added to with craft foam and vet tape that I got from Amazon. Very comfortable and probably around 10 pounds.
Find what is comfortable and works for you. For some guys, the inexpensive Boyd At-One stock is the way to go.
