Been lurking around this site for a few days, thought I had better sign up. retired 2 years ago after 44 years in the construction industry, managed to pick up a few nice firearms along the way. A relative new comer to the AR platform. Went thru several AR's in 308, before I found one I like. M&P 10 had some issues with being under gassed after a couple hundred rounds still wasn't as dependable as I thought it should be. Then a POF, it was a 10+ lb. beast, dependable but just to damn heavy. Currently have a DPMS G 2 Recon with a 16' barrel. Runs pretty good, reasonably accurate, weighs less than the POF. Has been reliable. Taken two white tale with it using 150 grn. Federal Fusion factory ammo. Have been interested in the articles about using heavier buffers/springs to lessen recoil. Just want to learn from knowledgeable folks.
