As a retired Msgt and Viet Nam Vet, I carried a M-16 in Nam and was not very impressed in the weapon or the .223 cartridge, though it was in its early days in 1965. Then I carried a bolt action Remington 700 BDL, 30-06 but got kind of tired of the sore and bruised sholder while wearing "t" shirts, my Remington had a solid but plate. My son built his own .223 AR-15. While trying to purchase a new Winchester 1886, 45.70 with a 26" octogen barrel (at around 12 pounds) but I was just a little late, it was sold to another bidder. I had been reading about the piston driven Ruger SR-762 and thought it was very interesting. The AR platform is extremely ergonomic and since it was chambered in the Winchester .308 cartridge, which is very available, and with some of the hotter loads has velocities approaching thperformance of the 30-06 with out the recoil and even had better accuracy I bought one. I am very satisfied with the weapon, even the higher price. Of course, like my Harley, it can tend to be a money pit with all the accessories involved
