Thanks for the video. With the back issues, you may wish to look at getting an AA Tripod for shooting and of course the 308 will work great off the bipod for longer distance shooting.I finally got to shoot my new toy. It's a smooth shooting rifle. My only complaint is the weight. Its a pretty heavy. Especially the long .308 barrel. .223 has basically no recoil. .308 is very mild. I have neck and shoulder problems so I was a little intimidated by the .308 kit ,but holding the gun up to shoot bothers me much more than the recoil. The recoil is no worse than an AK if that bad.
