Hi everybody, this is my first post in the competition shooting section. I've recently found the sport of 3 gun shooting in some American Rifleman magazines, and on 3 gun nation when it was being aired. This is a sport that I would like to be equipped for within the year, I've decided on the shotgun (Winchester SX3 with 10 round magazine extension) and the pistol (Walther P99 40 AS). However, I'm stuck on the rifle. I was considering an AK-47 or AK-74 but then I found out that competitions can reach out to 200 yards, so I've decided not to get one for competition shooting. I'm looking at The Ruger SR-556 and the LWRC M6A2, both in 6.8 SPC with an EOtech 557.G23FTS weapons sight. Is the LWRC worth the extra $500-750? Does the 6.8 SPC bring in too much power? any other suggestions? Thanks for the input!
