Its been a few years since Ive had one in 556 my last was my NRA high power rifle , Yes it was exceeding accurate maybe that spoiled me ,Been doing some reading and research on whats available and exactly what I want in my next one . What I'm thinking is just a basic lightweight rifle or carbine no rails or float tubes ect ect. . Ive read some of the reviews and shooting experiences on several different AR related forums and Im not to encouraged on the accuracy of alot of them ,most were tested at only 50-100 yds and like I said I wouldnt be to excited about the results but they seemed to be OK with it (2-4 moa 5 shot groups ) Like I said maybe I got spoiled with a match rifle? Has any of our members here have experience with lightweight barrels ? what kind of results are you getting on average on a standard AR barrel in a standard rifle? Dont really want to spend 6-700 dollars on a rifle that will only shoot a 4" group at 100 yds
