Hey folks. I am about to build another rifle and am wondering about "real world" difference in velocity between the 18" (Middy gas) and the 20" (rifle gas) length barrels.
I know it depends on what I want the rifle to do etc, etc.......BUT has anyone had the opportunity to chrono these? I guess it's a difficult question because of all the variables involved. I don't need an exact to the f.p.s. answer.
I guess my real question is: "Will the 18" barrel be combat effective at 800 meters?" I have to think that it will be looking at the ballistic data on AA's site. I am just wondering if the extra 2" is worth the weight and length I guess. Any insight is greatly appreciated.
