Re: PSA 20" A2 profile vs heavy SS
My rock river arms Predator Pursuit has a 20 inch stainless heavy barrel. Its the same one they use on their national match rifle. its heavy(er) than a basic government profile barrel but it is by no means a heavy rifle. If it were my money to spend, after I got the lower squared away, I would buy both a heavy barreled stainless upper and a gov profiled chrome lined upper. As far as accuracy difference, there is one. How much it matters depends on how you use your rifle. If you hang a 12 inch plate a 600 yards (a 2 minute target) and can't hit it with a scoped AR15 with a chrome lined 20 inch barrel, you won't hit it with anything else either. Now if you are trying to print a 4 inch group on that 12 inch plate, then the heavy stainless barrel is the way to go.
