I see Bushmaster is offering a 20in stainless barreled upper it's 1x9 twist.So what's the advantage of this barrel over their 20 chrome-lined barrel.For years bushmaster has been saying that chrome-lined barrels are superior to stainless.Don't get me wrong it looks nice and I may even get one.I guess ther was a big customer request for this.
A stainless barrel is more accurate. Most longrange competition AR's use stainless barrels for that extra bit of accuracy. However, its not as easy to maintain and clean as chrome. I think chrome lasts longer too. For the adverage shooter, chrome is the best choice.
i think they are trying to appeal to people getting started in highpower shooting, & looking for a bit more accuracy than a chrome bore...but still keeping the price lower than most competition/dcm uppers. (bushy, cle, etc.) pat
