I would like your thoughts on AR barrels. I am trying to build an AR for home defense and range toy will not be doing any kind of competition shooting. I am planing on adding a slide fire stock. The reason I mention the slide fire is there will be time when I fire a lot of rounds down range very fast and I know that has to be harder on a barrel. So I am taking that into account when trying to figure out what barrel I want/need.
What is better as far as twist on a 16" barrel 1/7,1/8 or 1/9 I see more 1/7 available. I know the different twists work better with different grain bullets. I don't what grain bullets I will be using, probably what ever I can find. Most barrels I see are made of chrome molybdenum"chrome moly" or chrome vanadium. Chrome vanadium is supposed to be the new mil spec for the us military is there really a noticeable difference? Whats your thoughts on chrome lined, I know that some say that they may slightly decrease accuracy and they are more forgiving on cleaning and harsh environment. Some say they last a lot longer. Do you think the C.L really last longer, would you spend the extra money? What are your thoughts on a stainless steel barrel? How does S.S compare to a barrel made of chrome molybdenum or chrome vanadium with out chrome lining? Would you get a S.S barrel before the others? Any thoughts would be great. |

If you are planning on lots of rapid fire, I would go with an HBAR as that will take longer to heat up. It will take longer to cool off as well though. You want at least a chrome lined bore of 4150 steel, but you may want to go with a 4150 nitrated barrel. As for rifling twist, not sure how the different twists would effect longevity. I generally prefer 1/9 as I mostly shoot 55 gn, occasionally 62 gn. And 1/9 works fine with my ciener .22 kit.
Good luck. |
