| Still learning this posting stuff....like I said in my first post..(great fast responses)...."new ar build"....I have a real good lower with a pretty light trigger setup and now I'm looking to buy a already built upper. My questions are ...chrome lined barrel?... Carbine length or mid length ?......I'm looking for it to be very accurate at long range ....but also know I only want a 16 inch barrel.....Also ....1-9 twist compared to 1-7 ...my friend said just because of cost and avail or rounds that 1-9 is best for 55 gr 223/5.56... ..any help with these questions or how to work this forum / postings/ topics |

get a SS 1/8 with Wylde chamber, like a Lilja, if you want accurate, not chrome lined. length of gas tube is really irrelevant, just get whatever comes with the barrel that meets your primary needs. a Lilja is carbine gas and a noveske recon is mid.
edit. 55 is not ideal for accurate long range shooting. |
| What ever is both more avail and cheapest mainly but also want the option of being able to be very accurate at long range....if that means spending extra for higher gr bullets that's fine.....I will primarily be shooting either at range or coyote....but may someday have to be sniper like... |

If your gonna mainly be shooting standard 55 62 grain blaster ammo this will do

I respectfully disagree regarding the chrome lined barrel recommendation. Melonite (hot salt bath nitride treatment) or the other various trade names for the process, results in surface hardness superior to chrome. Nor is it a plating of a barrel cut undersize to allow for what may be a surface plating that is not uniform. Rather, it is a hardning of the actual steel at the molrcular level, leaving the original rifling crisp, sharp and in original unaltered shape. This increases accuracy potential. Further, the nitride treatment is to the whole barrel and barrel extension, and not just the bore and chamber. Accordingly, the exterior of the barrel is also harder and more resistant to scratching and corrision.
Such barrels typically cost no more than chrome lined, and often less. Nor do you need a Wylde chamber. Just get a 5.56 NATO chambered 1:9 or 1:8 melonite carbine barreled upper and start shooting 1 MOA groups with widely available 55-69 grain ammo. Spikes Tactical makes some like that in the $600 range from various vendors. |

So, you want your AR to shoot cheap/light ammo, expensive/heavy ammo, be "very accurate" at "long range" with both, shoot at the range, shoot at coyotes, and "be sniper like".......oh, and you want to do this all for $600.00 or less. No offense, but I'm getting the idea you have no clue about ARs, no clue about their limitations, no clue about what you want one to do, no clue about what you really mean by "very accurate", "long range", or "be sniper like", and you live in some fantasy "SHTF" world of make-believe. Maybe you ought to consider having a real heart-to-heart with yourself about what you really want from a firearm, and then start from there. Right now, you're waaaaay out there. |

This would be a good barrel for you when they are back in stock.

The old method of chroming which started with barrels machined to oversize ID's and then chroming them ( hopefully ) back to size is obsolete and has not been used for rifle purposes in decades.
The modern method is a a precisely controlled and highly repeatable precision electro chemical process known as minimal etch chroming. It is the process done by a few companies (US Chrome is one ) that specialize in it and do it for Colt, FN and others manufacturers. First they require the barrels interior to be be on size. They remove 1 ten thou ( 1/10,000th) of an inch through the polishing, honing and etch through the bore and replace it with hard chrome. They hone and polish the chamber 2 ten thou of an inch and apply chrome in the same amount. When all is said and done you are left with a far more accurate barrel than the old method of supplying barrels with large ID's and chroming them to size. IMHO Melonite is most likely is the wave of the future in barrels but traditions die hard so chrome will be around for a long time to come. |
