lord, i hate it when people call anything but the actions of a trained sniper sniping. please dont do that again.

what you will be doing is long range varmint hunting.
 
It is this simple. If you want an AR that you intend to use for the defense of your life then you need a chrome bore.

If your AR is only going to be used for punching holes in paper or hunting varmits then you can do without it.
 
Good thing I found this thread. The AR that I'm saving for will be utilized for varmint sniping, therefore, it's bore will be... I still can't decide.

I know a guy who uses his issued M16A1 (issued by a PD, not uncle sugar, and the funswitch was removed) for whacking P-dogs at great distance. The varmits don't seem to know that they should not feel threatened by a chrome lined bore. Actually, they don't feel much of anything after they s'plode.

Just buy one. They both work. CL really shines when you can't clean the gun regularly or you're firing FA, but it's not a bad idea on a semi. It won't make much difference unless you are making a real precision rig. If it costs more, don't get it. If you get a good deal on one with it, buy without hesitation. You can spend hours agonizing over something that won't make one whit of difference. :)

And, just to make things more confusing, my HD AR is non-chromed. I'll let you know when I have a malfunction that a chromed chamber could have prevented.

PS Don't hold your breath. ;)
 
And, just to make things even more confusing...

Both my AR and my AK have chrome lined barrels, but now that SEI offers M80HT, only one of my modernized M14s has a chrome lined barrel.

M80HT is a surface hardening process that SEI uses to give a 60 Rockwell case hardness to a depth of about .002 to .003 - resulting in a
corrosion resistant and almost wear proof finish without negatively effecting accuracy like some chrome linings do. Cryo is also available.


I don't know if this service is available for chrome-moly AR barrels, but I don't see why it wouldn't be.
 
Get the chrome-lined if you aren't looking to compete or do other long-range shooting such as varminting where every bit of accuracy can help. It's a nice feature that adds to the durability of your gun.
 
Amortized over the useful life of the bbl. the cost of chrome lining is negligible.
Having it doesn't make one a mall ninja.
Eschewing it doesn't make one a grittily realistic pragmatist.
Before there was an internet, I'm pretty sure I wasn't this retarded.
 
I like chrome lining because it matches my wall-climbing ninja boots the same way every class A master marksman on this board likes non-chrome lining because of their inherent ability to shoot 0.223" groups at 400 yards with their bushmasters.

I mean, seriously...

$40 with the benefit of longer life (something you don't need) and resilience to crappy ammo (something you wouldn't feed your gun if you liked it) at the cost of a miniscule amount of accuracy (that 99% of shooters can't notice)? Yea. personally, I'll take the chrome for the sake of not having to treat my gun like how a gynecologist treats a virgin.
 
I definitely recommend chrome lining for it's greater reliability, longevity, ease of cleaning, rust resistance, etc...

I definitely do not recommend Model 1. Never seen anyone walk away from them with a good experience, personally...
 
Chrome-lining is

1: bad for accuracy

2: good for full auto weapons where heat dissipation is important

3: easier to clean, for weapons that see hundreds of rounds at a time, almost daily

Yes, I suppose that's why the FN SPR A3 G with it's chrome lined bore holds sub 1/2 MOA accuracy for 10K rounds. That's also why all FN SPRs, all with chromed bores, are guaranteed to shoot MOA or better with premium ammo.

Chrome lining does not an inaccurate barrel make. Poor chrome lining does an inaccurate barrel make. Proper chrome lining does an accurate, durable, and expensive barrel make.
 
Just go stainless and enjoy the blank looks from people who wanted to argue this question. Especially since the option for stainless usually costs the same as the chromed lining.

Question: If you order the option for a chrome-lined barrel, does that include (by default) the chamber, or would the chamber be under the "chrome plated bolt" option? And, what would be the benefits of having a chromed bolt but not barrel, or chromed barrel but not bolt, for someone without the "fun switch" in their lowers?

Chrome resists corrosion and offers a hard, smooth, low-friction surface that can help case extraction (especially when the gun is dirty or when people like me use lots of Wolf ammo), ease cleaning, and extend barrel life (to what extent I have no idea). In full-auto (and to a lesser extent in semi-auto) guns, the lower barrel friction helps reduce heat build up in the barrel. It has nothing to do with heat dissipation, only in reducing the production of heat in the first place. According to gun designer Jim Sullivan, it is friction, not the heat from powder combustion, that is the main contributor to barrel heat. Stainless is rust resistant, but, unless lapped, does not offer the other advantages.

I am not sure I understand your first question. A chamber is part of the barrel and a bolt is a bolt. They are two separate parts. The M16 used to have a chromed bolt, but hasn't since the late 1960s. The chromed bolt was easier to clean, but also suffered from hydrogen embrittlement. Basically, it just wasn't worthwhile to chrome plate it. The current M16, like good semi-auto clones, does have chrome-plated surfaces on the bolt carrier and gas key, which reduce friction, rust and wear and make cleaning easier.

You can buy a chrome plated bolt nowadays, but I don't really think it's worth it. Everybody's got their limits as to what their willing to pay for.
