Chrome lining prevents your rifle from getting overheated during rapid fire and also does not pit as easy as a non chrome lining. I would pay the extra 40$

The overheating bit is a new one on me and I can't believe that a few microns of chrome will make any appreciable difference to the heat transfer rate. I am aware of the corrosion resistance and should I be using in situation when I could not give it the proper maintenance it deserved, I might consider it, however I'm not. Plus, my rifle is not semi-auto so there is no way I would be able to overheat it to that extent. My maximum rate of fire is probably never more than 30-50 rounds per minute.

There are also those who are of the opinion that chroming the bore detracts from accuracy & I'll buy that one.

My AR15 is used as a target weapon so for me, I do not believe that chroming the boer is an upgrade and therefore would not pay the extra $$

well in your case i would say so but overheating occurs more in un-chromed bores because there is more friction in a un-chromed bore and review from first grade friction creates heat.Now for the accuracy part it would affect it very little like 1 cms difference

Redbeernuts · 07-15-2008, 01:19 AM

Well, Your the pro Wunhunglo.

Said it before, everybody is entitled to their own opinion, even if they are wrong.

Actually I said this once when working in China and the guys asked"," What's an opinion?", when I explained, they told me that the "Party", told them what their opinions were!!

Getting a chrome lined barrel makes it easier to clean, true. Honestly though, unless you live in a jungle, theres not much of an advantage to having it. If you plan on cleaning your rifle after each trip to the range, and only put a few hundred rounds down it a year, your not gaining anything. On the bolt carrier group, personally I'd go with a LMT or BCM(Bravo Company) M16 group.

Jack75 · 07-15-2008, 08:02 AM

If you get a full auto what else do you have to buy so you canuse it or is it just full auto and no semi auto?

Pred · 07-15-2008, 08:14 AM

It's either full auto or not. Having an M16 bolt carrier group does NOT affect full auto/semi auto.

Jack75 · 07-15-2008, 08:18 AM

how come when you look at cmt bolt carriers it will say semi or full auto

Pred · 07-15-2008, 08:22 AM

Because you can order a semi auto group, or a full auto group. The only difference is the design of the carrier. The full auto is heavier. I've heard some people complain about the staking on the CMT bolt carrier groups. Now, the first AR I built I used a CMT M16 group and it's worked perfectly. For my latest build I use a Bravo Company M16 group.

Jack75 · 07-15-2008, 08:27 AM

Ooh.so would you recomend a chrome lined bore?

Pred · 07-15-2008, 08:29 AM

It all depends on what you want. You want a SHTF OMG the zombies are coming rifle, then yeah, I'd get a 1x7 twist chrome lined barrel. If your just wanting a plinker to put a few hundred rounds through a year, cleaning it each time you go, it really won't do anything for you.

Why a 1 in 7 twist for zombies? Is there a certain mandated bullet weight for Zombies??
I would have thought that at normal Zombie shooting ranges that virtually any barrel twist would do, as would any bullet weight???

Pred · 07-15-2008, 08:44 AM

Hmm.... well now. To answer your question, 1x7 allows you to use most any ammo you'll find in a SHTF situation. There is no guarantee a 1x9 twist barrel will stabilize bullets heavier then 62gr. 1x7 twist will however.

Jack75 · 07-15-2008, 08:46 AM

can you buy a .50 cal beowulf upper for an ar?

How stable does the bullet need to be at Zombie ranges (xxFeet???), surely an unstable bullet might be more efficient against them?

Jack75...........Yes, I believe so!

Jack75 · 07-15-2008, 08:50 AM

yesss it loooks like a really slow round though like throwin a lump of lead

Jack75 · 07-15-2008, 08:51 AM

it doesnt matter how accurate you are with zombies just hit them in the head with nething id just light them on fire

Uh huh... so exactly how are you going to hit a melon at 200 yards with an unstable bullet? In all honestly, all your posts are doing is giving Jack more to read that does nothing to help him out.

Jack75 · 07-15-2008, 10:13 AM

So what are your guys opinions about the century arms ar-15?
