Well I noticed a whole bunch of "which is the best AR", "I'm building a AR what to use" threads. While I know there is much to debate on which brand is better then the other. I would like to know what part on the AR has the most effect on accuracy and reliability? Lower assembly, upper assembly, barrel? What would the great minds of THR.org say has the greatest affect on the overall performance of an AR-15, or perhaps a list of greatest to least effect.

IMO, the answer to your question is not a single note, but a chord.

Sorry if thats not the answer you were looking for.

Which is more important to you, accuracy or reliability?

Sorry, I'm a bit slow. I didn't quite catch your the meaning of your response, but to answer your question I suppose reliability.

I was trying to say that no single part is responsible for accuracy or reliability; its all about how many parts work together, like notes in a chord.

Hey there new fella, I was just trying to help. I hope my point was made...

If you want more clear answers, first tell us what you want to use the rifle for?

Are you plinking in the yard? Going to Camp Perry? Doing PSD work in Bahgdad?

If you can find one, buy a lower receiver from anyone but Vulcan/Hesse. After that, order a kit in whatever configuration you like from www.del-ton.com

I like chrome lined barrels on working guns, stainless heavy barrels on competition guns.

Good magazines are a must. They are impossible to find right now, but I really like Magpul Pmags. I also have a bunch of C Products mags.

A good trigger is important for accuracy. I use stock parts and send them to Bill at www.triggerwork.net He does great work fast.

Now was that really that hard??? Thank you for the knowledge, but I have to ask was it really that hard to cover all the bases like you did in your last post.

Now I know I could have been more clear on what I was going to use this for, but even without that information you were able to provide a ton of information for different situations.

It was posts like your last that I was looking for, as I said I'm a bit slow so all the information for as many situations is the best response. While yes this takes time did it take as much time for giving me music lesions? Once again thank you very much for a informitive post.

Just like any other rifle... its the Trigger. With out a good one, nothing else matters.

For accuracy, the barrel.

For reliability, the heart and soul of the AR-15 is the bolt carrier group. For serious use, you need a properly staked gas key, and a shot peened bolt. It's also helpful to have a full auto carrier, or at least one with a fully shrouded firing pin. If you've got a carbine gas system, a black extractor insert and 5 coil spring is a must. And an O-ring if the spring isn't all that strong. For middy and rifle gas systems, the stronger spring won't hurt a thing.

Best BCGs out there are Colt, BCM, and LMT. S&W uses LMT BCGs.

Oh, and with a carbine stock, you want an H or H2 buffer. A2 stock, the standard rifle buffer is fine.

#1 Trigger.
#2 The nut behind it.
#3 Ammo.

I haven't heard of a Match bolt for an AR and most barrels are more than the average person needs. Get a hand-me-down match barrel for pennies as a first upgrade, maybe?

I've shot out to 400 yards with a 14.5" at an Appleseed and landed everything on a 19" wide silouette. And, that's actually rather poor shooting compared to what's others are capable of.

It is the part that attaches to the stock, the shooter.

I would say this; if you don't get the right extractor parts, and a good staked gas key, all else is pointless. but if it were a single shot, because the above stuff busted, i would go with a good made bbl, 1/8 twist, chrome lined.

Staying legal? Forget that.

If you're going to stay legal, you best sell your AR right now, and get a lever-action.

Then, before that's banned, you better sell that and get yourself an Air-Rifle.

Then maybe a sling-shot for when they eventually take your pellet-gun away, as well.

Grow a pair, or sell your guns to someone who has some.

Oh, and magazines are the most important because they're the most prone to problems.

Without that magazine your fancy AR will only be a really accurate single-shot.

The most important part of any firearm is the nut that holds the trigger.

Alright people. Thank you for letting me know that I hold alot of the keys of accuracy and what have you, but I'm sorry C. Hathcock might even have trouble with a barrle that has had a file ramed through it. Also the shooter issue doesn't need to be brought up 5 times, one time is just fine. Lets keep try to keep it on the gun from now on.

I was thinking about ammunition; you need good ammo to be reliable, and good ammo to be accurate.

You need alot of ammo to be reliable and accurate :)

Proper lubrication of the rifle goes a long way for accuracy.

Good QC on your bolt group makes for a more reliable weapon.

The rifle is inherently accurate, the shooter may be the biggest variable.

Good magazines are a must.

Make sure you keep all files our of your barrel; clean carefully.

I think I'm going to need a drink after all this is over with. LoL Alright I think I got what I needed (in more ways than one), and I'll make sure to keep files away from my barrel.

Proper cleaning and lubing on a regular basis, paired with regularly changing out your magazines as needed. Many people have problems because they think that the magazine has an unlimited lifespan. It does not. If the magazine is worn out, buck up and buy a new one.

I would like to know what part on the AR has the most effect on accuracy and reliability?First up? Magazine. Secondly? Bolt carrier group - that includes the extractor and the bolt and cam pin and such things.

There is no "one most important part", since nothing will work without the other parts.

For most owners/shooters, a basic AR from a major maker will be perfectly fine and reliable. If you start thinking about using it heavily, or using it for real work (patrol usage for cops, warfare for contractors, defensive use for civvies, etc), you can eliminate most problems by getting a milspec bolt carrier group and using quality mags and ammo. Those are very simple, economical, drop-in upgrades, and get you most of the way to Colt/LMT/whatever performance.

for accuracy-the correct bullet size for your rifles rate of twist and the person behind the trigger.

reliability-combination of extractor upgrade, magazine follower, magazine spring, magazine and the person cleaning and lubing it.

and serviceable action spring and correct weight buffer.
