ar 15

[lytur9]

Planning to buy an AR15,. would like to know what lenght barrel to get that will be accurate at 400 to 500 yards

 

[Nomad.2nd]

20 inches.

USMC Qual out to 500...


I'm no exceptional shooter, but given 2 days of prep (Saposto get a week of 'range week' but sometimes it doesn't happen) to get used to the pecularities of the particular rifle...

I'll give 8-9 hits outa 10 on the target at 500.

(M16, Military ammo)

Have tried with an M4.... It's embarasing...

(Although in the Gunsite 223 class I used an M4 with a Tridjacon Reflex site to hit peper popers unknown distance out to 400... But I'll admit I was at the top of my game (Training wise) at that time)

16" is a good length. Some would say something a little longer might be good, but that depends on a lot of factors. If you are concerned with accuracy, barrel type is more important than length. For example, a good stainless or chrome moly is going to be a bit more accurate than a chrome lined, but most feel chrome lined is good enough for government work, and it is arguably easier to clean and takes a bit more of a beating.

+, The longer the barrel (Gas tube) the more reliable the weapon.

What weight bullet do you intend to shoot? Up to 62gr, you should be OK with a 1 in 9" twist barrel. Heavier than 62gr, I'd opt for a 1 in 8" twist barrel.

 

[lytur9]

I really never thought about what type ammo. This will be my first AR and I need all the help I can get. THANKS

I say get at least a 1:8 twist. That will give you some of the best range of bullet weight. My 20 inch 1:8 twist will get .5 or better moa with 55grain all the way up to the heavy stuff.
