WTK- Ar-15 Barrel Question 16 or 18 inch

[Redbos99]

Going to have a upper built for me and am deciding about barrel length. I have 16 inch and 20 inch AR Uppers, but have been thinking about an 18 inch. Knowing the AR Guru's on this site someone must have some or have some great knowledge! Planning on having BUIS and a low powered 24mm or 30mm scope.

Thanks Much!

What are you going to do with it? Is your current 16" carbine gas length system, or mid-length. If its carbine length gas I'd go with 16" w/ Mid-length.

I am going to be doing a lot of plinking and want to shoot some steel out to 300-400 yards...... Upper would be on a Bushmaster lower( from a HBAR model from the late 90's) with two stage trigger and anti walk pins ( all from Bushmaster) Please let me know what you think!

Whats your price range?

I am a huge fan of BCM so would probably go with the Mk12 SPR w/ Larue 13" rail

If you're scoping it, and planning on using it at respectable distances (3-400 yards per your post), why wouldn't you want the extra velocity of a 20" bbl?

Why spend the money on something one doesn't need? Does it matter if the projectile gets there in .5 vs .6 seconds? Buying a barrel for better accuracy is one thing, increased velocity however, I don't understand.

The velocity will keep the round supersonic longer, which means it will stay accurate further, before it drops to sub sonic. Plus it will shoot flatter and have less wind drift

I would go with a 18" rifle gas system, short enough to move well, but long enough to be stable and shoot smooth

This is exactly the barrel I just bought from Remsport for an AR I'm putting together.

From what I've seen, most available is 16 or 20 inch, and 18 seems to be more expensive.

I'm interested. May I ask how much?

Maybe I misunderstood the post or I took the post too literally, but I thought he wanted to increase velocity not accuracy.

Please let me know how well that shoots. I am definately interested in one and wanted to hear some range reports.
