A bit pricey but if real accuracy is a must JPRifles has both medium/light 18" rifle gas barrels. I picked up the light weight and it is a tack driver (1/2 MOA with premium ammo) at 100 yds. It also came with their enhanced bolt which was a nice plus.

rugerdawg, the Nordic barrels are made on the same machinery as the JP barrels...just cost a little less and have a few improvements...

AR Performance usually carries an 18" rifle gas as a 3 gun barrel but they are out of stock at the current time.

Rugerdawg, thanks for the suggestion, but those barrels are just to expensive for my budget.

Metal God, you may not see those pics in a while. I'm putting it together on college budget. It's gonna take a while. Thanks for the support though.

"Mil-Spec" worshippers are probably the largest reason you don't see rifle gas on 18". 18" barrels are not common in the Military, but they are likely the best all-around version. The main reason they are even out there is because the 3Gunners kept screaming for them. I've run several Monte Carlo analysis models and with rifle gas, 18.5" is about optimum when all the parameters are considered.

What size gassport did you find worked best with the 18.5" barrel?

If memory serves me, Crane specs a .104 port on the mk12.

I'm running a .96 port on a HBAR mk12 clone, 18" barrel, with rifle buffer. It's reliable and soft recoiling.

I did purchase a 16" nordic barrel a few years back. I believe Lilja was making them for Nordic at that time and it was a great barrel. I have not tried the newer Nordic barrels but am seriously thinking about the 18" Nordic as its reviews really seem encouraging.

FordV8, how does that .96 port cycle low powered .223, like pmc bronze, or russian steel cased ammo?

I've had no troubles with any ammo yet. Including PMC, a few NATO milsurps, some UMC, American Eagle, some Ultramax, and a few boxes each of Silver and Brown Bear.

Though, I mostly shoot Hornady and Federal.

Round count is only around 400. I'll begin to trust her at 1000!

I have one of these BCM uppers. Rcoil is minimal een with the A2 birdcage. No complaints other than the handguard makes it heavier in the front than I would like. (Mine has a Midwest Industries one piece SS free float rail)

The Daniel Defense 18 in S2W bbl is in your price range.Hammer forged,chrome lined.I'll trust mine to give a 3 shot group you can cover with a quarter.(I know,that will bellyache some folks.It works for me)

Another barrel in your price range would be a White Oak.They offer SPR barrels.I have not tried one,but I'd spend my money on one.
