I'm looking to replace the hbar on my AR (5.56) with something lighter. I see there are a few options. Any recommendations? I'd like to keep it under $300 but of course quality is key. I'd like chrome lined... not chrome moly.

Even some love for thread jackers tonight! http://www.model1sales.com/item-detail.cfm?ID=BSC20E&storeid=1&image=bar20.gif&CFID=61721490&CFTOKEN=83291833
Just change the barrel options in the drop-down window. $235 for Stainless Threaded

I have NO experience with this vendor or these barrels. But I can search like a hungry dog.:p

Thanks! That looks like a good deal. Now I just have to figure out what the consequences of going from a 1:9 twist to a 1:7 will be.

Forrest,

Then you want a std 20" M16 "USGI Profile" barrel. It's tapered under the handguards.

You can get these from various vendors - you might find some Colt around, Bushmaster has done a run of these, etc. CMMG has 'em too, Armalite, and perhaps Yankee Hill. BravoCoUSA may offer 20" USGI chromed bbls too.

1/7" twist is best if you'd like to shoot the heavies (72-77gr gr). The Armalites and Bushmasters are 1/9" twist.

Also (recommended): CMMG has an unusual profile called the 20" "Medcon". It begins reducing tape *forward* to a thinner profile as you move down the barrel. You may find this bbl to be a bit stiffer/more accurate than a thinner USGI profie under the handguards, yet way lighter under an HBAR profile.

Weight is not the only thing, a bit of balance helps.

Stay away from Model1 Sales - non-chrome lined. Stick with the vendors I've listed.

Whose barrel do you have, what twist is it, is it chrome-lined, and are you selling it?

While those vendors are fine, but Model 1 does offer chrome-lined barrels but not the one I linked to...
And Mr. Wiese knows his stuff.

I'd stick with 1/9 twist unless you know you'll be shooting 400+. I've seen a bunch of frustrated guys trying to get their new 1/7 twist rifles to shoot MOA with anything other than 70+ grain-weights. YMMV, of course.

I've used various 1/7" twist bbls - Colt, Noveske, CMMG - to shoot quality 55gr and 69gr quite nicely.

Methinks any problems with way-beyond-MOA shooting w/ 1-7" twist bbls may not be with the twist, but the bbl mfgr, ammo, or shooter.

Hi Bill! Thanks for the reply. BTW, I've been telling Ben we need to go get some more steak with you again soon.

Currently I have an Armalite 1:9 20" hbar that was shortened to ~18" and had its muzzle threaded. It is chrome lined. I would certainly be willing to sell it if I could locate a suitable lightweight replacement. I like Armalite so I think I'll start with them first.

Again, thanks for the info. I'd much rather go with one of the known brands than this Model 1 Sales outfit. I wouldn't ever skimp on a barrel.

Sweet thanks! Didn't mean to hijack but since the topic was barrels.
