While I will also be shooting mostly paper and varmints with the gun, I do want the tactical rail look. It's not exactly easy to figure out which ones are HBARs if the manufacturer isn't advertising it all over the place. However, something like the gun below is what I'm looking for.

That looks like a piston AR, so it may be ok. But if you're looking for a DI, you can't have one with that barrel on it.

Have you handled one with the four rail handguard?

The rails are NOT comfortable to hold.

That looks like a Colt LE6940 and it's NOT an HBAR.

Actually the one pictured is GI. The pColt LE6940P (piston gun) will have the gas piston takedown ring on the front of the front sight base (gas block).

Rail covers are standard with the Colt LE6940 and make a big difference in comfort.

more than AR6721?

I thought Colt only made the AR6721 as their current HBAR AR-15 rifle. What are the other HBAR model numbers?

The socom is not an HBAR: it's heavier than a standard barrel but lighter than an HBAR. If the smallest diameter measurement on the socom is at least .75", then it is an HBAR. To the best of my knowledge, though not absolutely certain, the barrel tapers thinner than .75" under the handguard.

I always thought all SOCOM barrels have the .203 cut.

6920 SOCOM is def NOT an HBAR.

Should be fine then, as long as the barrel ain't necked down anywhere.

Doobie · Feb 16, 2015

I'm confused now too because the barrel is "necked down" at the '203 cut...or does that not matter as long as the barrel isn't under a specified diameter?

Lou45 · Feb 16, 2015

As the accepted standard (there's no definitive standard) so long as the barrel diameter measures at least .75" at it's thinnest point, it would be good to go. I'm not sure the 203 cut will measure up though.

SOCOM barrels definitely have m203 cuts which is what I thought disqualifies them.

It doesn't matter if if it's necked down (or what any of the measurements are) if the manufacturer describes it as "heavy barreled" in literature. Buyer just needs to keep a copy of that literature, in case it ever becomes an issue.

Perhaps.

But if anything were to become an issue, it's a hell of lot easier to convince the law that a barrel that maintains it's size all the way out is a legal one.
