AR barrels
What's with the necked down portion in the middle of the barrel?

Re: AR barrels
You're referring to the stepped portion in front of the front sight post?
 It's there to accommodate the mounting of an M203 grenade launcher.

Re: AR barrels
We couldn't make a grenade launcher without doing that?
Seems like a point of failure.  Glad mine are Hbars.

Re: AR barrels
I believe on the full 20 inch versions, that step is under the handguard, so it is never seen.

Re: AR barrels
I would be more concerned with the trigger, it does not reset all the time and the firing pin remains out. The rounds go off when loading them.
