I have a titanium YHM 5.56 suppressor and am thinking about getting a 16" lightweight AR barrel to use it with(only barrel in stock anywhere). It's not a pencil barrel but it is lightweight. I'll link the barrel below. The suppressor only weighs 12 ounces but I'm not sure if that is enough to cause any change in performance with a light barrel. Anyone have experience with this?

Barrel in question:
Del-Ton, Inc. AR-15 16" Pre-Ban Barrel
 
I run a AAC 7.62SD on my 16" AR(Very similar contour if not the same) with absolutely no problems. That was after about 2-3 mag dumps. Still shot normal groupings of 2-3in groups with an Aimpoint.

How do suppressors affect accuracy? I shot with both a TL Guns smidget and an AAC M4-1000 QD can on this course. Standard issue DPMS M4 16" barrel upper. Worked out just fine.

Adding weight to the end of the barrel(or any kind of pressure) will cause a change in the barrel harmonics. From what I understand a heavier barrel would be less susceptible to this as it is more ridged.

Don't think you understood my post. I embedded a link to a post on another board about shooting a 16" carbine out to 700+ yards, accurately, repeatedly, with a suppressor.

Worked just fine for me. I understand barrel harmonics, one of the things is that ALL barrels have some degree of whip and barrel bores aren't axially parallel (meaning they're more like a wormhole) but that's why we do OCW and match bullet weight to twist and all that to find the most accurate load for a particular gun.

I use suppressors on all my bolt guns and most all my AR platforms and don't have a problem with them.

I am specifically addressing PENCIL(thin contour) barrels with this thread. I didn't see anything in regards to lightweight barrels in that other thread. I have personally experienced noticeable accuracy changes using lighter contour barrels with heavier suppressors on other setups. The point of this thread was to get feedback from people who have used light barrels(not M4 or M16 barrels) in conjunction with a titanium suppressor.

I have the AR built and zero'd in irons/function tested it. Will probably throw a scope on it and test accuracy with my can at some point.
