Ill be swapping out my a2 16" uppers for a 14.5 pinned or 16" barrel with a lighter profile? How sturdy are lightweight profile barrels and will it reduce a significant amount of weight? If not sturdy what profile do you recommend?

Bump as I was going to ask about the same question.

The lightweight profile is plenty durable unless you are using it as a pry bar, possibly. Personally I prefer a profile that is lightweight or tapered, not the government profile.

My son recently built his first AR using a lightweight 16" barrel from AR Performance.  The drop in barrel weighs 1 lb 9 oz, the completed rifle weighs 6 lbs 6 oz.  Wilson Combat makes a similar barrel in SS.  If you want a lightweight AR, with a 16" barrel so you can change muzzle devices at will, look for a barrel that weighs less than 2 lbs. - CW

If you go 14.5" go LW for sure but If your gonna rock the 16" I'd do a M4 profile.  I hate the government profile barrels yet others love them......

I like the gov profile just because its the same size from gas block to flash hider and I don't have a 40mm launcher.

LW in my opinion looks weird because it slims down after the FH and to me looks toyey.

But I was assured (by DD) that a LW can stand anything the others can except for being the aforementioned prybar.

What about POI impact shift with a LW barrel?

I'm free-floating anything I do, but shooting a LW from cold to hot while slung or with the barrel braced on a bag might show some differences as it heats. No?
