This is probably an A1 profile barrel.

Palmetto has an interesting Ultra Light Weight barrel: https://palmettostatearmory.com/psa-...ng-handle.html

Their lightweight barrels like this https://palmettostatearmory.com/psa-...ed-welded.html or this https://palmettostatearmory.com/psa-...-7-barrel.html do not actually look lightweight and more of a medium weight vs other brands.

Spikes 14.5" CHF barrel is also very lightweight: https://www.spikestactical.com/colle...htweight-14-5/ and is probably comparable to BCM's ELW.
