what's the benefits of having the M4 desinged barrel over just the 16" Hbar or 16" gov. profile? I ask because they're generally the same price or the M4 barrel is $5-$10 more. Assuming both can have feed ramps.
thanks.

+1 Like everyone said, it just have the mounting area for the M203 grenade launcher.
Usually it also have the M4 feedramps but some brands have it some don't.
The 16" HBAR and Gov't profile barrels also some brands have M4 feedramps and some don't.
My favorite type of 16" barrel is the LW profile, CAR gas system of my former pre-ban Lightweight Carbine.
I could carry it for a long period of time without getting too tired at the end of the day.
I have both 16" mid-length, mid-weight profile and M4 Gov't profile CAR barrels plus also a 20" A2 Gov't.
I'm planning to build a mid-length Gov't profile or a lightweight CAR barrel as a backup after I finish my current match upper project.

Does anyone know if the barrel of the Colt LE6721 is turned under the GH?
If so, that would be just right if in 1/7
