How is the barrel length for the AR measured?
Or most importantly how does the BATF measure the barrel?
Unassembled?
Simply measure from the front of the collar that fits into the receiver to the muzzle?
Or to the front of a flash suppressor if permanently attached?
After assembly into the receiver?
The Barrel Nut and the Delta Ring will affect the measurement.
Rifles are traditionally measured assembled from the front of the muzzle to the front of the receiver. With the AR it is more difficult to get a measurement.
The reason I am asking is I am considering a carbine build using approximately 14.5" - 14.?" rifled barrel and a flash suppressor to get past the magical 16" to avoid a SBR. (Goal is 16.1" to keep the big bad wolf away).
