All dimensions listed will remain the same regardless of barrel length. For prefits or contoured blanks, the only aspect of a contour that changes with barrel length variations will be the length between C and E (or A and E for straight tapers). Also, the angle of the contour taper (if any) from C to E (or A and E) will change depending on barrel length.
The muzzle diameter (E) is measured on a contoured barrel or blank and does not account for any muzzle threading. Threading a muzzle will cut a shoulder (typically) .625" back from the normal muzzle end and that shoulder (at the end of the threading) will be a slightly larger diameter than what is measured at E (except for on contour #12). Take this into account when selecting a contour that will have a threaded muzzle.

In some instances, the gas block journal length (D) will be 1" long on contours where it would otherwise normally be 1.92" long.
This can be due to overall barrel length, as typically extremely short barrels will have the 1" long GB journal instead of the 1.92".
Some AR Barrel contours, notably the spaghetti and lightweight, will have a step near the muzzle (on threaded barrels) to increase diameter slightly to maintain enough of a contact surface for a muzzle device.

Due to overwhelming call volume, we will not be performing order status checks on any orders still within their estimated lead-times. We will perform status checks on those at the end of or after the estimated lead-times. Email requests are faster as we're able to address them sooner than the phones.
Also due to overwhelming call volume, voice messages left with our Customer Support number may take quite some time to get a response. Our phone system sometimes overwrites voice messages left by customers so please either try again or send a message to sales@x-caliber.net (as this email address can be checked and responded to anywhere by anyone here), you're far more likely to get a prompt response with an email inquiry than via phones for the time being.
Before placing an order, please double-check to ensure all details are correct beforehand! Delays involving order change requests continue to increase.
