Can someone supply me with a good quality image of muzzle threads on an modern .50 cal M2A1 barrel?
A close up of the threads with a scale next to them showing overall length would be great. Also the shoulder and crown portions.
I need to get an idea of the thread relief. I appreciate any assistance
Thank you!

Depends on which FH you want to use. Some are LH threads, some are RH threads.

Here is the RH tread. http://www.smithenterprise.com/spec/Vortex_0.50_cal_M2E2.pdf
