About to build a 330 Whisper

[daveosok]

I am also doing an AR15 for my buddy. I already cut the threads and fitted the barrel extension and bolt head play .003 and torqued it down. Contoured the barrel and cut the crown, threaded the muzzle and are going to drill the gas hole .0625.

Gonna make the gas block .750 barrel is .7495 and hes putting an adjustable gas tube on it. After the barrel block section it jumps up to .9125 for 8 inches or so. Its 17.5 inches long.

Yep Ill get some pics on here sometime in the near future.

Thanks for the help. I have a Stoney Point OAL gage that ill use to set the bullet length for magazine length and then throat until dummy rounds fits snuggly after cutting the chamber to proper headspace gage dimensions.
