Stoner barrels are not sourced from Shaw.
The Grendel chamber is a SAAMI standard as is the ammunition. There will be some variability depending upon the reamer wear, but it is inside the tolerance envelope.
Manson usually has HSS reamers and for a project like this a solid pilot could be used. Unless you want to strip the upper you will need an extension handle. If the head space is correct use a stop reamer.
