HPT and MPI testing. Why?

[lysander]

HPT absolutely shortens the life of the bolt, and this was explicitly covered in a NDIA briefing.

What it does get you is assurance it will work out of the box, at the cost longevity. Probably a good idea if you want to be able to spit out a TDP to any vendor and have confidence in a QA/QC process.

You will see bolts for GPF contracts maintain the legacy HP/MPI and some to other units not specify this.

Which NDIA Brief?
