HPT is a destructive test for non MIL-SPEC parts like barrel and bolt! After HPT comes MPI, which decides if the part met the spec, or was destroyed/didn't meet spec! If a company proof tests, they should also MPI according to MIL-STD-1949(a huge document outlining ALL the details of HPT/MPI testing). There are also other specs, and drawings that need to be referred to for EVERY part in the weapon system as to whether they meet spec or not. Moral of the story, HPT/proof testing is destructive to non-spec parts! Ok I lied again and was back...but, buy what you want, I will no longer offer advice, nor opinion on this subject, as there are many more eggsperts out there who've never even seen the actual MIL-SPEC for this particular family of weapon system.(even though it's available online). Hell, I'd go out on a limb and say most INGO builders don't know what the 23&P is?
That is not destructive testing. Again by definition in destructive testing the test part is destroyed. It literally means testing to destruction. Here are some examples. Destructive testing for pressure vessels may include pressurizing until rupture, or for cars how many hrs straight the engine can run before failure, or for rifles how many rounds it can fire before breakage, or shear strength for metal alloys. What you described is pass/fail testing.
