Armalite Technical Specification question
4/16/2011 4:39:52 PM
Hey TR,
Was reading through the specs tacked above and had a question.
You list bolt carrier specs as:
"•AR-10 bolt carriers use 8620 steel - M-15 bolt carriers use Carpenter 158 steel. "
Are you saying the M15 bolt carrier uses Carpenter 158,or is this reference to the spec'd material used for the bolt?
TIA

I had some incomplete info on this. Below is the corrected spec info. I changed it as well in the tech spec information on this website.
•AR-10 bolts and carriers use 8620 steel
•M-15 bolts use 158 Carpenter steel and carriers use 8620 steel.

TR,
Is the Carpenter 158 steel for the M15 bolts a recent change?
It was my understanding Armalite used 8620 for the M15 bolt material as well....per website and previous conversations.

Reference to the 8620 steel for M15 bolts rather than spec'd Carpenter 158 is what has caused me to not use Armalite M15 bolts in the past.
This is good to know.

The info from the website is incorrect. The information for the 158 Carpenter steel for the M-15 bolt was something I wasn't aware of so I assume this is nothing new we started doing. Sometimes information doesn't always flow down to us from engineering.

I was told that their bolts were 8620 as well. Very good to to see this new info.

Hey TR,
Thanks for the response.
I know it may seem pretty silly to some,but the devil is in the details..... and the Carpenter 158 spec'd bolt steel is important.
Certainly dictates what I buy when looking for a bolt.
Does Armalite HPT/MPI the bolts?

We don't do any High Pressure or Mag Particle testing on the bolt. We have them Shot Peened on the surface finish which is done at high speed to relieve the tensile stresses in the material after machining. We have done Mag Particle testing in the Engineering Department but not on production runs.
