DPMS 308. VS AR10 ARMALITE

[PR0230]

IVE READ ABOUT THE TWO BEING DIFFERENT.... THAT YOU CANT MIX AND MATCH....
WITH ARS THERE ARE BARREL EXTENSIONS, CARRIERS, AND BOLTS..... EACH SPECIFIC TO THE
DPMS OR AR10 TYPE....

I HAVE A SAVAGE MSR10 IN 308.... THE UPPER HAS THE STRAIGHT DIAGONAL LINE TO COUPLE WITH THE
LOWER. NOT ROUNDED.... THIS IS ARMALITE. AND THE FIRING PIN IS AN ARMALITE DESING WITH A SPRING... SO I BELIEVE
THE TO BE ARMALITE IN DESIGN...

Im HAVING A COMPANY MAKE ME TWO BARRELS, AND ORDERED TWO BOLTS.... AT THE TIME I HAD THEM MADE I DID NOT
SPECIFY ANYTHING SPECIFIC TO TYPE CAUSE I DID NOT KNOW.... AND IM NOT SURE WHAT IS BEING USED FOR THE BUILDS...

IF THE BARRELS I ORDERED WERE MADE WITH DPMS EXTENSIONS, AND I TRIED TO USE MY ORIGINAL BOLT,
SO DPMS EXTENSION, WITH AN ARMALITE BOLT, WOULD TESTING THE TWO WITH NO-GO GUAGES DETECT THAT
THEY ARE INCOMPATIBLE?

WHAT ARE THE DISTINGUISHING MEASUREMENT OR CHARACTERISTICS OF A DPMS / AR10 EXTENSION OR BOLT?

I have an armalite super sass that shoot honest sub .75 if i do my part with FGMM 168gn(it has the LMT BCG which is Dpms pattern)
Then i had decided to build another uppers so i went with a dpms pattern Krieger barrel+ armalite upper+armalite BCG and it pass the Go and No Go gauge test with flying colors.

So i bbelieve that the safest route is to always gauge your combination prior shooting it.

I would ask Savage if there bolts are armalite or dpms pattern. Once you determin this, you should be good to go. Just ensure that it Head spaces before firing

this thread seems to indicate DPMS bolt and extensions

I think the difference is the barrel extension is how they thread into the receiver (link is 3 years old). But you are correct, nothing in the 308AR world is standard. Some things are close but Armalite and DPMS are definitly completely different. You will need a compatible bolt to go with your barrel.
