Archived [ARCHIVED THREAD] - Firing Pin Protrusion for AR10 / 380 / 7.62 X 51, is it the same as AR-15?
Posted: 3/9/2021 7:58:14 PM EDT
What is max / min for  AR10 / 380 / 7.62 X 51?

I know what it is for AR-15, I can find that everywhere.

Google not working for me today for some reason.

Firing pin protrusions are different.

A small rifle primer and a large rifle primer call different firing pin protrusions.

AR15 5.56 firing pin protrusion = 0.028" - 0.036"

AR10 308 firing pin protrusion = 0.044" - 0.060" (0.055" - 0.060" preferred)

Random samples of two AR10's.

AR10 #1 = 0.052"

AR10 #2 = 0.058"

Both are far greater than 5.56 AR15 protrusion specs.
