I've used F and Cage Code.  Just depends on what the armorer had in the system.

Ever come across any TC 1B1B6 stamped carriers with F stamped bolts?

Sure looks like it.

I have 2 that I bought maybe 7 years ago. TC CAGE on carrier/MPF marked bolts.

Come to think of it, they may have come from TBA. Can't remember .

Normally don't look at the BCG markings during maintenance.  However, I do have 1B1B6 is spare parts and have seen them occasionally in the past.  Almost all my bolts are either Colt or FN.  So yes to your question.

Thank you for the info. Any idea when the cage code carriers came into existence?

Looks like 2001-2011 for DoD contract info.


ETA: And I believe that is for carriers only, no bolts.


Every one that I've seen has had an FN bolt in it.

Good to know. Any idea where the F marked carriers/bcgs fall in as far as time frames?

MPF bolt heads have been used in M4s since at least 1999, maybe even earlier.

1998 FN secured their first DoD contract for M16A2s.

CD could tell you more than I regarding those specifics.

Gotcha. I’m mainly looking at the time frame of the Mueller stuff being used which I believe started somewhere in the mid 2010s.

You did a typo.  FNs first contract for M16A2s were in 1988.  In 1990 we equipped the New Kuwaiti Army with them.  I remember looking at near new FN M16A2s in early Mar 91' right after the seize fire went into effect.  I was in Kuwait City with 5th SFGA.

@Combat_Diver
Safe to say FN bcg and bolts a long with 1b1b6 were being used with Mueller receivers and such?

Yes, Only when guns are first issued from Colt or FN.  After that every part except lower (lowers too but rarely) get replaced as they are wear items.  Any Governmental parts supplier can be found into or on any variation of M16/M4.

You ever see an original M1 Carbine?  Remember Underwood produced the most parts (35) and that was about 70%.  Rest of the gun was from other suppliers.
