Bolt ramp job.

AR/M4 AR Pistols & Pistol Caliber ARs

I received my RRA 9mm upper with ramped bolt from ADCO. It works just fine with a RRA 2 stage FCG, with a CMT notched hammer and with a DPMS un-notched hammer.

I have read in TOS that MGP is the man for the ramp job. Whats the difference between his job vs ADCO’s?

Anyone here have a pic of a RRA UNRAMPED bolt. This is my first time with 9mm AR and havent seen an unramped one. I have curiosity as how much metal was removed from the bolt.

My ramped bolt would not run with a notched hammer…

I’d go with Steve. He isn’t the one who did mine though.
