Thread: AR parts Makers Marks?

i bought a bolt group at the gun show last year i forgot to to ask him who made it. i fully inspected it and it looks great the only thing i had to do was stake the carrier key every thin else was good.

any way does anyone recognize this makers mark?


It is a circle with a Y inside.

isnt that a peace symbol?

no, it i thought it was at first but the intersection is not centered.

Maybe Young Mfg.... Not sure - If noone around here knows I'm sure someone on the AR15 dot com tech forums would know...

young are marked Y/M with a hexagon around them

No clue then, sorry...

I'm certain you know this...and I don't mean to be stepping into your business but as a suggestion since you're mixing parts (expecially from an unknown source) do you have the capacity to check headspace? If not, then you might want someone who can - do so. Who knows how that bolt will match up with your rifle's upper.

Something to consider anyway...

yeah i did very carefully check head space.

i did my home work before i started building. I just cant remember who the manufacturer is.

my carbine only has 140 rnds through it but have not had a single issue yet. will be trying to get out to the range with a couple hundred rounds when the weather improves.

It's known as "Circle Y". Olympic Arms, I used to have one.

Cool thanks for the info.
