odd possibly Armalite FSB ? > AR-15 / M-16 Retro Forum

Posted: 7/23/2013 2:58:01 PM EDT

Hello Hello,

Came across this unmarked FSB in my junk box, anyone might know what it could be? No markings, the up and arrow are raised with a 5 notch front site post. Almost looks milled or something...

Ill mic it soon as dinner is done. Thought I remembered reading somewhere the really early Armalites were cast... probably wrong though..

Sounds like an Oly Arms sight base.

JT is correct. I have the exact same FSB. It is an Oly Arms product.

Still a nice piece to have even if .750 for a 602 budget clone. Would only offend the true retro guru with authentic early parts. .625 Oly would be more desireable. Those things still bring more than a modern production piece.

Took a closer Look at my baby tonight and realized that green mtn had used a F stamped a2 FSB on my supposedly a1 bbl, thinking I might have to used the oly in mine. Hope the pins like up....

Update,

The pins distances are different, so I'd need to have the bbl redrilled for the oly base, and can't get the a2 one off anyways.
Wondering if anyone out there would recommended someone to send the bbl and the fsb to to have the removal and install?
