AR15 firing pin retaining pin - where locally?

[Strychnine]

Anyone know where I can get one locally?

Or maybe one of the solid crossbar retainers (non-cotter pin style)?



Preferably near Arlington?

Cheaper Then Dirt off of 820 or the Winchester Gallery also off of 820. Pretty much any decent gun store worth their salt should have a piece like that laying around. I was able to pick up a pack of DPMS springs from CTD when some of the springs in my lower were getting weak.
