I have a few I bought from an FFL dealer overstock a few years ago. Some are the FA carrier (which is nowadays legal to use in a SA AR, except in California), and some are SA carriers. Only two of the SA carriers have had 250rds or less thru them, but the rest are new, never been fired. No firing pin, firing pin retaining pin, bolt cam pin, or bolt assembly. All gas key screws are properly staked - I can vouch for this because I've been using 2 of the FA's and 2 of the SA's for years now with no issues, with well over 2500rds in 2 rifles, and 1500rds in 2 other AR's.
Any idea what the new FA carriers might go for on EE, and the 2 used SA carriers (250rds each)? Again, there's no bolt assemblies... Just trying to figure out a good price point.
(Also, to the Mods - my apologies in advance if its not right to post this here. I couldn't find anywhere else to ask; so please advise if I'm doing somethign wrong.)
