Looking for an NM .050 square A2 post in both the standard 0.270 as well as the extended 0.300 height

My google foo is weak, as I have only been able to find round or tapered posts. DPMS used to make exactly what I was looking for instandard heights (https://www.midwayusa.com/product/1003345718?srsltid=AfmBOooTNOrgGG3-diAe3DyJpiq9cZTgz9H_Bdm6qFhgdCnFREKk5Xlb&pid=844511), but need to find an extended height sight as well.

Any leads are appreciated.

RRA only has the tapered style and white oak no longer appears to carry any a2 sights for servicle rifles

@sinister it would be much appreciated, thanks!

Really?! Thats a bummer, I have a pinned A2 upper from them that is probably my favorite set up.

Try KNS precision. They have many sight posts.  Maybe one will work for you.  I never contacted them one on one to see if they would do any custom work.  I think their claim to fame is non rotating hammer/trigger pins.  I took the OEM pins out of my HBAR and put the non rotating pins. They were .170 and OEM pins were .169.  Not much diffetence but a little tighter.

They do not make what I am looking for.

10 years ago these were still very common.  15 years ago they were EVERYWHERE, now I can't find a one. LOL

Maybe not 0.050 but these are available from Brownells.

Old tech, they all shoot 4.5x scopes now. FWIW, its pretty easy to trim down a spec .070" one, the NM ones weren't really square they were wider at the back than the front. The top back was also taller than the front to improve silhouette by reducing glare.

Yeah most are the tapered style, fulton and rra still sell that style, but the dpms one was square

Maybe try Fulton Armory if they are still around.  They used to have a lot of older style AR parts.
