What would make a H&R M1A worth more than a Springfield Armory M1A?

Appears you are correct. Upon further looking, it appears Palmetto ( having acquired the rights to H&R from JJE Capital Holdings after the Remington / Freedom Group bankruptcy dispersal sale ) has done a special retro run of new H&R logo'd receivers with USGI parts for a 60 gun limited run.
However, some of the original H&R M-14 receivers were apparently surplused out at some point - as my former boss had an National Match M1A style that he used in NRA HighPower competition that had been built with an H&R receiver. So, there are some out there.
 
I wouldn't be surprised if the retail on this Rifle is near the 3K mark. I own two M1-A's, am early Springfield (Devine Texas) with a serial number under 700 and a 15 year old Springfield Scout Squad that I put a RDS on.

If I was to ever buy another M1-A, I would buy the Bula M-21 DMR that has a Picatinny rail forged into the receiver to give a much better, solid scope mount option. Even the bula is $2500.00 +.

I do like the newer M1-A manufacturers making forged receivers.

Jje IS palmetto and h&r/nodak, so it's all the same guys/sister companies
