I have one HRA Service Grade Special purchased from the CMP in 2014. Less than 50 rounds fired since. Service Grade Special means fire control group, receiver, barrel, gas cylinder, front & rear sights, op-rod and bolt are original to each other according to the CMP.
CMP new stock.
Replaced stock metal with era parts, not paying attention to mfg. or year details. I just wanted to get rid of the new gray phosphate stock metal. $1k plus shipping.
