The HRA SG I picked out at the NS was nice, the SA SG I bought mail order looked like hell but met grade. It had a lot of finish missing (none on the Gas Cylinder), the stock was sound but beat (but appeared refinished at one point), Buttplate was rusty, ect. The barrel met grade which I think is what they really look at.
I refinished the stock, reparked the buttplate, had Tony G reblue the gas cylinder, and sold it for a VERY modest profit, just to move on from her.
