i picked up 6 of the RIA's with no stocks.
i had a bunch of old wood and hogue stocks laying around from previous builds to i just chucked them into those.
i did a big write up about it..... last winter i think it was???
anyways, the only bad thing i found in the 6 i cleaned up was the bolts.
take your apart and im sure the bolt is nasty, they all are.
invest 10 minutes with some 1500 grip wet and a buffing wheel and it will run like a top.
3 of the ones i picked up went to co-workers and 1 went to my dad, i kept 2 for my kids when they get a bit older.
i only put a couple boxes through each to function check them but i didnt have one hickup with any of them.
solid guns.
they based them on the early 80's Ruger from what i could tell.
