I ended up getting this 50AE Savage in a trade the other day and I know ZERO about Savage rifles.
At first I thought it was a Model 12 LRPV Right port, but the pics I see on GunBroker show those rifles have small ejection ports and are not wide open on top like this one.
Also, the bolt body appears to have two heads on it. What's up with that? It doesn't look factory.
