There is no built quality difference between El Tigre and a true W92.
El Tigre was built, initially, under agreement with Wichester, paying royalties, until they decided to make certain cosmetic changes to avoid keep paying Winchester.
They have excellent barrels, and with smokeless powder, they will place one bullet over the other from 50 meters distance. I have one and can testify that. With BP the rifling seems tobe more problematic in the accuracy aspect, or maybe I didnt get a good load yet.
Most have seen hard use, thats why people overlook them, forgetting that they were forged, fully machined, from good steel, and rust blued. Mine is 101 years old, it was used until yesterday by a wild boar hunter, and shoots like a champion with factory ammo.
