Are all those holes in the receiver of this rifle original with the gun?

Gunbroker Savage 99EG

I think this qualifies as a live auction to warn folks away from ...

No, none of those are factory. Well, the two far rear screws on the tang are factory (you can see one in this pic), but the other 7 holes aren't. The three top ones on the side are for a side mount, and the 4 on top are for standard bases, but done aftermarket.

Thanks.

Yes, its the rarely encountered Swiss pattern 99. It was fashioned after a block of cheese and made for issue to the Swiss guard to go with their wine. And you all thought the MHG was the Holy Grail of 99s, right? Is it April first yet?

That particular version is known as a "holey terror".

You don't want that gun
