This one for sure because the original serial number was scrubbed and that doesn't look like MO font. It's not like scrubbing the bolt group to match or anything, they went for the original serial number. What's funny is that the bolt group doesn't match but looks like it's been buffed or scrubbed tooIs it illegal that the serial number appears to be scrubbed from the receiver?
To me, the size and the font of the stock numbers look awfully good and it appears to be Steyr stock, but I've never seen a receiver with a rough ground area before on one of these.
Where's Mr. Farb when you need him?
