El in on top and windage on the left side, and I have no idea which is the correct direction for the knob to turn. I really did not pay attention to the markings. Setting a scope means looking at the bullet holes through the scope and moving the cross hairs from the bull to the bullet holes. Sorry.
Gibbs claims they had a basement full of A4 bolts from a parts purchase much earlier and uses reclaimed drill rifle actions with new made barrels to seal the deal. I agree that the margins look slim. I even bought mine at a discount from the AIM price.
In many ways it is not a thing of beauty but for the price a reasonable deal. Somewhat of a crap shoot as to what you get in the way of parts such as wood and small parts. I noticed the guns provided to reviewers seem to have original stocks with markings intact. Mine has no markings and is a new stock. This would also be true of many 1903A3s on the market today. The days of $100 Springfields is a distant memory now.
