Junnie,
Buy one of the Mauser $20 front sight adjustment tools on Ebay rather than beating on it with a hammer. You can make very small adjustments without moving the sight too far and possibly making a loose fit. It also helps to put a drop of penetrating oil on the sight the day before taking it to the range.
found tool, for 18 dollars,,,, Danke.
how about new taller front sights????
also looking for USMC shooting jackets 1966 we used at Camp Edison. found several but: size small,,, I put on a couple of pounds since 66. more than likely XL or Large.... tempted to purchase the small for my grandson... Danke.... Junnie
also perhaps will be looking for taller front sights, I saw someone selling several weeks , but alas my memory fails.. Danke Junnie
