If it is in excellent condition (no rust, metal finish good, no major scratches on the wood) it could be worth $300 to $500. If it has what is called the Rutledge bore which means the last several inches of the barrel at the muzzle are opened up to larger than .22 caliber to pattern the shot better it could be worth considerably more to a collector.

The value of an old firearm depends almost entirely on condition and desirability. In the case of the Remington 510 it is a very desirable 22 cal., rifle. The 510 is light, short and very accurate. It may be one of, if not, the finest training rifle ever made for young shooter/students. When the bolt is thrown on a 510 the safety automatically goes to the safe position, unlike the other Remington 500 series bolt-action rifles. A 100% original 510 in excellent condition, with a good bore and no external rust or pits will bring $175.00 to $225.00. As the condition worsens, the price goes down accordingly. I have bought "dogs", just for parts for as little as $50. Ed
