I have a 2 457s and a bunch of accessories to go with them. They have been very solid.
I have a 20" .22lr threaded barrel on one with a walnut stock for backyard use. And i keep a 20" threaded .22wmr or .17hmr barrel on the second rifle that wears a symthetic stock.
I have the scout wood stock and 16" threaded barrel with sights, which is designed for kids, as well. The rifles are very versatile, 2 screws to remove the stock, 2 more to remove the barrel and you can slide in another caliber. You will have to re-zero but it is usually within an an inch or 2.
I bought the first one and started collecting the barrels for it. Then bought a second scout when it was on sale for $350. These rifles are very popular with the precision group and you can usually find them selling the factory stocks / barrels on different forums.
