At the turn of the 20th century, the epitome of light weight .22 rifles was created. Behold Remington No. 6. This particular example was built in 1906 and has been my trapline and woods rifle for decades.
For those not familiar, it is a takedown single shot, swinging block action, exposed hammer rifle. It features fixed open sights and a flip up adjustable peep sight on the tang. The takedown mechanism is simple, sturdy and straight forward. One simply brings the hammer to full cock, open the swinging breach block, and unscrew the knurled bolt which vertically traverses the receiver and threads in to a threaded stub machined in to the bottom of the barrel. Remington also chambered this rifle in .32RF, as well as a smooth bore .22RF version which is rare as hens teeth. Later, there was the No. 6 Improved, which was a sign of the times during the depression era when nothing was really improved, but rather was cheapened to keep the price point and profits maintaining the status-quo. The receiver was slimmed down vertically and gone was the tang peep sight. Some or the late production No. 6 Improved's did however feature an adjustable rear sight. All in all, even the cheapened Improved version is arguable of better quality than any other boy's rifle of its time through present day.
