Remington Nylon 66 22 Rimfire Semi-Auto Rifle Review

Rear Sights, Sight Adjustment, Nylon Seams
Remington Nylon 66 rear sights.

Two Remington Nylon 66 rifles' rear sights. The rear sights are mounted to the stamped sheet metal receiver cover, not the barrel, but these rifles still provide good accuracy. The rear sights are adjustable for windage and elevation.

The Nylon 66's rear sight is fully adjustable for windage and elevation, and is of a good design.

This very simple, very practical system features a rear sight which it held to the receiver cover (not to the barrel) by a single rivet. A windage adjustment screw is retained in a static position at the sight's rear; this screw engages with grooves stamped into the receiver cover. When turned, the screw pivots the rear sight on its rivet.

Speaking of the windage screws, you may note that they are different on these two rifles. The Mohawk Brown gun on the left was made in 1959 (the year of introduction), and the Apache Black on the right was built in 1971. The early rifle has a large knurled head (with wide slot) on the windage screw, ostensibly to aid in adjusting the sight by hand. The photo also shows, though, that the early screw is bent.

Crooked Screws

Bent screws must have been fairly commonplace, because the large head had been eliminated by the time the 1971 gun was produced. That rifle's windage screw has just a small stem with a very thin slot cut into its end; adjustment requires a small, thin, flat-bladed screwdriver.


Elevation adjustment is easily accomplished via finger or coin (the crossed slots in the elevation adjustment screw are radiused for a coin). The coin slots, though, could have used a bit more forethought; their thickness is just about right for a penny, but the radius more matches a dime's diameter - and a penny hits the vertical portion of the sight when used to turn the screw. But the elevation screw is easily turned by hand on both of these rifles, anyhow.

Hiding the Seam in Nylons

This photo also shows another clever thing. The Nylon stocks on these guns were made in two halves, and fused down the middle, lengthwise. That, as we all know, produces a seam, which is often unsightly. To hide the seam, Remington simply cut a narrow set of grooves down the length of the stock on top and bottom, neatly concealing the seam while resembling grooves found on barrel ribs of shotguns and rifles of conventional design. Nifty.
