Should I use Loctite on my Nosler M21 pic rail?

Nosler M21 Picatinny Rail Scope Ring Options

One of the great benefits of the Picatinny rail (Pic Rail for short) option is that when designated a “Picatinny Rail”, the dimensions follow an established industry standard (MIL-STD-1913 rail). As a result, any scope ring designed to fit a true Picatinny Rail will work on this Nosler M21 Pic rail. Following the picatinny rail spec, Talley Manufacturing offers a variety of Picatinny Ring options to meet the needs of all shooters.


As we look around the world of rifle scopes, we are seeing many manufactures shortening up the mounting surfaces of scopes. These shorter distances combined with the fixed mounting location on the rifle tend to limit the range of eye relief adjustments. This is one of the primary reasons many find their best option to be the pic rail.

With established dimension that repeat down the length of the Nosler M21 Pic rail, the shooter is given the greatest flexibility in eye relief and mounting options over traditional systems such as the weaver base option. The Nosler M21 Pic Rail is a simple solution to achieve the best eye relief when mounting a scope, red-dot or night optic regardless of the mounting surface distance.
