The Upper Receiver Assembly of the M16 rifle is secured to the Lower
Receiver by a Take Down Pin at the rear of the Receiver and by a Pivot Pin
located at the extreme forward end of the Receiver.
The front sight on the AR-15/M16 is secured to the barrel by two tapered
pins. These pins are driven into the front sight from the right side of the rifle
(as viewed from the rear), and are often very firmly seated.
Various components of the AR-15/M16 rifle are assembled with specific
amounts of pressure or torque. Less torque than is recommended by the
manufacturer could result in a loose or insecure component; excessive torque
might damage the parts.
The M16 and many commercial clones of the AR-15 use a Pivot Pin secured
in the Lower Receiver by a spring-loaded detent to join the Upper and Lower
Receiver assemblies. Brownells M16 Pivot Pin Detent Installation Tool is
designed to make installation of the Pivot Pin, the Pivot Pin Detent and
Detent Spring quick and easy.
This specially designed punch removes the bolt catch pin from the lower
receiver magazine housing with virtually no chance of damaging either part.
Please note there is a projection, or vertical ridge, slightly forward of the bolt
catch, over the magazine well.

The AR-15/M16 Barrel Nut Alignment Gauge facilitates the proper positioning
of several components when installing the barrel onto the upper
receiver. The barrel of the AR-15/M16 is secured to the upper receiver with
a threaded barrel nut.
The AR-15/M16 Sight Tools make movement of sight adjustments much
easier and quicker than the field method using the point of a bullet. The

of the small tube that extends down over the Front Sight.
