Step L5: Safety Selector Installation
Objective: In Step L5 of upper receiver assembly, we will install the safety selector assembly into the lower receiver.
Tools Required
1: A mag well vice block is a good way to secure your lower during the installation of small parts.
Components Required
| Quantity | Component |
|---|---|
| 1 | Lower Receiver |
| 1 | Safety Selector Switch |
Instructions
Secure the Lower
If using a mag well vice block, install a mag well vice block into your vice and install your lower receiver onto it.
Step L5.0: Remove Existing Safety (replacement/upgrade only)
If you are replacing your existing safety selector (or need to remove it for any other reason), first ensure the firearm is unloaded.
You will need to remove the pistol grip.
With the grip removed, you will be able to remove the safety selector spring and detent, and then remove the safety selector.
For standard safety selectors, pull the selector switch out on the left side of the receiver.
If you are removing an ambidextrous safety selector, you will need to remove one of the switch levers. Depending on the safety selector manufacturer, you may need a specific tool designed for this purpose. For example, removal of the Radian Talon ambidextrous safety requires the use of an included detent tool to remove either lever. If you do not have this tool, you can use an unfolded paperclip.
Step L5.1: Assemble Safety Selector (if required)
As applicable, assemble the safety selector according to the manufacturer’s instructions.
NOTE: If the safety selector has the option for short throw or standard throw, be sure to orient the shaft and levers of the safety selector properly. The detent channel on the shaft should be on the right side. The detent channel for desired throw should be facing down (short channel for short throw; long channel for long throw). The levers should be facing to the rear.
Step L5.2: Lubricate the Safety Selector
Wipe a thin layer of lubricant on the shaft of the safety selector assembly.
Using a needle dropper, place a small drop of lubricant in the detent channel. If you are using a safety with both short and long throw options, lubricate the appropriate channel. The short throw channel is the smaller channel; the long throw is the larger channel.
Step L5.3: Insert Safety Selector
Insert the shaft of the safety selector into the lower receiver.
For standard non-ambidextrous safety selectors, be sure that the lever is on the left side of the lower receiver.
Step L5.4: Finish Assembly of Safety Selector (if applicable)
If using an ambidextrous safety selector, install the second lever according to the manufacturer’s instructions.
HOLD OFF ON THE DETENT AND SPRING
We save the installation of the safety detent and detent spring until the installation of the pistol grip so they do not get lost.
