Step-by-Step Disassembly Instructions

Before beginning, ensure the firearm is unloaded and safe․
Start by removing the forearm, often held by a screw or latch․
Next, with the action open, carefully slide the barrel forward and off the receiver․
After the barrel is removed, focus on the bolt assembly․
Retract the bolt and locate the bolt handle; remove it by pulling rearward while using the link to push the bolt forward․
The bolt assembly should now slide out․
Finally, proceed to the trigger group, typically secured by pins that must be carefully punched out from left to right․
Remember to keep parts organized!

Removing the Barrel

Before attempting to remove the barrel, always ensure the Browning Auto 5 is completely unloaded and that the chamber is empty․
With the firearm confirmed safe, begin by field stripping the shotgun to its basic components․
This generally involves removing the forearm first․
Once the forearm is detached, locate the barrel retaining mechanism, which may vary slightly depending on the model․
Typically, the barrel is held in place by a friction fit or a simple locking system․
Carefully grasp the barrel near the receiver end and, while applying gentle pressure, slide it forward, away from the receiver․
Avoid using excessive force, as this could damage the barrel or receiver․

Disassembling the Forearm

Disassembling the forearm of a Browning Auto 5 requires careful attention․
First, ensure the shotgun is unloaded․

The forearm is typically held in place by a combination of friction and a retaining mechanism․
Begin by gently pushing the forearm forward, towards the muzzle, to relieve any pressure․
Next, locate the forearm retaining latch or button, often found on the underside of the forearm․
Depress or manipulate this latch to release the forearm from the magazine tube․
Once the latch is disengaged, carefully slide the forearm forward and off the magazine tube․
Be mindful of any small parts, such as friction rings or springs, that may be housed within the forearm assembly․

Removing the Bolt Assembly

Removing the bolt assembly from a Browning Auto 5 is a crucial step in the disassembly process․
Begin by ensuring the firearm is completely unloaded․
With the action open, locate the bolt handle;
While pulling rearward on the bolt handle, use the link to push the bolt forward․
This maneuver will help to disengage the bolt handle from its locking position․
Once the bolt handle is disengaged, carefully slide the entire bolt assembly forward and out of the receiver․
Pay close attention to the orientation of the bolt and any associated parts, such as the locking block or rollers․
These components may become dislodged during removal, so it is important to keep track of their positions for reassembly․

Trigger Group Disassembly

Disassembling the trigger group of a Browning Auto 5 requires careful attention․
Before starting, ensure the firearm is unloaded and the bolt assembly has been removed․
Locate the pins that secure the trigger group to the receiver․
Using appropriate punches, carefully drive out these pins from left to right, as this is the standard direction for pin removal in this firearm․
Once the pins are removed, the trigger group should be able to be carefully detached from the receiver․
Be mindful of any small parts or springs that may be under tension․
Disassemble the trigger group in a clean and organized workspace, keeping track of each component․
Take photos or make notes to assist with reassembly․

Detailed Instructions for Each Component

Once the trigger group is disassembled, focus on each component individually․
For the hammer, inspect for wear or damage on the contact surfaces․
The sear should be examined for any rounding or chipping that could affect its engagement with the hammer․
Carefully clean each spring, ensuring there is no rust or debris hindering its function․
The safety mechanism should be inspected to confirm it moves freely and engages securely․
Each pin must be checked for bending or damage․
Note the orientation of each part as it is removed to aid in reassembly․
