Disassembling the Browning BAR

Step 1: Unloading the firearm

Before disassembling any firearm, it is crucial to ensure that it is unloaded. Remove the magazine (if still inserted) and visually inspect the chamber to verify that there is no round present. Always prioritize safety when handling firearms.

Step 2: Removing the bolt

To begin disassembly, pull the bolt handle all the way back, allowing the bolt carrier group to move freely. Rotate the bolt handle upward until it locks into position. Next, push the retaining pin located at the rear of the receiver from left to right. This will release the bolt and allow you to remove it from the firearm.

Step 3: Breaking down the receiver

To break down the receiver further, depress the takedown button located on the left side of the receiver, just above the trigger guard. While holding the takedown button, pivot the barrel and gas system assembly downward, away from the receiver. This will separate the two main components of the firearm.

Step 4: Removing the magazine and trigger assembly

With the barrel and gas system assembly removed, you can now remove the magazine by pulling it downward and out of the firearm. Additionally, the trigger assembly can be removed by pushing the two retaining pins located on either side of the receiver. Once the pins are pushed out, the trigger assembly can be lifted out of the firearm.

Step 5: Taking apart the barrel and gas system

To disassemble the barrel and gas system, first ensure that the firearm is in a safe and secure position. Using an armorer’s wrench, unscrew the barrel nut located at the front of the gas block. Once the nut is removed, the gas block, piston, and other components can be disassembled and cleaned individually.

Now that you have successfully disassembled your Browning BAR, let’s move on to the cleaning process.

Cleaning the Browning BAR

Step 1: Cleaning the barrel

Start by attaching a bore brush to a cleaning rod and soak it in gun cleaning solvent. Insert the rod into the chamber end of the barrel and push it through, ensuring that the brush makes contact with the entire length of the barrel. Repeat this process several times, applying additional solvent and using clean patches to remove any fouling or residue.

Step 2: Cleaning the receiver and bolt

Using a soft brush or cleaning patches soaked in solvent, clean the inside of the receiver and the bolt carrier group. Pay close attention to the extractor and ejector, as these areas tend to accumulate dirt and debris. Use a punch or drift pin to remove any stubborn fouling or residue.

Step 3: Cleaning the gas system

The gas system of the Browning BAR is a critical component that requires regular cleaning. Use a nylon or brass brush to scrub the gas ports and gas piston, ensuring that they are free from any obstructions. Wipe down the gas block and other gas system components with a clean cloth soaked in solvent.

Step 4: Lubricating the parts

After cleaning, it is important to apply a thin coat of gun oil or lubricant to all moving parts to ensure smooth operation. Pay close attention to areas such as the bolt, trigger assembly, and gas system components. Be sure to follow the manufacturer’s recommendations for the appropriate type and amount of lubricant to use.

Inspecting and Maintaining the Browning BAR

Before reassembling your Browning BAR, it is important to inspect all parts for wear and tear. Check for any signs of damage or excessive wear, such as cracks, dents, or corrosion. Address any issues promptly to ensure the safe and reliable operation of your firearm.

Reassembling the Browning BAR

Step 1: Reassembling the barrel and gas system

To begin reassembly, reverse the disassembly process by attaching the gas system components and screwing on the barrel nut. Ensure that all components are properly aligned and tightened to the manufacturer’s specifications.

Step 2: Installing the magazine and trigger assembly

With the barrel and gas system reassembled, you can now insert the magazine back into the firearm. Then, carefully place the trigger assembly back into the receiver, making sure that it is properly seated.

Step 3: Assembling the receiver and bolt

To complete the reassembly process, pivot the barrel and gas system assembly upward, aligning it with the receiver. Push the two components together until they fit snugly, and ensure that the takedown button locks into place. Finally, reinsert the bolt into the receiver, making sure that it is fully seated.

Testing and Fine-tuning

After reassembling your Browning BAR, it is important to test its functionality. Check for proper cycling and operation by manually cycling the action and dry firing the firearm (ensuring it is pointed in a safe direction). Additionally, take the time to fine-tune any adjustable components, such as sights, to suit your preferences and shooting style.

Safety Precautions

Handling firearms with care is of utmost importance. Always follow basic firearm safety rules, such as treating every firearm as if it is loaded, keeping your finger off the trigger until ready to shoot, and pointing the firearm in a safe direction at all times. When disposing of cleaning materials, be sure to follow local regulations and guidelines. Finally, store and transport your Browning BAR in a safe and secure manner to prevent unauthorized access and accidental discharge.
