Disassembling your AR-15 bolt carrier group (BCG) is a crucial part of proper rifle maintenance and cleaning. Regular disassembly allows for thorough cleaning, preventing malfunctions and ensuring the longevity of your firearm. This guide will walk you through the process safely and efficiently. Always ensure your firearm is unloaded and pointed in a safe direction before commencing any disassembly or cleaning.
Tools You'll Need
Before you begin, gather the following tools:
- A punch: A small, sturdy punch (brass is preferred to avoid marring the metal) will be necessary for removing the firing pin retaining pin.
- A cleaning rod: This will aid in pushing out the firing pin. (Optional but helpful).
- A magnetic parts tray: This will help you keep track of the small parts and prevent loss.
- Your AR-15 BCG: Obviously!
Step-by-Step Disassembly
Note: The specific steps might vary slightly depending on your manufacturer, but the overall process remains consistent.
1. Remove the Bolt from the Carrier:
This is the easiest step. Simply grasp the bolt and pull it straight back out of the bolt carrier. Set the bolt aside in your parts tray.
2. Remove the Cam Pin:
Locate the cam pin, a small pin usually positioned near the rear of the bolt carrier. Using your punch, carefully tap the cam pin out from the opposite side. The cam pin will likely fall out. Be sure to catch it in your parts tray!
3. Remove the Firing Pin Retaining Pin:
The firing pin retaining pin is a small pin located at the rear of the bolt. Carefully insert your punch into the small hole at the rear of the bolt and gently tap it out. Again, use a brass punch to avoid marring the metal. The firing pin should remain in place, only the pin will be removed.
4. Remove the Firing Pin:
Now, carefully push the firing pin out of the bolt from the rear. A cleaning rod can be used to gently push it out if needed. Catch the firing pin in your parts tray.
5. Disassemble the Extractor (Optional):
Some AR-15 owners further disassemble the extractor. This requires a small amount of force and you'll need to be sure to note the correct orientation during reassembly. This step is not strictly necessary for a basic cleaning, so if you're unsure, leave this part intact for now. If you do choose to remove it, be careful; it's a small part!
6. Thorough Cleaning:
Now that your bolt carrier group is disassembled, you can thoroughly clean each component. Use a suitable gun cleaning solvent and brush to remove any carbon buildup, fouling, or debris. Pay close attention to all the small parts like the firing pin and extractor.
Reassembly
Reassembly is the reverse of disassembly. Remember to carefully align all parts and use gentle pressure to avoid damaging components. Consult a visual guide or video if you encounter any difficulties. Incorrect reassembly can lead to malfunctions, therefore taking your time is key.
Safety First
Remember, firearms safety is paramount. Always treat every firearm as if it were loaded, even if you know it's not. Practice safe gun handling procedures at all times. If you're unsure about any step, consult a qualified gunsmith or experienced AR-15 owner. This guide provides helpful information but is not a replacement for professional guidance.
