How to Disassemble an AR-15 BCG - PSA Quick Tip
Hey guys, Tye from Palmetto State Armory here with another quick tip video. Today we're going to be disassembling our AR-15 BCG or bolt carrier group. Let's begin.
Parts & Tools Used:
Removing the Firing Pin [00:25]
To start we're going to begin by removing the firing pin retaining pin. I'm just going to grab a hold of it and pull it out from the left-hand side. Next, we'll remove the firing pin, to do so we'll give the back of the carrier a little tap and it'll pop right out.
Bolt Removal [00:40]
Now for the bolt. We're going to push the bolt all the way to the back of the carrier and then rotate the cam pin 90 degrees. This will allow it to escape out past the gas key. Next, the bolt itself. We'll simply pull it out through the front of the carrier.
Inspection and Cleaning [00:57]
Now we want to make sure we give everything a light coat of oil when we go to clean it.
And we want to check for carbon as well. You're gonna wanna check for carbon on the back of the bolt right here on the front of the firing pin right here. And then on the inside of the carrier where the bolt is housed. These three spots tend to have a lot of carbon buildup.
BCG Reassembly [01:21]
Now let's get everything reassembled.
Grab the bolt and the carrier and push the bolt back in. We're going to want to make sure that we keep the extractor on the right-hand side and then line up this hole that's in the bolt with the channel for the cam pin. The cam pin will simply slide right in and then we'll rotate it back 90 degrees as it originally was. We'll pull the bolt forward now.
Now for the firing pin. We'll just come in through the rear of the carrier and then we'll take the retaining pin and pop it in.
Now your BCG is reassembled and ready to go back in the firearm.
