AR-15 Bolt Carrier Group Disassembly & Reassembly

Would be better if the other guy would stop chiming in. Annoying voice too, All he did was help lose my train of thought watching you do the assembly/ disassembly. One question : Should the bolt be forward sticking out of the carrier or pushed into the carrier when inserting the firing pin and pin retainer?

Emphasize the bolt needs to be out all the way to put the cotter key back in.

Thank you this arbi just got was filthy

after how many rounds should it be cleaned?

Thanks fellas. Your video was easy to follow. Now to find a video where You show us how You like to lube the BCG.

I use Krytox grease on mine. Light coat of that stuff goes a long way. Tube I have retails at 1800 bucks luckily I worked for Dupont and knew a guy who worked at the Krytox unit. Shit is amazing wheel bearing NEVER ware out any metal to metal contact becomes nonexistent.

Unload your rifle of all ammo, and Magazine…TRIPLE CHECK to make certain,if ..the carrier group is not going into the receiver ..make sure to twist the (cam pin) forward ..which will extend your bolt out to about an inch..then re-insert the (BCG) into the receiver..should have no issues..then function check safety, and fire, ..just like the video is showing here…

very nice

Thanks for the refresher. Been 25 years out of the Marines.

cool thanks for the video very helpful and very easy

What do you think about 0-158 LSA weapons oil? mil spec MIL-L-460008?

Your video was key to completing my reassembly.

Thank you

thanks bro it's been about a decade since I've had to take one apart

I'd add cleaning the extractor as the standard. One pin to punch out. There is always brass caked in there

Thanks for the refresher. Been 40-ish years since I cleaned one of Uncle Sugar's M-16s… 😉

thanks for the tip it is perfect to disassemble my nickel boron when im done shooting at the range

best video i seen in a long time i learned a lot GOD BLESS

Good video forgot the show shells track extractor orientation and inspection I feel this is it important to inspect your bolt face and shell extractor
Other than that great work

you guys are awesome… great video!

Nevermind, it can only be inserted one way because (on mine) the other side is slightly smaller and you can't push the pin in.

Why doesn't anyone say which way the inner bolt should be turned when you put it back in? Since you can spin it around there are two possibilities that allow you to push the pin in. The little ejector sits at a completely different angle though.

Great video- this was what the part confusing me

Excellent.
Thx Dudes!!!
Just bought my 1st AR 15. (Colt 6920. Stamp on Receiver says Colt LE M4 Carbine).
