Fun Gun Reviews Presents: “How the AR 15 Bolt Carrier Group Works”. This is No. 4 in the How to AR-15 Series. Demonstrating how the BCG interacts and locks with the barrel, How the Direct Impingement system relates to the BCG and details about how the charging handle functions.

Thanks for the info. I'm new to the AR family.
That was really good Sootch, thank you. I learned a lot from this video as well your trigger video.
ohh thank you for your video. maybe I need to try my charging handle. http://www.ohhunt.com/ohhunt-ar-15-cocking-charging-handle-extension-m4_p1573.html
Besides the in-line buffer system, I think the rotating bolt (copied from the Johnson M1941) is probably the most ingenious part of the AR-15 design. Having seven different locking surfaces makes it EXTREMELY consistent and more accurate than most other semi-automatic rifles. Nobody expects their G3 or their FAL to be 1 MOA, but that's not unreasonable if it's an AR.
Fantastic explanation

Thank you for the video. Really enjoyed it.
Thanks for teaching this newbie, Sootch!
That was a great review but I have a question. When the rear break down pin is pulled to remove the bolt carrier group and charging handle, is the bolt carrier supposed to come without releasing the charging handle? I have the CMMG conversion kit with the new charging handle as well as the bolt carrier and charging handle for the .223. They both fall out without releasing the charging handle. Thank you
Thx!
outstanding video!
very cool man thanks.
Awesome! gonna get one soon and trying to learn all i can. thanks.
Excellent video — everything well explained, Thank you.
Very well explained, thanks so much.
BCG = Birth Control Glasses
It sure does shit where it eats. Aerosol CLP sprays really come in handy. I put together a 450 Bushmaster AR-15 so I would have faster follow up shots on large game. The 450 BM is a straight-walled big bore cartridge therefore it can be used for hunting whitetail in over 30 states. If it weren't for Johnny Law I might have done a .458 Socom; but 450 BM brass is some tough stuff by comparison.
What makes the charging handle go forward after you pull it back.
What does it mean to charge the rifle?
I've done a lot of research on guns/mechanics…, but I can't recall why the bolt has to lock into the barrel. Is to keep the bolt forward, locked in place until the bullet leaves the barrel? Is it necessary, because of the gas tube?
Excellent! Thanks for the detailed information.
Recently purchased my first AR. I have watched a lot of videos, trying to understand the mechanics so I will know how best take care of my investment. This is the best video, by far. Thank you..
Simple instructions now extra talk. I wish all YouTube videos were like this. Straight to the point thank you.
years later…. what multitool was that at the end of the videos next to the bcg's you had lined up? thanks.
What a man! Thank you!
Thanks for the video.
Very informative! Thanks for the video. I am just getting into the AR scene and this video helped me understand the workings.
thank you very much sootcho!
what is that small round stud in the front of the bolt opposite of the ejector near where the firing pin comes out?? what's it called and what does it do?
beautiful design. I salute your patriotism sir.
have you ever built a 7.62×39 upper? would be a great video
how important would you say having a quality bcg in your rifle would be? I bought a nickle boron bcg instead of the original black nitrate. do you think it was unnecessary?
Excellent explanation , but I still have one doubt. The gases in an impingement system enters inside the bolt to help unlock the bolt , but this eventually causes fouling. My question is if this is really necessary because on a piston system ar rifle, the bolt is unlocked only by the rearward action. In an impingement I would rather have the gases redirected to bleed to the exterior of the bolt and not foul the inside. I believe the piston system proves this is unneccesary. Wouldn't you agree?
Thank you sootch00, this helps me with the understanding of the AR's action.
AR-15s are cool as hell the way they work they way they look everything about them i have an sks but realy whant one of these to bad i dont got my restricted pal yet
lol…Teeth 🙂 Locking lugs!
