Ep-7: How Does the AR-15 Bolt Carrier Group Work? Which One Do You Need?

The extractor o ring can give people trouble in cold weather. It's small over looked part. But it can make all the difference with bolt going into battery. Which leads most to think its a problem with spring or weight and not with the extractor.

Look at the camera

what happened to ep 8 on lowers?

Is this the same guy from the salt water fish tank videos

Thought this was a lightsaber comparison test at first

Great Video. Getting ready to buy some Nickel Boron BCG's for my older AR's and this video was a huge help in that! Keep doin what ya do Patriot

Is number 8 missing? Looks like it goes right to 9??

Because the ar15 is chambered for 556/223 the barrel is milled accordingly. How accurate can a 9mm or 22lr round be just because the bolt is changed for that round? with all the tolerances being as they are its hard to fathom the round not jumping around going down the bigger bore barrel? Did I make any sense?

Great information. I encourage everyone to watch this build series

Thank you for the great breakdown. This whole series has been amazing!

Mine is boron nitride a fully automatic machine gun part will I be arrested?

For a youngster you are very knowledgeable and you speak well also. Kudo's to your parents. Well done.

I went with Lantac E BCGs & Silent capture buffers-- AWESOME smoothness & reliability !

I prefer Cryptek Mystic Black CVD coated bcg's because they are much easier to clean, nothing sticks to them, nothing is more wear resistant and nothing is slicker. I also like there precise machining tolerances they keep as close as we do in the benchrest world. 2nd choice is Iron City Rifle Works Black Diamond bcg

Directions unclear. BCG stuck in protein skimmer

Hay Randy glad to see your doing videos again. Lol youve just move to my most expensive hobby. As as always great job.

Nickel boron is a terrible coating, mil spec is hard to beat and can hold oil better than most of the newer finishes..Chrome plated carriers are excellent if done correctly..It is more important if the bolt and carrier is machined correctly with the proper 3 bore dimensions and length..

Can any bolt Carrier and charging handle fit on my 5 inch ar15 ?

Great videos! What happened to 8?

I just found this channel and as I started this video I was putting some things away and I recognized this voice. I said to myself, “That sounds like Randy from BRS.” Low and behold, it’s Randy! Awesome how the interests cross over. Glad to see you over here Randy!

ALL I want out of my AR-15 and the BCG is to build it to be combat ready in other words to be able to run at any given time for any reason

The heart of your firearm

As always, very informative 👍👍
