How to I.D. AR 15, M16 & Mil Spec Bolt Carrier Groups

Great information thx

I cannot tell ypu how happy I am to have come across this video. Great job on this. I do not take my time to comment on ANY videos I view. I foubd out that I have an M-16 BCG. Couldnt be more thrilled.

Primary Arms 7.62*39 bolt I just got is staked.. by a toddler with a toy hammer.

I got a Failzero BCG that came with my Radical Firearms Upper, which is an M16. was wondering are the failzero's quality or junk? thanx

he sounds like Col. Dale Dye………….

Not a rookie explaining this in his bedroom LOL..thanx for your knowledge. I am looking at a new BCG now.

Excellent job!

Great info On bolts / bolts carries. 👍

Nice video very informative.

Thank God that my Eagle15 has the M16 BCG.

I'm about to retire from the Army, and would never, for the life of me, use an AR15 platform. Complete trash.

I never really saw the entire point of a good stake job on the gas key, but it makes complete sense now. Good video.

Your bolt is so dirty, it's really irritating me.

Excellent Job 。。。

Learned so much here

Thanks for another great video. It sure helped me to know what I am looking for.

Slow down to all you Colt haters. SootchOO said "and it's not in all Colt rifles" at 3:44. I see others of you also noticed your Colt bolt carrier group is like mine: stock out of the box from Colt in about 2015 with an M16 carrier group.

Thanks! clear, consice, and to the point. I subbed

Number?
Whatsapp?

I bought a bushmaster yesterday and it has an m16 bcg in it. That’s what I love about bushmaster

Sootch rocks

Why I won’t ever buy a Colt. When you side with tyranny willingly, you are a fascist by definition

California, New York, Connecticut, and any other of these socialist ruled shit holes, along with our federal mafia government are a result of citizens doing nothing to protect the constitution while this diseased stupidity has run rampant within our country’s government, and states! The constitution is only as strong, as the people upholding it because the people are the constitution of this country! A piece of paper will not protect us from our corrupt government, or anti-gun socialist sodomization because socialism is equal victimization of a society, and the epitome of human stupidity! Socialism is the largest criminal entity in the world that controls half the globe! Now they want to rape liberty’s ass with a good old socialist gangbang! They spread oppression disguised as equality, and because stupidity attracts stupidity, most fools are too dumb to see it, while the people that do see end up with Stockholm Syndrome! There is no choice between being a slave to socialism, or a whore because it is the same thing! This disease has infected half of the globe, and is within the walls of our country because of fools like Obama, and the Clintons encouraged it unchecked! We did nothing, and we are paying, for it! People it is time to run this socialist stupidity out of our country because if we don’t our guns will be gone! Gun owners unite, and spread the message! This is my rifle there are many like it, but this one is mine, only upon my last breath will I be disarmed because death himself is the only being that holds this right over me!

Informative and easy to follow. Thanks

Thanks for this- I've been entertained and informed!

ATF archive allowing no M16 Carrier unless it was modified to Colt SP-1 AR-15 configuration. https://www.atf.gov/firearms/docs/atf-national-firearms-act-handbook-appendix-b/download Excerpt Below:
In order to avoid violations of the NFA, M16, hammers, triggers, disconnectors, selectors and bolt carriers must not be used in assembly of AR-15 type semiautomatic rifles, unless the M16 parts have been modified to AR-15 Model SP1 configuration. Any AR-15 type rifles which have been assembled with M16 internal components should have those parts removed and replaced with AR-15 Model SP1 type parts which are available commercially. The M16 components also may be modified to AR-15 Model SP1 configuration.
It is important to note that any modification of the M16 parts should be attempted by fully qualified personnel only.

I have a class 3 lightning link and the Colt SP-1 Bolt Carrier is squared off instead of a radius cut in the bottom rear of the carrier to the right and left of the center slot. This lets the lightning link paddle fit flush to the rear of the carrier surface and pinches the paddle of the linker flush in between. https://savannaharsenal.com/armory/rifle/ar-15-m4/bolt-carriers/

It used to be illegal to have any M 16 part in an AR15,and was considered a machinegun before the ATF changed the rules. I sat through that ATF meeting. Bushmaster would not sell you an M16 bolt group unless you had a Class 3 copy of your paper work for several years.

I wish you had a piston driven BCG like in a lwrc or adams arms

Looks like someone's skipping the cleaning lol

I loved the comment "Colt is reminding us that we're subjects".
The entire time you were describing the cutout I'm sitting here like, god damn government always trying to control shit.

Would miss you , for sure if you stop making these videos. Lot of knowledge. Going over to your patron page this evening. Thank you …

Does Windham do those special testing procedures

Great video. I've been without an AR-15 for over a decade and this was an excellent refresher on bolt take down and differences.

The colt cut looks like a horse shoe maybe that's why?
