This is my BCG, I purchased it stripped when they first came out. The bolt is a Lantac, firing pin is from ZeroFail, and the cam pin is V7. I've never had an issue with it, and its only been fired suppressed. Thanks Chad for the great work, I really appreciate it.

I think they might have seen your video. Rolled the dice and purchased one anyway. Staking no longer looks like that, and they don't have YFS fasteners anymore. Torque check on the gas key passed too. Thanks for helping me arm myself with ways to test my gear

awesome

Amazing attention to detail. All these decades I have just been pushing the bolt into the BCG and snapping it out a few times to check function. I really need to raise my game.

I've never seen this level of analyzing of a bcg before. I must learn this.

Thanks for this great review. I baught one in 2017, fired nearly 7k rounds, about 2k suppressed. Cleaned maybe 4/5 times. Never had any problems, works great so fare.

Without having gauges, I have an unused one circa Aug 2019. Still YFS screws but much better staking. Regular cam pin but almost the same amount of wobble. Ejector roll pin is sticking out of one side and the sticking out side is somewhat mangled. Will fix the roll pin and replace the cam pin. Edit: Chad, you just saved me. The roll pin is so mangled I can't get it in any further. It also protrudes so far that the bolt won't lock closed. This is going back to Bootleg and they can replace it.

Your like bcg whisper lol learning a lot

I have one on a BCM 556 11.5" upper, Geiselle charging handle, and a YHM Turbo suppressor. With the Bootleg bolt setting to suppressor, it has run reliably. No gasses leaking out the back. I am very happy. Wonderful setup. Makes a great alternative to a gas adjustable block.

Very Nice, Very Educational as always! Thanks for all you do to help us make wise decisions.

Excellent video. Very informative and enlightening. Nice clean work environment, nice organization.

I got a bushmaster varminter years ago (used) . I have no clue how many thousands of rounds I shot threw it. when I finally got rid of it. The spring was bad the bolt pin was bending. The bolt was probably at the end of its lifetime. But I tell you what I never had any issues with it. Just didn't like hollow points. Bushmaster makes some of the best ar-15s I've ever shot. I've Shot the center of a dog tag at 228 yards. Golf balls at 200 yards np. I shoot so much I've replaced bolts and carriers like shoes. You have the best video I've seen. Over time you can just look at it and say yep it's gone. Or it still has some life in it., 👍I pawned it for the same price I got it for. 1k

I've been following you on instagram since your page started I think. Had no idea you a have a YT channel!

Would like to see this with a Brownells BCG

Awesome video! Thanks

What must I do to find these bcg gauges?

Always a pleasure

Could you make a tool and gauge list for those of us who would like to check are own ar15 tolerance’s?

That's an older version. The new ones are full auto rated and have side cuts for forward assist.

I wonder if the rubbing on the gas key greatly accelerated wear on the cam pin. Surely that would cause additional lateral stress...

Oh well I just ordered one yesterday, Will be checking over when arrives , funny how this pops up after ordering one

You have a lot of tech toys.

Cool. I have one of these and it runs great, have another incoming for another upper that I will also shoot suppressed sometimes. Both with a supplied bolt. Do you have any experiences/opinions with titanium firing pins?

This is a knowledgeable dude

My experience with a suppressed 6.5 grendel is it does help with gas. As far as durability, looks like from this, it may need some help.

Would like to see BCMs put to the tests like this

Where can i get those rubber orange vise lips ?

Any plans for a SOLGW bcg?

Very nice , magnetic test what does that prove or disprove ?

what do you think of the poly lower with the stock like the m16 from Brownells ?

Looks like a VSeVeN Cam Pin

Just bought one of these on sale and will give it a look-over when I get it thanks to this video. I've got an RC2 working its way through an eForm 4 at the moment and I want to use this in my two ARs (an 18" Geissele HBAR and 13.9" Criterion CORE), both of which have Surefire muzzle devices. Looking at the material for it, it seems that the U1 setting is best for 65-77gr+ rounds? It just seems like this is a much better and more functional solution to gas issues than spending $100+ on a damned Gucci charging handle. So I should be looking at how it's staked and whether I've got one of the older ones with YFS fasteners?

Can you review faxon firearms bcg

was the original gas key and bolt internals chrome lined ?

Whats up with these guages and where can I purchase them

Ever inspect a finished 80% lower ??

That cam pin was borked.

Two questions for your sis ? What's is the best BCG to buy for shooting 556 suppressed out of a 10.5? Also are this Bootleg BCG worth it ?

Here's what I want to know.... it looks like pretty much EVERY bolt you've ever touched was out of spec. Here's my question, if we do this complete inspection ourselves, or send it to you, and one or two items are out of spec, what are we to do next? If the bolts too short for example, we pitch it and then what, buy another one and mic that one too? What if that's out of spec? Now what? Do we keep buying parts and are 45 parts deep before we've assembled a franken bolt thats all now in spec? I'm just curious. Gauging is just the first step, I would like to know what the 2nd step is. Thanks!

so what rating would you give this bcg, average?

SOTAR, I have 2 of these bcg’s. One in a ADM and one in a DD mk18. For some reason the dust cover will not latch shut on the Mk18 with the bootleg installed. I bought a Wilson combat mil spec dust cover and same problem. I ended up taking a dremel to the DD polymer dust cover and sanded down the ball detent housing and got it to latch. Do you know what would cause this? No one so far seems to know

This video gives me no confidence in this BCG. The first release of these adjustable bolt carriers did not come with a bolt. That might explain the NiB bolt in it here and the V7 cam pin. Now the adjustable carrier is a complete group - bolt and carrier.

Hey I've got an idea let's make the most fragile part of the BCG even weaker... genius.

Can you put a 7.62x39 bolt in this carrier and have it perform effectively the same way?

Guys I have an AR that gives me light primer strikes and every once in awhile brass rounds fail to eject. It runs and ejects steel case better but I do get occasional light primer strikes. Where should I look first? Headspace?

Too bad co. See this and dont feel shisty God Bless Corporation of America

Shit , im still firing 303 british no1mk3 1914 shtle. No need for this kind of info yet.

Breath louder into the mic please
