I’m not sure if it’s covered but at 28:00 you’ll notice that the top rails of the carrier extend all the way to the front. On a regular mil-spec the rails don’t extend past the cam pin. This gives the system a lot more stability. As far as the cam pin is concerned, that thing is HARD. I have the newer design and I diamond filed a witness mark so I could make sure to put it back in the same orientation after cleaning. It took forever just to put a shallow barely visible notch on it. Very impressive. This is definitely the best bcg in existence and it is _not_ overpriced

This video reminds me of a great Larry Sanders quote I heard some years ago....."There are two types of people that wear sunglasses indoors, blind people and assholes." So funny that guy.

This guy is excellent at explaining everything. Extremely knowledgeable

Fantastic video. Still waiting on anyone anywhere to post a picture or video of a broken G forged bolt. Everyone claims to shoot thousands of rounds, so we should have seen dozens of broken G bolts by now.

Great informative video. I like the fact that the newer version has a witness mark on the cam pin.

I have one of the first ones that are 'rebcg' engraved and it's by far the most gas efficient bcg I have tried

Did Geissle send you a used bolt? If not, how many rounds were on the Geissle? Sorry if you mentioned this in the video. My memory is not the best.

Centurion Arms has a great BCG too.

The Geissele REBCG is very efficient. I had to add a buffer weight after I got it.

Pull the bolt back on your super duty rifle and look at the cutout for the cam pin, then do the same with a different rifle. You'll see that geissele didn't change the cam pin design on newer rebcgs, they just can't use their cam pin design for carriers that aren't being used in a geissele upper

Mil spec is a set of standards and tolerances set by the TDP spec..Most commercial AR rifles and parts do not meet mil spec, let alone surpass them...The Geissele enhanced bolt is claimed to last 5 times longer than a standard mil spec bolt.. If true, then it might would be worth the cost.. Add the cost of 5 mil spec bolts to one Geissele and you will get your answer..The military changes bolts approximately every 6000 rounds as routine maintenance.. It is the higher residual pressure that caused the bolts to fail with the carbine length gas tube rifles, not dwell time..LMT made the cam pin channel longer (on their enhanced bolt carrier) on the straight part to allow more residual pressure to drop before extraction occurs with the carbine gas tube rifles ..The down side is the enhanced LMT BCG would not work correctly with the rifle length gas tube..

I've tried chrome and NP3 and while they clean better than phosphate, they still are a pain in the ass. How does this compare to chrome and NP3 (Scionics brand) in terms of cleaning? I was extremely disappointed by the Scionics BCG.

Google says all milspec bolts are forged.

You run an EOtech w/o a magnifier on your “DMR”??

So anyone likes super shiny slip I mean I could always put in a proper bowl but I will I don’t know it’s just hard to trust it I mean they want like 350 bucks for the fucking thing I think it’s insane

12:30 Neither the carrier itself, nor the gas key are chrome lined.

Bill Geissele is a genius! He is a true engineer at heart up there with Eugine Stoner and Ed sullivan.

shooting these through a 10.3 though

I’m a lefty and does anyone know if the LMT BCG has a delay letting more of the gasses out and not in your face I’ve got a 14.5 Noveske barrel they say it’s meant for 11.5 and really want work well and then I heard it will help???🧠🤯🔫

This is totally random , there are some "Enhanced" BCGs that are , when accounting for their insane price, total pieces of crap , Lantac comes to mind , "Omg, we have a better looking cam pin, lets charge 300 bucks !!".

REBCG incredibly OVER-PRICED . Look at BCGs from: Modern Armory/BRD Gun Works/Trajectory Arms and even Expo Arms , then upgrade the extractor spring , use the 5 coil Sprinco , if not already present .

Great video. It's just hard to justify the price. I suppose that's something every person has to evaluate on their own. Any thoughts on the JP Enterprises EnhancedBolt? - kzfaq.info/get/bejne/Y5ucfspm05yWeKs.html

There is no way a mil-spec bolt is lasting 20k rounds.

Sand will definitely 100% damage the coating. 80 hrc or not. Sand has every kind of rock you can think of in it, including....diamond and sapphire. So I REALLY dont understand why Geissele would claim sand would not hurt the coating. Such an extremely dumb claim. 🤦 I wonder why they changed the cam pin. Its actually what brought me to your video. I just got one in the mail today. Compared to my other Geissele it didnt have the same cam pin. I prefer the old cam pin design. No worries about not putting it in the same way every time. Now i have to dimple the new one to make sure. 😅

The huge issue is I believe would be something like head spacing which is fucking critical. If you have a too tight of a chamber look up you could share logs off you can have a sloppy bolt carrier and have extreme pressure fluctuations between rounds firing which you do not want when you’re old is Park we had to bass with the BCG having cycling issue pounds basically you could have a high and barrel but if you’re just buying for example a bolt carrier group it’s not the boat itself isn’t matched to anything barrel extension and even if it’s the same company barrel and they’re using it on at like their cup their own companies barrels and their barrel extension they’re still gonna be a variance widely in every extension personally that my beliefs and what I’ve noticed so I get a barrel with the head spaced bolt and then you use the carrier and maybe if the head spacing on the bolt carrier is good and not sloppy not leaning to one side to the other side OK I would use it but buying a $300 BCG not knowing if it is a really strong bolt it’s gonna fucking be properly headspace is a huge issue and it should be a huge issue for everyone know this guy may have a new one but he does not know that he’s going to work in any of his rifles for example like I have a random wife I’m not gonna mention the company but it’s the reputable and it’s sleek chrome polished who’s carpenter 158+ the bolt most companies when you buy a barrel had to go through maybe 50 bolts Defined a matching bolt that headspace is best for you you were barrel extension on the barrel and most high-end companies now I consider them a high end in triggers rail systems you know I mean yes they got the URG contract but that’s a collaboration of different companies so I love their shit I’ve seen unmatched receivers stats even and the price they say those bad rifle at a very high price it doesn’t have any doctors controls the Maritime bowl catches do work for someone like I said it’s a left-handed person but you have to think how many times have you had a carrier that feels just it’s too tight you having issues with Browns cycling you could put any round you want in in the cycle and the funny thing I put my one BCG touches that I don’t know where it is only thing I will work on was one upper oh fuck I mean I’m talking it wouldn’t work on anything and I have a lady in my one OK builds with $800 barrels to Noveske a and my just plain Jane Mehl spec stuff and his company and utilize for all of my trigger and you said buffer systems but if I didn’t know anything about headspace saying sure I would get it has DLC is what can you use the coast to phosphate it I have a faucet bowl that God God knows how many rounds are there and I shoot 800 rounds in the range today easy and that’s not a lot for me to add that up end-of-the-year that’s still a decent amount of rounds but sure with the company where if the carriers work it could be I think there’s specs on it that they’re just way too tight and I got one that was too fucked up it literally doesn’t open when what I learned in Boot Camp on the island was yes I can do you with your carrier and your boat should unlock and you could try to pretend to throw this fucker and like pull your shoulder out your socket and it does not want to move and you get out of fucking greased up like a fucking porn stars vag it had no joy
