I have a CMMG BCG, I bought my complete CMMG upper used here on Calguns, it is the 16" WASP model. I've contacted CMMG tech support via e-mail and they said that their BCG's are chrome lined and are properly staked, when I take apart my BCG and look inside the carrier where the bolt goes into it just looks more of the same as the carrier, but near the end of the hole there seems be like a burnt ring mark and after that it is a bit shiny. I am not sure whether that particular part is shiny because the bolt as been riding back and forth and shaved off metal or if it's indeed chrome lined.

Sorry I don't have a camera good enough to take pictures and show you all, I hope I was able to articulate well enough for some of you to understand what I'm asking!

Also! please post pictures showing what chrome line BCG's look like on the inside!

Edit: Took some camera photos

Note: This BCG has approximately 2,000 rounds through it, the photos were taken after a cleaning and lube.

Why don't you send CMMG a pic? They might not appreciate a BCG being sold as theirs if it's not.

Maybe you got scammed. Someone took the nice chrome lined BCG out, replaced it with a regular BCG then sold you the "complete CMMG upper" minus the nice CMMG BCG.

Perhaps, I truly hope that wasn't the case. The BCG I have does not have any markings or anything either.

If look at pics (google for them) of chrome lined BCG, I can't see any shiny bits, maybe just the angles of the pictures. Maybe you DO have a chrome lined BCG.

I'm unable to find pictures :(

P.S, I added some pictures.

cleaning it and then taking some better pictures would go along way.

+1

I would not buy anything from someone that wasn't an actual Vendor or has a selling record on Calguns. Someone with 5 posts with one being the actual post and 4 BTT's I wouldn't trust.

Not saying this is what happened to you but I've never heard of Calgunners scamming people in the year I've been a member until this and last month. Hopefully its just carbon build up put a wet bronze brush down there.

I don't know if CMMG BCG's are fully chrome lined so it might be a completely different bolt especially if the gas key is not staked.

The guy I bought it from, I believe to be an upstanding guy and wouldn't pull such a stunt to be honest. Then again, you never know! I wish I was able to take better photos, but this is as good as it gets :(

How do you know whether it's staked or not?

I believe you CAN take better pics. Some things in the pics are in focus, but not the BCG! Maybe lay them down then make sure the focussing square (or whatever) in your camera is on the BCG.

But that's irrelecvant to your question I think.

So, I sent an e-mail earlier to CMMG Inc's tech support with the photos posted above and asked if it was an authentic CMMG BCG and if it's chrome lined and all they replied was, "Looks good to me." :hammer:

So what you do guys think? is this BCG chrome lined and is it 'properly' staked?

CMMG has outstanding customer service. Honestly take better-more detailed photos and email them to CMMG. They'd be able to tell you within a short amount of time if you've been swindled or if in fact it's their product.

It looks staked but I can't tell since your camera obviously doesn't have a macro lens. CL one can only guess get out some cleaning agents dangit.

Appears to be a standard bolt and carrier........Not that there's anything wrong with that.

Staking looks a bit perfunctory but probably is fine.

Yes, it does look like its chrome lined and staked, not sure though if the staking was properly done.

Here's my chrome lined and staked BCG, its not CMMG though

Aw, thank you very much. Unfortunately I don't have an actual dedicated camera, and my phone camera's feature doesn't include a macro setting; those photos were the best I can do.

I am believing that my BCG is actually chrome-lined though, it looks like your BCG as a matter of fact, but yours is a bit more shiny, but I think is because you have more lube on yours.

use the close shot setting on your camera

OR


MOVE YOUR LENS FARTHER AWAY FROM THE OBJECTIVE SO IT'S IN FOCUS

please note in all of your pictures that the background is nice and clear while the foreground is fuzzy and out of focus. We can't tell if the blurr in photo's 1-4 are chrome lined.

Yeah. You know, I'm over it, these are the best pictures I can get with my camera phone, with any other angle the white balance and lighting would be so screwed up that the photos would be too dim to see the BCG. I would not intentionally post out of focus photos, especially if I am asking for help and/or advice. This is just what I have to work with.

Sure the folks who are offended by the picture quality wouldn't have to believe me that I cannot do any better with the photos, and I respect that. To the others that have work with what I can give, given my current resources, have my appreciation and thanks for your efforts.

And yes, through some research and asking questions to CMMG in the regards if my BCG is authentic and chrome-lined, I tend to now believe it is indeed authentic and chrome lined.

Once again, thanks.

mrvash,

My BCG from my CMMG looks the same as yours. Like the others have said I'd clean it and look more carefully inside as you should see the chroming inside. If not it's no big deal anyway cuz unless you live in a humid climate corrosion should not be an issue. If it does turn out that it's not chromed you can always have it hard chromed by your local smith.

The BCG in question is in fact chrome lined and properly staked with the correct tool.

It's clearly chrome lined. That's what the lighter color "ring" is around the hole.
