View Full Version : Strange observation

So today I go to pick up a upper receiver to complete a build, and the shop had a BCM for $120 and a Aero for $100. So I immediately think to myself there's no way I'm going to buy a Aero part. I bend down and look at the BCM and glance at the Aero. I notice what appears to be the exact same forge markings. I ask to see the both and confirm the are from the same forge. Now I never would have expected that. I actually bought the Aero one for $20 less. As much as I wanted to talk myself into the BCM one I couldn't. Anybody else notice this before?

Never noticed it but I'm not surprised as there is a finite amount for forges in the U.S.
What happens after the forge is far more important to me.

Matt,
If you are looking at the forge mark, you are missing that only says what foundry/ forging it came from. That has nothing to do with the quality, not even a tiny little bit. The forging has nothing to do with the machine work, finishing, QC, or quality.
^^^what stick said.
I'd have gone with the BCM personally, ESPECIALLY for a $20 bill. That's not a comment against Aero, but rather one FOR Bravo Co.

I've used multiple Aero uppers and never had any issues with them. I've heard lots of good things about BCM too though.

Lots of places buy raw forgings and machine them out themselves, like BCM
If i were in your shoes, i would've went with the BCM.

After having both uppers for builds, I've noticed the past 3 BCM uppers all displayed tighter fit for the barrel extension than the Aero upper. Supposedly this increases accuracy but I've never really tested the claim.

Higher tolerances and QC end up costing a little more. That being said, that isn't making Aero products bad, but little details like that are important to many people.

Aero uppers are of excellent quality, fit, and finish. I have had excellent results with them over the years. I would have done the same as you and put the 20 towards something else.
Thank you. Now I don't have to state the obvious.

Not only is the barrel fit tighter, but all BCM uppers to my knowledge are also dry film lubed. Most all commercial ones to include Aero are not. Or at least the ones I have seen.
Aero receivers, both upper and lower, are of excellent quality. The times I used their uppers I had to gently tap the barrel to get it to fully seat because tolerances were extremely tight. Lots of very well known gun guys use their receivers for the platforms of their high end builds so buy and use with confidence.
You did fine OP. I'd have put that $20 to something worth while. Aero receivers are high quality. No need to spend more unless you just have money falling out your ears and want to burn it for no reason.

Yup...to the folks that say because it is the same forge marks, mean it is the same product, I tell them that is the like saying that all hamburgers are the same, because there are only a few meat packers in the country.
And as has been mentioned, the BCM uppers have a tighter fight to barrel intentionally. On the other hand, I have not been able to stock any BCM uppers for quite some time, but I do get some Aeros on a semi regular basis.

glockshooter, you made a good choice. I would have done the same thing. Given the extremely good quality of Aero Precision uppers, why pay $20 more for the big white BCM letters on the BCM upper?

Same here, no brainer. BCM is top shelf machine work & QC
Well well, look who it is.Interesting first post. Care to explain what you're contributing to the discussion?

Must be some "inside joke" ? Maybe they know each other..........

On a side note, the stripped BCM uppers are not marked in white letters like the complete uppers.

Thanks for the replies. I guess I was looking at it to simplisticly.

I've never been able to see an actual difference in the machining. The only forged receivers that I've handled that have a slightly better finish and attention to detail were from Mega Arms and Battle Arms Development. Also whatever Aero uses to finish their receivers seems to hold up better to scratches compared to some other manufacturers. They have a slicker feel to them instead of the scratchy chalk like finish found on some other examples. To be clear I don't have a bad thing to say about BCM though. They put out nothing but high quality components. But I just don't see a difference when it comes to receivers machining or fitment. Maybe I've been lucky but all my Aero Upper receivers have had Excellent tolerances with absolutely no issues.
