Yes, it was perfectly predictable that people would react hyper emotionally like a bunch of women to a discussion about the quality of a tool.

A BCA AR and a Hi-Point 9mm would be a winning combo.

Parts are parts, That’s all snake oil talk:))))

It is predictable and funny.

Both sides are right, and wrong.

Different people, different expectations.
Different requirements/different prejudices.


The only ones wrong are the ones that speak in absolutes.
The big boy will make one that fails,
The cheapies will make some very good, accurate ones. Usually. Maybe.
That, is the difference.

What does drive me nuts is the hidden stuff, and the overlap.
There is so much outsourcing, how can you be sure you Knight's
isn't sharing some parts with a cheapie? Or at least manufacturing?
Or, does it matter?

If a top tier started buying bcg's from BCA, is that ok?
What if they meet or exceed true mil-spec?

Of course they would have to hide it.
Otherwise, the high end buyers would be pissed.

And the low end would be bragging their bolt, made to different specs,
was "The Same parts as the $3k guns".

it's quite possible BCM and BCA could get some parts from the same manufactures.

Those that fail BCM's QC get sent back to the factory, and resold to BCA. That's basically how DPMS started, buying Colts QC rejects.

Thanks. I'll pass that on to my son.

All that is really nothing special, only as it should be.

And what you will get from the top tier companies or if you build yourself & select your own individual parts, as pretty much listed above.

Pretty much all really good component suppliers will state the specs of their components, similar or more or less, as above.

If they don't, you can pretty much be sure that they don't meet those specs..............not always, but since the good ones do, why buy parts that don't call out or give you their specs?

JMHO, YMMV

How many companies actually list the specs on the firing pin retaining pins?

Cotter pin--Ace Hardware.

I'm glad to see we have all came to an agreement

$1200 uppers are great I'm sure, but I'm no "operator" and it will be a cold day in hell before I spend a grand or more on any AR, much less an upper alone. No different than many that won't spend $1500 on a Benelli when I will and have 3 of them.

I said "not always"...................

That's a part that usually doesn't have the spec cited..................even from Colt.

Colt Parts

I believe they were the subject of an immigration raid not long ago? Not the kind of company I'm willing to support with my money.

I know, can't see why it would matter to you that BCA would work for folks. Estrogen high?

Not really sure what an "operator" is, but I'm guessing some kind of "professional soldier" whatever the fu^ck that means.

And I'm guessing that most of their uppers are a little north of $1200.

From what I've heard it was a temp agency that sent illegals with forged documents to work for them and BCA was released of all charges. Just what I've heard...

Who wouldn't want to pay for a gun or parts made by illegal aliens? Sounds pretty solid to me. Lets see if Rick can get them to sponsor the AR and Tactical Rifles forum.

Or by temp agency employees too.......................they gotta be well trained & highly skilled help, too. Hard to make this schitt up.
