MA Ford video for firearms special form tools

GW Shultz, AB Tools, probably a bunch others make them too..I notice they didn't show anyway, the long keyseat you need to do the internal relief for the charging handle....or the long drills you need to ejection port door cover...

GW Schultz also offers the broaching tool you need for an upper...

As someone who programs with a bunch of these tools, the days of custom tooling are long over...

RTS also.  they made a center drill / cb IIRC tool to reach the bolt catch roll pin hole for the lwr

These tools are maddening at the least. MFG A wants their charging handle keyways cut to whatever standard they use. MFG B comes along and gives slighly different dimensions. MFG C does the same. The tolerances do just barely overlap, but something like the height below the keyway just won't work between one & the other. So we wind up with a bunch of semi-customs in an attempt to keep each customer happy.

And at the end of it....all the internals they are putting in the damn things are interchangeable. Try convincing customer B to change their slot by .003...but no...their "engineer" says it must be this way, cuz it's what they measured on some upper they measured with calipers 8 years ago.

Then what to I know....they are selling them by the thousands, so they are doing something right.

we should invent something to address this. Maybe an industry standard, maybe not ISO. How about a Military Specification? would that work?

That's just crazy talk.

There's an XKCD for everything...

Yes obviously **I** am smarter then them!!!
