80% Jig Question

[Diamondback]

Point is, challenging yourself to be a better machinist. In my case, someday I want to recreate one of the "Gauge Guns" that Colt built to set up new 1911 lines for WWI where each part was +/-0 dimensionally perfect in every way... and trying to get a perfect AR trigger pocket is a first "baby step" toward that kind of precision machining.

It's not about "building the best AR possible," but about developing skills as a machinist rather than just a "hammer, screw and torque" assembler. (Not dismissing AR assemblers--that takes craftsmanship in its own right, but it's a lot faster to learn than getting the results you want out of lathe, mill and drill press.)

Thanks for the feedback everyone. Looks like 5D is the way to go. I'm going to go in on the jig with my neighbor and his brother and crank out a few of my own to put in the safe. I wouldn't mind sending one of them off to SOTAR for a gauge inspection once done just for shits and giggles. Might be an interesting exercise.

"Pride of craftmanship" I doubt there is a single 80% lower machined with a jig that could get through QC of the cheapest lower manufacturer out there. "Desire to flip The Man the finger" It is perfectly legal to manufacture your personal receiver. What are you flipping the finger for?

So are you saying that you have never completed an 80% lover receiver, or that the ones that you have completed were not that great? I'll hang up and listen....

Nope.. Never had the desire to own one.

Then why are you participating in the thread?

OP had a technical question. If you want to discuss the merits of 80% manufacture, and knock folks who engage in it, go start your own thread.

The OP ask for an opinion and I didn't knock anyone. Give one good reason to have one and I'll order it tomorrow.

Yeah uhm no. I didn't ask for anyone's opinion on whether or not I should build an 80% lower. I asked for opinions on which jigs and blanks were best to use from people who had used them. Which you have obviously not. My reasons for wanting to build a few are, quite frankly, none of your business.

An opinion is an opinion. It doesn't matter why you ask for it. I don't really care why you want one. Just tell me why I should want one.

You gave an opinion on a question that no one asked. You've contributed absolutely nothing to this thread. Have a good night.

Evidently you have no answer to my question.
