Oh Krap moments in gunsmithing...

[Bradrock]

Ok I'll admit to being ignorant on smithing, what's this evil extra hole?

I was refering to an AK47 or 74. Semi's have two holes for trigger & hammer axis pins. You can't have the third hole for the full auto axis pin.

I would have given the sear back to the customer so he could sell it & recupe a few dollars

But then, I'm not a pro gunsmith & I understand being very carefull.

Also.....It really does not matter what I think! Heh...Heh)

Well I was going by what I was told by a gun smith that teaches at AGI, So I guess were all ignorant

Nobody claimed you are "Dumb", just misinformed.

My information comes straight from the NFA branch and the director of field operations in the Rocky Mountain Region, Denver office.
I would much rather trust that source.
An instructor at a video school isn't going to be the one prosecuting you.

I would have destroyed the auto sear on the spot.

That was my first thought, but then I got to thinking that it might be ugly if ATF knew that there was a sear in the kit and came looking for it, so I went ahead and called them.

Probably a good call. After dealing wit the ATF when I HAD my FFL, I wouldn't want to deal with them again unless I had to. Mike.

I have found the ATF more than helpfull in most matters, though there info can be some what fizzy in some things best not to do things that may be in question. I am here in california where the members of government belive they are so far above the laws that they force upon use that there former gany members andselling illegal weapons to the FBI but that another story.

Not really a hole as much as a cutout for the auto sear to set in. The sear is the little black piece with the numbers on it. As you can see, it sits in a cutout in the lower receiver which semi-auto receivers don't have. FWIW, modifying a semi-auto lower and installing an unregistered sear will get you a huge (up to $250K) fine and up to 10 yrs. in the graybar hotel...

there is more than that I think. You have to have the pocket machined out properly for the M16 selector and sear. You also DO have to drill the extra hole. There is something called a lightning link that can be droped in a standard AR depending on how the OEM machined the rear shelf. DPMS used to do it and I dont know if they or anyone else still do. AR15.com is the be all end all source for info on this platform. The tech forums and mfg and vendor forums are the best you will find.

Everyone be careful to not get political in this discussion. It is against the site's rules.

Sorry if that is for me. I don't mean to come close to politics on a tech forum. Just trying to provide sources for specific areas of this hobby. I have learned over the years that when you venture into non tech forums you can end up debating things with 12 year old kids who play video games for their source of info. I want to stay fact and real world based. I just ment to provide links to more firearms oriented places that can help with the ATF rulings. The ATF will usually provide the most strict ruling of laws and not include the legal options to the issues.
And I would not go near a full auto set of parts or anything in that arena for any amount. If that's what I want I will pony up the money to go legal. I have done it for a suppressed 22 and a short barrel riffle. I don't want to look over my shoulder for the ATF. Do I think this stuff should be more legal for the law abiding heck yes but Im getting into this hobby for other reasons. Im having a ball just getting my little mill set up and seeing how good I CAN be as a hobby machinist. Which isn't anything special. I want to strive to do work I can be proud of. And an nicely done 80% lower is on the agenda in due time. That will lead to another hobby branch of anodizing.

Gunsmithing forums are the most fertile fora for politics to creep into. No one is ever happy with the laws.

Yeah, it broke my heart when I started grinding the tangs and tails off of the F/A parts, but the guy was set on using the original parts. I wore out the phone calling my ATF investigator asking questions, it would have been MUCH easier building from scratch with new parts.
