Uzi FA bolt to a SA bolt conversion question

[Ben Walker]

I have done a search . Maybe I just did not word it correctly .As I am sure it has been addressed before.
I need a SA bolt and I am cheap .
What I need to know is do I have to machine off the lower lip of the bolt face . I have been reading and it seems if it was there . Then it would feed much better .

I'am thinking about putting the bolt in the oven on the self cleaning cycle . By doing this it should change the RC for a tad bit easier machining.
Or by leaving it on the bolt face does it make it a FA bolt still.

TIA

if you're cheap, it seems the easiest way to aquire one is to buy one. From what I've read and seen there's a lot of machining to do to that bolt. If you don't have the right equipment available you may as well forget it. Also, It's not legal to leave the lower lip on bolt face. Wish I could find it for you, the info your asking about is on here somewhere.

I have the tools and time to do the work myself . So I will just need to mill off the lower lip then. Well the wife needs to clean the oven this week .

If you take a FA open bolt and do nothing other than mill off the lower lip, it's still an open bolt, which is not legal to run on your semi-auto UZI. Plus it won't even fit in the gun because a semi-auto UZI has to have a bolt blocking bar. If you mill a slot in your FA bolt to clear the blocking bar, then you've created an unregistered machine gun. Your only legal choice is to completely convert the FA bolt into a valid semi-auto closed bolt. D&D Sales and other people have done those types of conversions.

You seem unusually interested in semi-auto open bolts. It's starting to sound fishy.

No not open bolt . convert a open bolt to semi auto closed bolt like others do just not pay over 200 for one . . I ve looked at my 320 bolt and my mini bolt . And it does not look to hard to convert one to semiauto .
If you look at my post it reads FA bolt to SA bolt .
I just need to know if I have to machine off the lip as well as all the other machine (I know all about the denail bar etc ) operations for converting a fa bolt to sa bolt.
And yes I know to drill for firing pin first as makes bolt unusable .
And no fish here . I only eat chicken .

Curious to know where you get this from, that it is illegal to have a lower lip on a semi bolt. Please link to factual law for this. As best as I can tell, there is nothing illegal about having, a semiauto UZI, with a semiauto bolt, that has a feed lip on it. If the bolt fires from the closed position, in semiauto only, and is incapable of creating full auto fire, where is the violation of the law exactly? If the OP had drilled the bolt for a firing pin, thereby removing the fixed firing pin, is the bolt now, not capable of slam firing for full auto functionality?

Not sure of any law that is why I was asking . I have a 320 a mini along with a micro bolt . And all three do not have the lip.
If I do not have to remove it ( my 320 has had some failure to feed ) then I will not . I have been planning on selling the 320 and building one for a truck gun . Have already welded a extension to a barrel along with turned it. then turned the chamber end to work with a ringed feed ramp.
I figure it will not be to much trouble to build a striker assembly as well as the bolt conversion. A friend's wife has a kiln to use for heat treating the bolt after drilling and machining work is completed .

Ben, my inquiry about where in the law it ever stated that feed lips were illegal on a semi bolt was aimed at the other poster, Brian S. I already knew that ATF has never held feed lips to be a problem, as long as the bolt will not allow full auto fire.

To me, since the feed lips were originally there to help with feeding the rounds from the mag into the barrel, I'd personally leave them, but thats just my personal opinion. The ATF letter you found clarifies exactly that stance, feed lips are fine.
