80% 10/22 Receiver - What Not To Do
 

Don't try to bore the barrel hole with your drill press. Not unless you have a much better press than I do and a good X-Y table or vise. Edit - Or a mill, which is what the manufacturer recommends.

All the other holes came out okay, guess it made me overconfident. <Scraps part, shrugs and chalks it up as a learning experience>

Where did you get an 80% 10-22 from ?

how bad is it? probably could be bored oversized, sleeved, and then bored to final size.

So what happened?
Off center?
Angled?
Any way to add some weld-in filler and try again?

Off center and angled. It could probably be bored and sleeved, but then there'd be potential headspace issues and the time/money wouldn't be worth it. Better to start over when I can get access to a mill for that single operation.

The receiver came from the Z ME FLY group buy. It's good gear with the right operator (obviously not me) to finish it. Think I'll deal with the AR 80%'s I have on hand before I try a 10/22 again.

Grumpy,

You want to send that little problem child my way? I can bore and sleeve.

Can't do that... unless you have an FFL. Once the first hole was drilled, it became a firearm. It's locked up in the safe until I can figure out what to do with it. Luckily, it doesn't take up much space.

You can buy them from http://ruger1022receiver.com/

What was your process? Like, did you step up the drill bit sizes to ensure a good bore? Or did you just grab the 11/16ths bit and try to drill it with one swoop?

No, I'm not quite that stupid... I stepped up in stages. Keeping the 11/16th centered for the final bore was too difficult with the equipment on hand. I'm pretty sure that none of the smaller drills wandered.

FUL asked where I got it from. Reading fail.

Can't you do paperwork saying its been destroyed then sell it as scrap?

Nope... You can't declare it as scrap and sell it as is.
It has to be destroyed/demilled as per BATFE guidelines like how other parts kits with torched receivers enter the USA.

Yep, torch cut in at least 2 places, displacing at least 1/4" of material with each cut.


You can send it to me, I'm working for an FFL and I can always use the experiance.

That reciever's not scrap just yet...

Bore the hole slightly oversized, just enough to make it round and straight.
Single point thread it on a lathe.
Take the barrel and cut the back end off it.
Turn/thread a new shank to fit the reciever.
After the barrel is torqued into the reciever, mark the extractor location, remove barrel and make that cut as well as the final chambering and feedramp blending.

No, not reading fail. I was giving more options after you said where you got yours from. Since yours was a group buy I'm assuming its over... the link I posted is still valid last time I checked. The guy sounds like he wants one, I'm giving him a location that currently can fill his possible need.

Comprehension fail.

Randall, I'll PM you. Hopefully the save will be economically viable.

obviously you'd need to start with a long enough barrel to do this and still stay over 16" with the finished barrel.

so don't start with a 16.25" carbine barrel.

Darn right, unless a pistol build were contemplated.

I'm beginning to rethink your original suggestion of boring and sleeving. It looks like there might be enough of the face left for the barrel shoulder to index on. It'll have to wait until I have access to better equipment to make a trued bore, then we'll see.

As I told Randall, if all else fails, I can mount it on a wall plaque with a caption that reads, "PATIENCE!" :kest:

@Grumpyoldretiredcop

I recently bought the Razor 80% receiver, jig, and drillbits from http://ruger1022receiver.com/ and it came with a decent set of instructions.

I was surprised when I read in the instructions that drilling the barrel hole with the included 11/16 bit was NOT recommended unless you have no other option. Instead, it recommends using a milling machine with a boring tool OR a reamer to bring it up to 0.6875. Once I get around to starting mine, I'll either put a video up or a set of photos/instructions to help others out with the process.

I hope you're able to salvage your receiver!

Whoops. Forgot that once you drill at all it's not an 80% any more.

Go make friends with a machinist who can help you out. I'm a little far for you or I'd do you a favor.

Hope you get it fixed.

I guess if you had a lot of time to spare. You could build a portable line boring setup, Drill a hole throw the back of the receiver and slowly bore it out. then use a commercially available bushing to sleeve it. possibly could be done with only a drill press and a little time.

I've finished 2 10/22 80% receivers and drill a hole throw the back for ease of cleaning, so adding a hole in the back may not be a bad idea.

here's mine

Can someone post pictures of the inside of a cnc 80% receiver. I want to see the inside where the barrel sticks through.

Thanks
