My gunsmith friend is back in town for a bit and I want him to make me a stripper clip guide for my Mini 14. He's confident he can do it, but would anyone happen to have dimensions for one? I know there was a company that made them in the 80's but there really hard to find now and I figured I'd give him something to do while he's here for a few weeks before moving for a job.

Last I read 3rd packages showed up but minus the dust bolt carrier group and bolt only the dust cover and some misc part. He will have to refer to some technical drawing and modify a AK-74 bolt carrier to make it work.

See that weird stubby bolt carrier

Here is the kicker, AK-74 bolt works flawlessly with the 9x18 as seen here. 9x19 is actually loose in the bolt but 9x18 is snug like 5.45x39 is seated in it.
>> No. 3361 ID: 72eee7
>>3359
9x19 has a 9.96mm rim and a 1.27mm thick rim.
9x18 has a 9.95mm rim and a 1.25mm thick rim.
5.45 has a 10mm rim and a 1.5mm thick rim.

So yeah, it works, but that rim thickness difference is pretty significant and will need some rework of the extractor and probably the bolt face depth I guess, not sure why 9x19 would seem looser though.

What kind of punch should I get to stake the gas key? Or would I be better off buying the tool to stake it. Don't really feel like spending $65 on the tool.

Also can this same punch use to take the end plate for the castle nut?

Threads really like to go for walks when they're put in multiple hot to cold cycles, while being tapped, hit, or otherwise subjected to concussive impacts. Heating, cooling, and hitting is pretty much one of the best ways of unscrewing something that's screwed in tight, and that's pretty much what's going on inside a gun.

Having your gas key bolts lollygagging about isn't conductive to proper AR-15 functions.

So they get staked.

Some people even go as far as staking the end plate to castle nut so it doesn't walk out also
>> No. 3340 ID: 144d78
>even go as far
I wouldn't say it's a strange thing to do, that's what the cuts in the castle nut are for, it was designed to be staked as well.
>> No. 3341 ID: da3b72
so what happens when you want to disassmble these parts that get staked?

They just take some extra force to unscrew.

If and when the importer finally gets off his ass I'm getting pic related. It's my first firearm and as such I've had to buy a lot of maintenance stuff. In doing so I got a bit lost in the vast amount of oils, lubes, types of grease, barrel cleaners, carbon removers and other fluids.

What do you operators prefer to use to clean your firearms. Especially your .22 pistols.

Yeah, it's pretty obvious, but you said it was your first firearm. And what the hell is wrong with a heavy, 6 shot, .22lr for inna woods?
>> No. 3287 ID: f213c3
I spent some time yesterday wiping away the crud from Sunday and Tuesday and noticed that my cleaning rod can only be used from the muzzle. There is a piece below the sight that blocks access to the chamber from the rear. There is a hole in this piece, but it is about 4.5mm. Unfortunately my cleaning rod isn't 4.5mm in diameter. So either I clean from the muzzle or I order a .17 caliber cleaning rod and an adapter to thread the .22 jag on the .17 rod. Bit of a bummer.



>>3286
>but you said it was your first firearm

Yep, but there will be no inna woods shooting with any firearm I'll own. I'd have to get a hunting license if I want to discharge a firearm anywhere other than a range. That's much easier said than done.

I thought about it. My grandfather was a hunter. It is just really difficult to get access to a proper hunting location here. I think I'll stick to killing paper. Maybe try some field target.

For bore:
Gunslick foaming bore cleaner for 30-60 min, followed up with bore snake 2-3 times. If the bore snake gets stuck on the foam, make a pass with a rod, then try again. Dry patch until almost clear. Repeat entire process until satisfied. Run a hoppes oil patch through.

For guns that haven't been cleaned in a while, leave the cleaner in overnight once or twice.

Action:
Ultra sonic cleaner with hot water, dish soap, a few generous squirts of iso alcohol, and ultra sonic solution. Run a while, then remove part and inspect for hard buildup. Remove with dental pick and put back in ultra sonic cleaner. When parts are clean, remove, immediately dry, and give thin coat of hoppes oil. If the part has a surface i can't dry off, like a firing pin channel on a bolt or something, ill trade the ultra-sonic for hoppes 9 instead.
TW25B used sparingly on slide/bolt rails.

Exterior metal:
Hoppes oil to clean and protectant on parkerization. Renaissance wax on bluing/in the white.

Wood: Wipedown with lightly oiled rag. BLO occassionally on guns that are finished with it.

So I bought one of Ares Armor's comp which they made in responds to SIG's lawsuit with ATF regarding MPX's perma attached comp.

>Yup, centerfire rifle suppressors don't need to be serviced, all of the current best rifle suppressor designs are un-serviceable.

But surely you would need to clean out excess buildup of residue, what would you do just fill it with solvent and slosh it around?
>> No. 3311 ID: f9a97c
>>3306
Not even that. Got some ideas in a few moments, that don't involve welding, and leave the nubs intact.

Not that the design would make a very good/efficient inner for a can, but I already have a couple of ideas for fabbing a can around that thing.

Debris build-up is pretty much non-existent in high-pressure centerfire rifle suppressors. Rifle cans are almost self-cleaning; the crazy concussive force and heat generated within a rifle suppressor when firing keep any noticeable amount of debris from forming on the baffles. All of the internal parts will form a layer of carbon, but chunks of carbon end up breaking off during firing and exit the end of the suppressor.

The muzzle pressure of cartridges like 9mm, .45, .22, and even cartridges like subsonic .300 BLK is not great enough to concuss the building carbon off the walls of the suppressor, so they need to be serviceable (especially .22 and .45 cans).

I permanently attached one of my suppressors to a 10.5" barrel AR, and I guess I have about a thousand rounds through it with no problems so far. I built the suppressor to be serviceable, but haven't had the need to tear down ever since the testing phase ended.

I'm still curious to hear your ideas.
>> No. 3314 ID: f9a97c
>>3313
Think plumbing repair. Not going to go too in depth, but imagine what you'd use to quickly fix a length of pipe with a freeze split.

The other is using the nubs for aligning an inner sleeve then an outer tube with reduced ends.

Again, not going to go too far in depth but should not be too hard for an enterprising experimenter to figure out.

I got the new SBX brace because IMO it's slicker and "prettier" than the SB15 that's why I upgraded. Hopefully this will answer some of the questions any has about the SB15, SB47 and SBX

Some of us live in non fun allowed states.
The one where I live is one of them.
I could have all the $$ I wanted to spend on SBR or those other fun things, but can't have 'em here.

So there kind of is a reason some get them.
I got mine bc I plan on 458socom, and it will probably help for un-supported shooting.

  What options exist for cutting rifling for the home gun builder?

The embedded video is the closets I've seen to plausible system at home, though a bit tedious. It seems the spiritual successor to order methods as seen in the Gunsmith of Williamsburg

Kossel Clear is up and running. Stepper motors are all over the place when the 're hot though, stepper drivers need adjusting I guess. Multimeter and trimming tools are in the mail. Also, i severely underestimated the amount of money i'd have to spend on random tools and such for this thing.

Well, I joined the 3D printer owners fraternity after a couple of years of casual interest. I got a used perfectly well tuned and barely broken-in ORD Bot Hadron with EZ Struder, Mk V J Head and bucket full of filament and spare parts off of craigslist for, get this, $500. The guy was a retired computer coder and lived in the nicest neighborhood I'd ever seen but he and his wife were packing up to move to a smaller house since the kids were moved out. He just wanted it gone even at a loss. I lucked out on the deal.

I've had a couple of spectacular failures this past week but right now I've got it perfectly tuned for PLA but will be building an insulated and ventilated cabinet before switching to ABS this week. Many pictures to follow in the coming days.

Closer detail of the forend itself. The ergonomics are better than the original, it feels sturdier, I feel that I grip it more positively and it has slots for accessory rails. Since I plan on getting a light for this forend I bought the basic $10 rail in advance so I wouldn't need to install it later.
