PPS43 semi build

Sear shelf milled off bolt. Bolt through drilled, recoil rod drilled for firing pin clearance. Made the firing pin out of a drill rod blank. Made firing pin guide bushing from 4340, hardened and pressed it into the bolt face. Now to machine the semi fcg. Essentially a scaled up VZ61 fcg.

Yet another Sten MK3 post.

8 Upvotes

I was wondering if I could cut my receiver tube an inch shorter. I know they have 1" shortened receiver tubes for the MK2, so was curious if I could do the same with an MK3... Could it be cut more than 1", possibly 2"?

Lastly I had ordered a receiver tube blank from sten parts . Com and didn't realize that it was a chromoly tube... It is nice and thin and I do like the fact that it is laser etched for where you need to cut out, but I have never tried welding chromoly especially to mild stell which the parts kit is all made from. Does anyone know where I could find a mild steel tube that's thin wall like the chromoly tube? I've looked everywhere and can't seem to find something within the specs of the original tube.

Are the magazines reliable? I have a few that are blocked to 10rds and was wondering if they are going to give me issues constantly....

Lastly, this is just out of curiosity and am asking for sh*TS and giggles, but I noticed that they have brass bolts which speed up the cyclic rate on the fa version. Is there any other way to speed up the cyclic rate? I'm wanting to shorten the tube for aesthetics and am going to be building a sa, but hypothetically would that raise the cyclic rate? Would a neoprene buffer installed behind the spring help raise the cyclic rate or would it just cause it to jamb more?

Weatherby 307

1 Upvotes

Thinking about grabbing a 307 in 22 creed and throwing it in an ultradyne chassis, but never been around a weatherby. Curious what to expect out of the action and accuracy. Quality? Or not so much.

This will be a squeeze a few off maybe out to 500yds for fun. Mainly a slap a thermal on it and chase dogs. I have some custom actions but going down the “cheaper” side this time. Thanks guys

Cerakote sources?

Thumbnail

10 Upvotes

I'm looking for sources of decent cerakote and powder coat for quantities around 16oz or less. My wife bought me some online with a kit which has been great. But the powder coat is not hard enough with some brands and seems too soft and fairly easily scratched. Or possibly I'm doing something wrong? Prep is washing down with parts cleaner and bead blasting. These packs say to bake 10min at 400. Photos of what I've played around with so far.

Hard to find AN-M2 kits, so why not do it with a 1919. I will be putting the build up on my YouTube channel.

Ruger Mini 14 Enhanced Ranch Carbine

*First picture is the finished stock project fully assembled, NOT a rendering or photoshopped concept design*

This one took about a month of various design iterations and searching for parts that would all work well together and truly enhance the Ranch Rifle to be a more modular platform. The actual modification of the stock took about 6 hours of measuring, sawing, sanding, and chiseling to fit perfectly with the grip adapter.

- ERGO Mossberg 500 AR grip and buffer tube adapter

- Driven Arms Co VCG

- Magpul MOE TR

- Monstrum red dot and rail

Yet to do:

- drill stock fore end to accept short picatinny rails on sides and bottom to mount grip stop and flashlight

- Accuracy systems adjustable gas block

- Barrel shortened and threaded

- Quiet can

M70AB Build Questions

0 Upvotes

Hey there!

I've been wandering around the internet and was pretty sure my next build would be a CETME/G3, but I saw Apex has cheap M70AB parts kits.

I know the front stub can be pretty readily converted to a trunnion for a stamped receiver build, but does anyone have any experience with the rear? Guessing from photos, it looks a little thin to peel a millimeter off each side.

It would just be a screw build (spare me, fanatics; I know) and strictly a functional rifle build with no qualms about anything looking wonky if it works well. I'm looking at the M92 flat from AK Builder, and the big question in my head is if I fudge the dimensions to fold it a little wide at the rear, will I have a gap with the dust cover? Or will there be any other unforseeen BS I can't think of? Like I think the BCG has large enough tolerances to not care, and I can cut the notch for the top rails wherever I want. I know I could just dish out for the actual m70AB1 rear trunnion, but they're oddly expensive--I'm guessing because a lot of, or at least enough (25, lol) people have this idea.

I'm sure I could figure it out, but I'd like some input from anyone with any knowledge before I go on one of my damn fool crusades again. The CETME might honestly be a better fit for me, but cheap ammo and a profile that doesn't scream firearm when you're walking in and out of an apartment building is pretty damn appealing. Edit to clarify: no, I'm not a hit man, I just get some looks when I walk out to do some completely legal and innocuous shooting when I'm pretty obviously carrying a rifle case. That's all.

Let me know what you think! Thanks in advance! Everything is appreciated.

Receivers bent, carrier drops clean, trigger packs cut and clipped.

Still have to clear the tube, reweld, and parkerize.

Order of assembly and SBRs

5 Upvotes

I was watching an AK build video and a question came to me. Since an AK (and I'm sure many other firearms) can be fired without having a stock attached, must you build them from kits (or in the factory) in such an order that you do not accidentally create a SBR, or is their some legal grace given to firearms considered to be in assembly. I am not American so apologies if this is obvious to those more familiar with your laws.

Homemade Single Shot 22LR

Post image
194 Upvotes

I just finished my single shot target pistol about a month ago. Yeah, it’s ugly, but I built it from the ground up and I’m proud of it. I manufactured everything from raw stock with the exception of the springs. Barrel machined from 4140 steel. It was drilled, reamed, rifles and chambered on my lathe. Frame is 3D printed from PETG. Bolt body, firing pin, sear and locking pins are all machined from 4140 steel. The rest was made from 1018 mild steel.

Considering this was my first homemade barrel (and first homemade gun, in general), it came out exceptionally well and is very accurate. The picture doesn’t show it, but I’ve attached a picatinny rail to the top of the receiver and put a red dot on it. It’s currently one of my favorite guns to shoot. I’ve put approximately 1500 rounds through it so far. I have a list of improvements I want to eventually make to it, but for now it works.

UPDATE:

Since some of you have asked for pictures of the internal components: https://imgur.com/a/jTyaGkb

I’ve numbers the components. Feel free to ask questions.

Where to get Sten Mk 2 Plunger

6 Upvotes

I just bought a mk 3 kit and have all parts needed to make a frankenSten mk 2 build except for the magwell plunger. I can’t find any in stock except the keystone arms ones which are upcharged by a lot. Where/how did any other Sten builders here get the part, and would anyone happen to have a spare one lying around?

Problem with 3d build

I don’t know what’s happening with my trigger it seems to not be resetting and it’s pretty hard to pull back and won’t do it when the slide is just sitting there normally. If anyone could help me figure out what my problem is that would be great. Also seems like my firing pin wasn’t really working really great prior to this.
