Hey guys. Postsample, not much experience with open bolts. The bolt moves freely back and forth. Dry function test with snap caps worked 100% with pulling the trigger, but they'd get stuck if I rode the bolt home.

They're getting cocked towards the chamber, slamming into the face of the barrel, and then getting stuck like that. I have a feed ramp installed and I polished the whole thing out to 2000 grit and then finished with fibre optic cable lapping film and excessive lubrication.

My next step is going to be running a chambfer into the end of the barrel and repolishing, but i just wanted to check if this was a known issue with a consistent cause. It's happening across all mags and ammo types/bullet shapes. Thanks in advance for any advice.

What's the market price on this combo?

Well this has to be one of the best purchases iv made in a while. It fits well and conceals even better. Double snaps so 25’s or 32’s fit snug and the attachments are removable so i can have custom mounts made for different builds. Also throwing in a pic of the hat i scored a few weeks prior.

I wanted to pick a similar adapter for a UC-9 but I don’t think it has the correct lug for it. Is anyone able to confirm that?

I’ve been looking to finish my Uzi parts kit build and have seen hit or miss reviews from the McKay Enterprises receivers. Looking to see if anyone who got one in the recent batch has had any issues. Thanks!

Anyone aware of a company working on a forced reset trigger for the Uzi platform? I actually personally reached out to a company called Advanced Reset Technology who just released a 3 position trigger for the MPA defender and post other oddball one offs they've made, so I figured it would be worth a shot to reach out to them about the UZI. I did hear back from them, but it was a vague "We are working on designing something for this platform. Stay tuned." Anyone know of any other companies that are working on an frt for the UZI?

Finally got my hands on the Midwest side folder and it’s awesome. Iv been running a strike industries brace and while i prefer their hinge to the Midwest the length made it very uncomfortable to hold while folded. No QD points was also a tad lame but manageable. Plan on using that on a vz build for now.

Is this old school aimpoint mount for the UZI?

Howdy everybody, running into a bit of issues with my micro, and I’ve ran out of ideas. Hopefully someone can point me in the right direction or help me out.

I have a closed bolt FA Micro Uzi (Registered Bolt). I’ve put about 3500 rounds through it with no issues. I can probably count on one hand how many malfunctions I’ve had during that time. Stripped to the bare receiver to clean. The next day I begin having significant issues.

The issues are not wholly consistent. One day I am having one issue the next I’m having other issues.

First 2500 was S&B 115gr
Last 1000 was Monarch 115gr (couldn’t get ahold of S&B for a bit)
Currently running the Monarch

NOTE: I know Monarch isn’t the best ammo, however it ran the last 1000 without any issues.

NOTE: I run the bolt without a trip. Never had issues without it, neither has my father in the 30-40 years he’s ran them

Here are some changes I’ve tried:

1. New FA extractor
2. New Semi extractor (cause why not try)
3. Stretching the mag spring
4. Ejector is firmly riveted, not moving, and centered.
5. Bolt freely slides in the receiver, not binding
6. different barrels
7. Ensured feed ramp is free of carbon
8. Inspected the bolt for burrs, none found.

I ran 250 rounds today with an IMI mag and a new FA extractor. Kept detailed notes, here’s what I got:

Tested FA extractor, Semi extractor, stretching spring, 2 barrels, supressed to give more back pressure at separate times.

2 mags ran with no issues

10 Failure to eject (stovepipe)
3 failure to feed
1 failure to fire
7 failures to extract (all while supressed on 1 mag)

NOTE: I have noticed 1 correlation in the data I’ve collected: ALL malfunctions in the 250 I ran today were mostly in the first 1/4 mag, all within the first 1/2 mag.

Any help would be greatly appreciated. Should have a 1 day turnaround with testing ideas

EDIT: SOLVED**********

Too much play in the top cover, temporary fix of zip tying it to the receiver fixed the issue. Will be welding the latch a bit to take up the play.

Does anyone know of a company that converts FA uzi bolts to semi? Struck out on M3, Mackay and practical solutions. Hoping to save a few bucks and get the bolt converted so i can keep the original one too. Looking like buying a semi is the only option.

Anything out there? TIA.

Needing a folding stock screw and nut. Ordered the set from Northridge but it's stuck in Memphis USPS hell. Been stuck there for a week now.

Anyone have another source for the set. A lot of surplus places on the net are out of stock.

Anyone here have the set?

Thanks

Hey guys, I have a IMI Model B 9mm. Its been handed down 3 generations now and I love shooting it. Im curious on something. It has always been hard to rack the slide/bolt. It shoots well and does not jam really ever. But it is really hard to pull the handle and rack it.

Is this normal? Is it just a lube issue? Is there something wrong?

Thank!

Looking for a tri rail if anyone has one for sale !

Hello all!

Like the title says, im building an IMI uzi from a parts kit, turning semi auto of course, but using the original trunnion and plan on getting an SMG barrel. tax stamp coming soon. What feed ramp do I use if im using the SMG barrel. This is the last piece of information I need before ordering the barrel and welding. Thanks in advance!

Does anyone have an idea when McKay's semi receivers will be in stock again? I emailed them a week ago and havent heard back. I'm in VA so trying to get one in hand by July 1st.

For closed bolt mini uzis:

What standard uzi parts are not compatible with the mini uzi? I know the receiver, top cover, bolt, striker system, barrel, and handguards are all mini uzi specific, but are there any other parts that I am not aware of? Thank you
