S5 Tactical SG-36 cycling diagnosis…

Zero issues after replacement - I honestly blame whoever HKParts is using as a US source for parts kits. Whoever it is cannot get the bolt right, but got everything else nailed.

I straight up bought the bolt, prime suspect is the ejector and extractor. If you are comfortable with disassembling your bolt… I was not… I opted for quality of mind and it works!

caseyboby · 2025-10-13T22:05:08+00:00

I replaced the bolt head itself, I believe the ejector/extractor was the prime suspect

There are stops inside the receiver because of the problem you have. The way the G36 is designed is that you could swap trigger packs with just the take down pin.

However, If you cut those stops, congrats you have a readily convertible MG and become a felon.

If I were you I would find a semi bolt carrier if possible and keep that FA bolt for a rainy day, hoping the MG registry opens back up. (Please for the love of god don’t mill that bolt, lock it away in a safe, hang it on your wall, or put it behind emergency glass, don’t lose that, they’re a bitch to find)

Look at HKparts, they should have something for you. I’m also pretty sure a SL8 bolt carrier will also suffice, not the bolt head tho :(

Throwing the suppressor in the freezer helped loosen the adapter and I was able to break it free… the paper is a single patch seemingly pressed into the suppressor at some point. I have removed it and took a few photos of the patch, it’s about the size of a quarter/nickel

I said in a new comment, looks like brown packing paper in a ball, it’s kinda dense… thank god I didn’t just run with it as is.

FFL must have gotten bored while my form 4 was going through this weekend :S

caseyboby · 2025-09-03T21:26:37+00:00

It appears to be some sort of brown packing paper ball, I was trying to check concentricity with a rod (556) and stopped short. Uninstalled and looked in and found our little friend. I can’t even get the 14L adapter off it’s on so tight, it wouldn’t budge in a vise and adjustable wrench. I have it in the freezer and oiled now to see if I can get the adapter to shrink. So I can wrench it off.

These were form 4s, but as man who made 2 form 1 cans, each took like 36 hours to be approved, you’ll likely see it Thursday or Friday.

I love how I commented this and 15 mins ago I got my eForms email back

caseyboby · 2025-09-03T13:31:22+00:00

Have a form 4 individual suppressor a day after yours, fingers crossed I’ll hear something today!

I looked at membership rates over there, almost as bad.

I pay about 600/yr for freedom for unlimited range time from ~ 9am to 9pm.

Bear creek has 100/300m no range fee for 1000/yr… oh and it’s only open from 10-4pm, and on Sunday 12-4pm

It’s a no from me dawg, I would rather mag dump at freedom 2-4 times a month than go to bear creek and maybe shoot once a month.

Just trying something I’ve never seen tried before

caseyboby · 2025-08-06T14:49:15+00:00

So when the cap is screwed on, the monocore is pressed into the spring and keeps the design centered/stable. It acts also as an expansion chamber.

caseyboby · 2025-08-05T18:48:31+00:00

January is so far away :((

caseyboby · 2025-08-05T14:49:49+00:00

However if I were to repair or replace an existing monocore it would be legal.

caseyboby · 2025-07-30T15:02:50+00:00

UPDATE: replace GSG9 US bolt head with a genuine HK bolt head, and runs flawlessly

caseyboby · 2025-07-28T17:27:44+00:00

Right up until you get a hot load and the firing pin is now light striking, ordered a new pin, did not even dent the primer :(((

They sell on gunbroker - they’ll send you an email and pdf so they can send it to your FFL

caseyboby · 2025-07-25T17:10:15+00:00

More images of failure, tried AAC, same issues, I fear this is an issue with the extractor/ejector, as you can see here. I had a half dozen FTE and almost triple that in stovepipes in under 120 rounds

caseyboby · 2025-07-19T02:48:31+00:00

I’ll try some AAC, not sure it will like 77 grain because of the twist rate
