anyone have issues with parts breakage? I was cleaning mine and I noticed what looked like a chunk of the chamber broken off.

Will the drum fit a folder when folded?

Sadly no. The drum does fit though.

Yah will need pics to substantiate that.

Anyone having a hard time getting the handguard off? Can’t seem to get her off to get to the gas piston.

On a standard T81, rotate the sight so #2 is facing up. The pull the LHS dial out and rotate forward to #1 position. Rear of Hand Guard will lift up.

Is it true the drums only have 5 slots cut for 5 rounds as opposed to pinned drums that have all the slots cut?

It is true. 2 double slots.

I don't know how to put photos up so I made it my profile picture. For clarification it is a small piece broken off the end of the chamber. Approximately 1/8" missing. The bolt face doesn't mate on the face completely. I have only dumped some 700 rounds through it. Gas setting 2

Is that an lmg? That my friend is a failed heat treat. You can see the grain is quite coarse. If it's an lmg, that needs a warranty repair as we don't know how far into the chamber the heat treat failed. As far as functionality is concerned, the gun will still work as the brass will expand and seal still but now the brass can get caught there. So you might see failure to extract.

Oh wow....

No Bueno.
That's some bad steel in a place that takes ALL the pressure of the cartridge being fired
I'd stop shooting that thing and see about warranty replacement brother.

If by whole section u mean the whole shiny portion in the picture then i got good news for u.... its supposed to look like that. They all have that. I believe its the relief cut for the extractor claw.

 

[WilliamM]

upon closer inspection the Circled part does have the relief cut but the right side is clearly sheared off. But expert opinion is it safe to shoot?

Ull have to upload a more well lit and higher rez photo to get a more solid verdict. I use IMGUR.com to link photos to CGN... dont feel ashamed. Posting personal pics to CGN IS generally a pain in the ass.

Assuming I did this correctly, here is a clearer photo
