Greetings, everyone!

Been an HK fan all my life. Currently have a PTR-91, HK-91, and a C-93 that's been modified.
Introductions aside, this post has to do with my c-93. I took it on trade a while back. The guy it belonged to replaced the BCG (hk), and barrel (RCM).
I shot the rifle again last weekend - shot fine aside from launching brass into the upper atmosphere (but the brass wasn't dinged or damaged, light flute marks).
Anyway - I noticed that ::sigh:: half the barrel retaining pin was gone, cracked off. I was shocked, honestly. I cleaned the rifle, checked the bolt gap and at that point there was barely any
on the (looking down through the magwell) on the left side and none on the right.

I ordered a new barrel pin (new from RTG Parts) and +4 rollers. I'm wondering if I should find someone to repress the barrel / trunion or stick with the scientific method for now and just try
replacing the pin and rollers to see if it irons itself out. Any thoughts would be greatly appreciated!

Regards,
Dan

Welcome to the board .
It's a nice a resourceful place .
I'm sure someone will give you some insight .

Thanks, I sure hope so. Wouldn't want a BCG where my face used to be, or anything like that.

As far as a Re-barrel goes, I'd reach out to Jeff, aka Ghilliebear
Not sure if he's still working on Century guns,
But it's worth an ask. Good luck, & welcome.

Personally I'd have it repressed and pinned. Especially if the gap was in spec when you got it and now has no gap.

I'm not saying that's right or wrong, but that's what I would do.

 

[dan1987432]

thanks for the input guys! re-pressing might be my only way to go.

 

[dan1987432]

Oh and I just re-cleaned the rifle and remeasured the gap. It's at a tight .051mm. Which, yes - is way too low, however it has been shot a lot. So maybe it's just time.

If the new pin pounds in as it should the barrel hasn't shifted and the new rollers might fix the gap.

 

[dan1987432]

I'm hoping that's the case... Not because I'm cheap, or anything - I just want it back in action. :25:

*Update*

Greetings, all

Well I installed the barrel pin and +4 rollers. Didn't seem to change the bolt gap at all. Very strange. It does use an old, surplus HK-33 Bolt, Bolt Carrier and Locking piece (all matching). Perhaps the locking piece needs to be replaced. It's a #8 LP. I just want to exhaust all available options before I start rippin' parts off and repressing 'em. IF i can even find an HK armorer near me here in Ohio.

I sent the rifle off to Fairfax Firearms Repair

I never worked with him, but I've heard good things about what he can do with c93's.

Fingers crossed...

Welcome aboard. Enjoy the fellowship and information.

FINALLY got the rifle back from Fairfax Firearms Repair. Keith did a great job - bolt gap is holding at about .5mm after a couple hundred rounds of 556x45. We'll see if it settles a bit or not! :30:

Glad to hear the issue is resolved. Did FFR re-drill and use a over-sized barrel pin or remove the barrel, rotate and re-press??

Welcome to the forum. Nice looking rifle, glad it's sorted out.

So what did they have to do to get the rifle back in spec?
