Century C93...Whats it gonna cost to fix?

[6500rpm2]

One quick question-does anyone know who the barrel manufacturer is? If it's a quality barrel to start with, but slightly undersized from Century polishing, couldn't the barrel be knurled and re-pressed? Is it beyond that, or are the barrels pretty much junk compared to what's available as another U.S. replacement?

Thanks for the welcome, yeah I figure if the furniture is bad I will replace it with some stuff from HKparts.net or whichever place has good prices. I got 9 days left until I get to see her, despite the fact that I could have got a vector for $500 more dollarst, I'm still happy its just gonna be a range gun for fun, I have my P220 and my mossy 590A1 for those pesky cat burglers and murderers.

I have been reading over the 922 stuff and it seems like theres at least an american made part for every german made part online so you can keep up to code.

The reason I went cheap on this gun is because I am saving for an HK USC in gray, I love that gun, and I love .45 ACP. They always have them out here in CA at gun shows with radlock bullet buttons on them and are usually not marked up much at all.

Anyway I got sidetracked, I can't wait to see how superbee's bolt gap holds maybe if he has good luck it will rub off on me, if not thanks for letting me know I can find someone to fix it here thats a big relief. So far atlanticfirearms.com has been quick with customer service replies and fixed a shipping problem almost instantly after the gun had already gone out so I at least hope they give the guns a good looks over before they send them out or, fingers crossed, test fire them.

I was wondering the same thing, also how can I tell if my barrel is undersized from over polishing or the other issues that people have had with their barrels, this is my first *cough* hk *cough*, so I don't know too much about the schematics of it. I have been trying to find as much info online as I can but figured I would also ask. I've only really worked on AR's sks's and AK's (when it comes to semi-auto rifles)

Hello all, I wanted to ask 6500rpm what he used to press his barrel in to .020? I might be interested in doing the same job on my rifle. I bought mine in September and measured my gap at .011. I know it will shrink after I run some rounds through it and want to fix it on the cheap considering I only paid $486.00 for the thing.

After removing the barrel pin I cleaned up the hole w/a needle file and some emory cloth strips to help prevent any gauling. I have a set of numbered drill bits and inserted one the was slightly smaller then the pin hole as a stop. Used some scrap tube to support the trunion in my 12t H press and did the stacked penny trick on the crown and pressed. Removed, reassembled gun, measured gap, repeat........several times. Actually thats the short version. 1st time the gap was around .024 and had to use a aluminum tool I fabricated for AK barrel pressing to press back out. Final fine tweeking was done hoosier style with a stack of pennies on the crown and mild tapping w/ a 20 oz hammer to get it right at .020". Bought some reamers from Enco and associated slightly larger bright HSS drill bits to make a new pin for a good press fit in the hole. Lots of measuring, assembly/disassembly but I think it paid off. Between my job as a Tech (read mechanic) and building AK's, tools are kind of my thing but this is my 1st trip with the HK platform.

The barrel have been undersize too the point knurling will not help and install a oversizing barrel pin is not the fix..
the barrels are junk .look at the frount sight it's is welded on not good.. get rcm barrel and frount sight fix it right..and it will be a good gun..

My concern with 6500rpm's fix is he has addressed the gap problem, but not the cause of why it shrinks.

I'll be very interested once he gets 300-500 rounds through the gun to see what kind of change in gap he sees. If an oversize pin can fix the problem that would be great. However knowing how the barrel is supposed to be installed I have a hard time believing the pin alone can provide enough holding force to keep everything in place.

I'll try to run up another couple hundred rounds this weekend and get it to at least 500. My concern is that Ghilliebear is well versed on this platform and he"s posted that he's fixed 70+ C93's and most or all required barrel replacement. I felt pretty good about my press fit to the trunion based on how much pressure it took with the press to get it to release and start to move. From whats been posted on the board, there has been two, or possibly three subcontractors who built this gun for Century. My assumption is that Ghilliebear has most likely worked on all. I can't see all these sub contractors jacking up the barrel doing the same thing which leads me to think the barrel diameter is crap from the start since they're probably supplied with the same parts to build with (exception being the change in receivers used from SW). It's very well possible that all these barrel"s are out of spec. I'll post up in this thread as round count gets to 500+.

As a reference, I know two things for sure-after setting my gap the hole was reamed over-sized perfectly round (trunion & Barrel assembled), and that the barrel pin used was .0025" larger than the reamed hole diameter and was made from a shank of a high speed bright drill bit shank (which I assume should be plenty hard?). Based on these two things, "IF" I have a good press fit between the barrel and trunion, "What" is the normal expected, or max increase in bolt gap that I should have from the zero round measure to the 500-1000 rounds shot measurement? Right now at a bit over 300 rounds I'm at .0015-.002" growth.

I was under the impression they were using Rim Country nitrided barrels. But... I just got my replacement C93 from Cent's Cust Svc - it has the typical Cent white tag on the tigger guard that says something about "Spec Weap Barrel". Have no idea why the prior gun did not. In retrospect, from pics I've seen of the new, USA-made "HK33" bbls - they do not seem to have the same profile or the little "ring" ahead of the front sight tower.

As an aside, this replacement C93 has nicer (but still painted) original furniture, slightly nicer welds, and truer "alignments" than the one I sent for repairs. Unlike the other, this one has the S/N on the side of the magwell, yet is still black-parked. Has all matching "BCG" just as the other. Out of box bolt-gap is .015. I'm still de-grunging it, who knows what the gap will be after the cleaning, or after 400rds. Will post back for sure.
