CAI C93 , anyone shoot one?

[MrM4]

I am kicking around a C93 from ( I cant believe I'm typing this) CAI.

Just wondering if anyone here had handled one? Im considering using it as a host gun and the price is right.

Ive heard of a few issues with bolt spacing but over all the stuff I have read has been fair on these.

Any input welcome.

Thanks!
matt

My 2 runs fine, very accurate as well. Nicely build and finished, welds are clean. Bolt gap issue is overrated, somebody posted that he checked a real HK93 and it came in at .008. Destroys brass just like the Galil(if you can even find it 20 yards away), that's about the only complaint I have.:boohoo

 

[MrM4]

Does the stell case stuff like wolf and tula work ok?

 

[Surly]

Get one...if there are any problems, we'll get the bugs worked out. I think Century has them listed for ~$500 in their latest flyer.

 

[MrM4]

Yeah they do, I figure it would be a good HOST.

 

[JWH 223]

Is there a good source for mags?

 

[MrM4]

Midway Usa has 40rds for about $20-25 last time I looked 25 rounders can be boutght for under that if you look around alittle.

Shot one about 6 weeks ago. the owner used steel cases and YES it kicked then about 20 feet out.

ran good looked good shot good. BUT it is a CAI so it has that stigma..

I mentioned the bolt space and he said it was a matter of new rollers if it were a problem.

I don't want one as I don't need another 223 but if I needed a host as you say why not?
sure beats 3 K and up for something you are gonna hammer on with a sear or trigger pack.

You Got It! I figure either I can fix find someone who can or send it back for another if it has problems. Some of the best guns Ive bought right was because some else was affraid to "tinker" with it until it worked as it should.

Let's wear the fukr out with a seared trigger pack and send it back for a new one when done.

Hell yeah! It should be here later this week. :allright

I just bought one back in June while I was home on R&R. The fit and finish is much better than what I have seen on the Cetme's they put out. I didn't get to run any ammo through it but I don't see any issues with it up front. My old CAI Cetme ran like a top after I did some tweaking to fix a dented cocking tube. The bolt gap issue has been played way out of proportion. From the research I've done it shows that the gap you see does not equate to the actual head spacing. All the gap is showing is how deep the roller lockers are engaging and is not idicitive of actual head spacing.

I bought a bunch of the Midway Aluminum 40rd mags, good price and they were in very good condtion. I shopped around for some steel 25rd mags but damn people want way too much money for them! I just checked Midways site... they're out of stock.

 

[MrM4]

I was looking at 25 round mags again and rather then buying a lot 3 for $70 it was actually 1 for $70 and 3 on hand OUCH! This will be a bad rifle to own if your a mag whore like me. :confused

Yep that's what I was finding as well. I got mine from Midway for $22.95 each, I should have bought more while they had them in stock. I'm a mag whore too! LOL

 

[az_gun_nut]

This site has some in stock. http://www.hendersondefense.com/store/pc/HK93-40-Round-Magazine-40p78.htm $26 each for the 40rd aluminum units.

That's because a roller-delayed blowback system like these don't actually headspace in the traditional sense. Correct bolt gap is imperative to the proper safety/functioning of such a weapon. If the bolt gap isn't set correctly, the rollers will not engage properly - which can lead to the bolt going out of battery too soon. Worst case is that way too much pressure gets released in a bad way and does nasty things. (Not hugely likely, but still worst case.) The most likely result is that the bolt carrier slams rearward under too much pressure/force and smacks up against the buffer with enough force to jam the rollers out and into the inside of the receiver wall. If that happens often enough it won't be long before the receiver cracks. Here's a photo of my Century CETME that exhibited just such a problem:

You can see the dent in the receiver rail right above the selector lever - there's another one just like it on the other side. The rollers dented the recevier from the inside as a result of the typical drunk monkey gun building that was so common with these CETMEs.

After the propering tinkering this rifle is now running like a top, so I've no reason to expect that a C93 couldn't also be made to run properly... but for anyone who's planning on using one as a host I would seriously recommend making certain the bolt gap is properly set to avoid any sory of badness.

That's a timing issue, not a headspacing issue though. The bolt can be headspacing properly and still be out of timing due to the rollers being out of tolerance. That's impressive though, I've never seen a receiver dented like that from the rollers pounding on it.

My Vector V93 came to me (from Vector) with bumps like those.

They're really not that big of a deal...

You might see them above the mag also where the bolt hits the round in the mag.

 

[nfafan]

Yeah, had one, actually 2 - first one lost all bolt-gap after about 100rds.

Second was a factory replacement and was excellent, rock steady bolt gap at .014 over multiple range trips and over about 600rds.

Sold it as I didn't want the proprietary mag issues even though it was a sweet shooter. My 20" AR shot as well and is readily compatible with my .22LR kit.

If you buy one, be advised that you may have to send it back if it is not right.
