Spring/Piston SLAVIA 630 REBUILD/PARTS HUNTING!!

[Danman]

Hello all, I've been wanting to start a thread on my only non British air rifle! I have owned this gun since I was probably 15yrs old, and is my second gun following a crosman. I sold the crosman and got this for about $150 at the local Home Hardware. I plan to probably chop the barrel (2 or 3 inches max) and would love to hear some thought on that! My order is in at Vortek for a new main spring after HOURS of measuring springs, guide, piston, researching on forums watching videos on it in Russian and possibly other languages I don't know. I have a new main seal, and some new sling studs, and gonna give internals a full cleaning and lube job. Gun shoots a bit over 500fps with the crosmans 7.9gr pellets and I'm hoping to boost that to about 650fpsUs lucky Canadians got the detuned, twangy, undersized, sloppy spring in our slavia guns so it would be safe for our market . Let me know if you have ever shot, owned, sold a Slavia air rifle!!

I still own a Slavia 630, it's still in its original 1990s box.
I'll get some pictures at the weekend. It's due a bit of plinking time .

Absolutely!! To be honest I'm hoping to put the gun to 'original hp' specs as I don't want to trash it or make it harsh. I believe it will be sweet. Here is the chrono numbers from it before the tear down. Off my pro chrono Name: Crosman premier .177

SD: 4 ft/s
Min: 507 ft/s

Power Factor Average: 4
Power Factor Low: 4
Power Factor High: 4

That's definitely lower power. From memory mine is in the 700s.
I'll get the chronograph out.

They are still a well regarded air rifle in Europe. Definitely one of CZ's best springers.

Many trained with the Slavia series at summer camps etc.

When cz stopped production, the whole outfit moved to Slovenia, then renamed as Perun 730.
All parts are the same.

I'm still trying to obtain a Perun, fetching silly money lately. Nostalgia .

 

[Danman]

CZ is know for there firearms n barrels, but these springers are solid too! North America parts are not plentiful but they exist. I'll keep the updates coming. I have stuff coming from the states, British Columbia for it (I'm in Ontario) ...parts: cheap, Shipping: less cheap! They are sub-12fpe for sure, this one being like sub-6 . It is technically shooting too hot though, judging by the chrono Barrel is staying as is till build is done and lots of pellets go through it, then I'll decide.

 

[Spinach]

I've known guys buy the Slavia just for the barrel. I've been tempted but prefer to keep things intact.

Parts are still available in Europe, just need to study languages harder.

Ohhhh this hobby.

Just had my Slavia out, plinking perfectly.

Chronograph shows 173 ms, 8.14 joules.
Or approximately 566 fps, 6 ft lbs. Using jsb exact 8.44 gr.

Speed was lower than I recall, perhaps last time I used lighter pellets. Very nice to shoulder and shoot, I had forgotten how smooth it was.

It's never had a scope mounted, always shot open sights. I probably need a scope now, eyes and age.

It's a later 630, 1997. Box and rifle marked, Czech Republic. Older models have Czechoslovakia.

A couple of poor pics.

 

[Danman]

Love it that you still have the box for it, and yours seems in better shape than mine! Yeah they are supposed to shoot in the low 700s with 7 grain light pellets. I once shot a 13gr monster diabolo out of mine. I can't believe it didn't get lodged in barrel looking back now. It even hit the target 25 yards away! At the very bottom of course. The slav did not enjoy the experience. I am still waiting for my spring from vortex but my new sling studs and piston seal got here.

I've decided to leave it at the power it currently is. Smooth .

Probably will finally put a scope on. Just need to find something.
Just last month I gave a friend a 25 year old Bushnell, it would have been perfect. Life .

 

[Danman]

Ah brutal! I have to try scope rings but I've heard they are an odd 13mm dovetail? Gotta see if my 11mm Hawke ones will fit. Definitely won't be needing a high power scope just a 9x shall do. A 50 yard gun she is not.

 

[Danman]

Well this is frustrating. Still waiting for my vortek spring to show up! Was made, packaged, and shipped mid February. It hit the American/Canadian border next day and has been stuck in customs since then. (3 weeks and counting now) Paid more for the shipping than the spring. The excitement is mostly gone, now I just hope it arrives. Gonna have to dump some stress with the S510 this weekend perhaps.

 

[Hateful McNasty]

Maybe use arh with coil size and count you want as a back up and compare spring . It may not of got hung up . Or double your chance one got straight through..lol.

 

[Danman]

Yeah it was $100 after shipping. Gun was $150 ... oiii. Dont care about the cost per se but if it's lost then I got $100 into nothing. ARH is a spring company? D&L had some universals but the vortek was custom ordered and built for this gun. At least I have the measurements still!

 

[Hateful McNasty]

Just got to ask what's he got

Here's a deal that I guess fits

From this
Upgrade spring for Slavia 630!

Then to this ?
Airgun Mainspring (UTL-AC-002)

Sometimes it's a next best kinda thing

 

[Hateful McNasty]

Ya, I guess customs can throw a wrench in something you want .. I don't see nothing going easier with all that free trade agreement ..

Well one day if it don't get lost it will show up .. lol

Good luck...

Hey thanks! I've been down that rabbit hole already, and I may have to go that route for the slavia if this one doesn't show. All I want is another 100fps . Ive heard stuff can be stuck in Customs for months. It shoots the cphp pretty well @ 500fps +. The springs are definitely cheap enough from D&L. I'll wait for now.... Going shopping at Air Gun Source in person next week, that should distract me for a while!

I think one guy dais that one # DL spring was higher power and fit. Like normal #2 was 500 fps but like the #6 was 700 or something .. .

I guess if wanting to do 10m to 20y 500 is fine ( for me anyway).

Anyway out of country stuff can be a drag on shipping or customs .. few things ain't no choice .. especially air gun parts .. USA is a parts desert vs UK ..lol

 

[Danman]

It is here! Customs opened it up and got hung up on the "mystery" packet of grease... so it sat for over a month there. Man when it rains it snows, got new mounts for my S510, new scope and ammo for Ghost, and now my spring is here all this week. Excitment is back on! Might throw the open sights back on and try them again, glad I kept them....can't ever go back to that horrible crosman scope.....and I'm tapped out on air rifle spending for at least a month

 

[Danman]

Well she's a nice fit in the guide! The old one just fell out (zero resistance) when I disassembled it a while back. This one should give those little 7.9 pellet some thrust!?

 

[Danman]

All together again! The old spring basically fell out, the new spring I put back end into my vise and pushed the action into it as hard as I could and threaded it home. Not sure what was going on but the first few shots were definitely dieseling. Put some supplied grease on spring, and rws chamber oil and a dab of silicone grease onto piston seal end. Got some smoke and bad smells with the light crosman 7.9s. Man does it sound better, twang/buzz is 100% gone, crisp almost like my TX! Open sights are back on! Shot a friend's gun last weekend and I forgot how fun open sights are close range. I had issues with getting windage right (20 some odd years ago!?) so opted for the cheap scope back then. Will definitely post some groups and speeds once it's settled!
