I have a CZ 602 .375 that I bought used years ago from a fellow that hadn't put a box of ammo through it. I don't believe that it has had anything done to it other than having a scope mounted. I have probably put about 300 rnds through since I have owned it, but for the most part it hasn't had much occasion to come out of the safe. Since a trip to Africa now looks like it is on the horizon I am going to dig it out and send it off to the smith. My question is what should I get done to it? Glass bedded and cross bolted i assume are pretty standard?....is there anything else I should look at? Are there any improvements to be made with the set trigger? Thanks for the help

I would replace the factory set trigger with the factory standard trigger, if you still have it. That's the only thing that needs to be done, besides mount a scope in QDs. Also, the safety is fine the way it is, despite what M70 fans may say.

I've never heard of split stocks, off center barrels on ZKK602s or any of the other problems you hear about on CZ550s. You could glass bed if it makes you feel better but most of the problems on CZs seem to be with the bigger calibers like Lott and Gibbs. If the rifle has over 300 rounds through it, probably OK.

Yes, replace the factory set trigger with the factory one-stage standard trigger.

Replace the bassackward safety with an Ed Lapour 3-pos wing safety,
unless all your firearms function with safety pulled to rear to fire, and pushed forward to make safe.
Most of us are hardwired to push safety forward to fire and might screw up in a tight spot with a bassackward safety.
If it is plains game only, it could only cost me a blown chance, as the meat and trophy get away while I fumble with pulling the trigger with safety on.

Glass and pillar bed and crossbolt.

Done.

Dang. I did not get a "standard" trigger when I bought the rifle. I will see if I can track one down.

Is there an advantage to glass "and" pillar bedding? rather than doing just one or the other?

Never hurts to over reinforce your stock. Crossbolts, glass bed, and a wrist pin should pretty much cover your for a 375 though. You can do all three of those at home too with some glass bedding epoxy and some all-thread if you're up to the task.

Thanks. The rifle has been sent to Corlane's (BC). On the menu is: Glass-bedded, Cross-bolted (x2), Trigger tuned (we'll see how well that goes...no standard trigger yet), 3/8's steel pin (wrist), limbsaver recoil pad, sling swivel stud removed and replaced with one mounted on a barrel band. So...a few weeks from now she should be "safari ready" Thanks again for the help.

Very generous, those are hard to find.

Duane - you said that AHR has a replacement trigger for the ZKK-602. Is this a very recent accessory? I sent my 602 to Wayne last year for development of a trigger and a Model 70 style safety. He was able to make a safety for it but told me the trigger replacement would not work. Are you talking about a 602 trigger or the CZ550 trigger?

Those BRNO ZKK 602 triggers are on a pin through the trigger guard. Remove the bottom metal and the trigger goes with it,
other functional parts of the trigger mechanism, sear, etc., remain with the action.

Easy to replace the trigger yourself. Drift out the pin, remove the funny trigger, and situate the single-piece trigger in the trigger gaurd,
then slip the pin back in.

This does point out the importance of pillars with this gun.
It can be as simple as epoxy gluing into place the spacers that come with this rifle, like Mausers, during the bedding process.
It strengthens the stock and will better maintain the bottom metal to receiver spacing,
upon which the trigger engagement is dependent.

Pillars can also be made of threaded brass or stainless steel tubing like lamp fixtures, or aluminum or stainless steel or brass pillars from the gun parts houses.

My BRNO ZKK 602 (.510/460 Weatherby Improved Jenkins and Berry) has a Wisner safety and the curved, one-piece factory trigger.
It is pillar bedded in a McMillan stock with whatever pillars Jenkins liked.

Forgive the ignorance, but does one get pillar bedding as an alternative to or in addition to glass bedding?

It is just gluing in some action spacers when the regular glass bedding is done.

Glass bedding varies from just a dab of epoxy in the primary recoil lug recess (POOR), to a really good job throughout the insides of the stock.
Glass beding should include from tang to forearm tip, including the barrel channel with free floating, magazine box reinforcement in front-sides-back, tang with .050" relief to prevent stock splitting, and including pillars,
to prevent stock compression/splitting, and allow better torquing of the action bolts: Solid.

Pillar bedding is part of the regular glass bedding job of any GOOD gunsmith.
