BRNO bolt shroud disassembly
Anyone know off the top of their head how to disassemble the bolt shroud on a BRNO 602?

they came with a dissasembly tool that you used to compress the spring and remove the knurled retainer, very similar to a Model 70. Then everything slides out the back of the shroud.

It is easier if you first release it from the cocked position by grasping the shroud and pushing the firing pin point down and letting the lock pop free

There's an exploded diagram and parts list pdf available over at NitroExpress, if that's any help.

Yep, they apparently came with a combination bolt strip tool/screwdriver, in the wee bag that also held the changeover trigger parts for the conventional trigger setup. Drop TilleyMan a PM over at NE for detailed info on bolt stripping; don't think he's a member here.

TilleyMan also has a comprehensive guide to the ZKK60x's in preparation. From his past posts, some of the disassembly can be a bit tricky, like the trigger mechanism. NB: this link will only work for logged in NE members: http://forums.nitroexpress.com...eneral&Number=161586

Thanks guys... I see what you're saying, and it makes sense.

Just have to find the little key/tool now!

there must be thousands of those little green bags that came with ZKK's with a standard trigger and the little tool, in the back of drawers and gun cabinets. I wish I could find a few of them becasue all the ZKK's I come across have those dang single set triggers.

To compress the spring, I just use a pair of sidecutters to slip over the mainspring and unload the retainer.

Ditto. Someone should reproduce the standard trigger and get rich.

AHR used my 602 to try to make a "standard" trigger but said they couldn't. I think what they really meant is that it wasn't worth the effort. I wish they or someone else would make a Timney-like trigger, I would certainly buy one.

Wouldn't think it'd be that hard for a good gunsmith to make a standard trigger blade, and the small flat stock anti-rattle spring for it.
One of our better smiths over here has done a few.

LH trigger is the ZKK600 & 601; RH is the 602. Coin is 1.24" across flats.

I don't like to get too far from the thread, but...does anyone know if the big 602 magazine (bottom metal) configuration is same as the CZ 550?

They are the same, but the trigger on the 602 is attached to the bottom metal.
