Zbroia Kozak 177 arrived today

I've tested Nielsen 15.5 grain slugs out of my Kozak at 50 yards and was very impressed with the results.

That one flyer was me using wrong hold over point.

This is 6 shots all in same hole.

Shutik, I see that the slugs works well on your rifle, I also asked a friend of my to cast some for me.
I started making a complete new shroud and end caps with a 1/2" UNF threads to fit a external silencer, also a larger diameter shroud tube (25mm OD) for more internal volume, here are some pics, not finished yet, I still have to tap the front end cap with a 12X1mm to fit on the barrel, drill hole on the end cap shaft for the blowback in the shroud and thread the tube and the back end cap, then anodize the parts.

Hey, about the trigger adjustments.

is it correct, that you can adjust the weight und sear engagement ?
and maybe with adjustment to the linkage the lenght of the first tage ?

how can i remove the weaver rail ? i removed all screws on top of it but its still not moving ?
i need to look inside the barrel.

is the regulator inside the airtube ? it seems that my regulator is set around 95-100bar.
it could be lower because im limited in energy levels :(

thanks!!
 
Ramjet66, I decided not to use the original shroud as it has a very narrow inside diameter so I am using a 25mm OD tube for it with a ID of 22.5 mm, that gives a slightly more volume, the stock tube has a 19.4mm ID. I tryed the adaptor just with a silencer and quiet down a lot (it is backyard friendly) but still not for my liking (I like whisper quiet), will try again when the complete kit is ready, now I just need to thread the tube and the end caps, drill a hole on the shaft of the front adaptor and make an internal baffle for the shroud but I think I will need a larger diameter silencer as the ones I have are 30mm OD with a 27mm ID and 127mm long, I am thinking machine a 35mm OD with a 32mm ID for a bit of more expansion volume.

Sorry but I havent tyed to adjust the trigger as I like the factory set up, I thought that the reg was set at 150bar, do you have a 12ftp rifle?
