CZ452 + Brooks Kit = broken gun. ***Now with CARNAGE!!!***

hmmm a little camoflouge duct tape oughta fix that up nice............
but honestly that sucks, in future one conk is a good test unless of course you plan to fall down the stairs with your rifle, then i guess the conk conk conk conk makes sence :D
 
Jeez Bob but your macro photography sucks worse than mine, lol. I think you can very easily fix that stock. It's only a .22 so there is no recoil to worry about so a cyano repair will hold just fine. Just take the action out and get some thin cyanoacrylate, hold the stock so you can put some leverage on the cracked area to open the crack just a little and I mean a little, and wick in the cyano then get leverage to close the crack and hold it for a while. I would advise about 12 hrs. Get your setup to hold the stock with pressure closing the crack ready and working before you apply the glue as it does its initial setup in just a couple of minutes. Keep us posted,

Great thread guys. I was just wondering if I should do the same thing to mine. I think I will play with the trigger adjustments first. I have the wood stock and it sure is a nicely put together rifle. Seems all of the guys in the shop where I got mine have only just adjusted the triggers at best but most seem happy the way they are. First left hand bolt 22 I have ever seen. Glad I passed up on the tupperware. Got a nice chunk of wood on mine. Shoots like a house on fire already and only a couple of boxes thru it.

I agree, be careful & not get too much adhesive outside of the repair area.( or on your fingers) :D Give it a go, you may not require a new stock after all.

The stock may require some paint to mask the repair. Even if you have to repaint the entire stock you will still be ahead.:)
 
I just picked up the springs only from a CGNr so will go lighter spring, no shim. For bump tests, may want remove scope too.

Like how you made it look like an accident and the posting on CGN just adds authenticity. My guess the this happened exactly 5 minutes after you already ordered the new stock. Nice touch too to ask for ice cream so wife would witness the "accident".

Unless I decide to fix the broken stock this project will be shelved for a while. I have 3 other gun build projects going and not enought cash dedicated to complete any of them.

For bump tests I agree - remove the scope, (and stock.)

I was wondering about clamping the barreled action to a hunk of wood to simulate a stock and complete my testing.

The thought of a trigger that can go off with a hard drop really bothers me. Mine has failed this test with the thinnest Brook's Kit shim and heaviest Brook's Kit spring (at the expense of my stock.)

Since I appear to be singular in the severity of testing I'm wiling to submit my rifle to, I wonder how many CZ452 owners have triggers that would fail my "conk test".

Would your "Brooks Enhanced" CZ452 trigger go off with a conk on the butt stock?

Should you care?

Honestly Bob I don't think you should care. Do you plan on giving your rifle many hard drops straight on the buttstock? In 40 yrs of being a "gunnut" I don't think I have ever dropped a rifle hard enough to set it off no matter how light the trigger. That said I don't think I have had a gun with a trigger under 2#. When the bonk becomes hard enough the inertia of the trigger will fire the gun if the safe is off. If the safe is on and it fires, or the gun fires when the safe is taken off after a moderate bonk then you can start to worry. Any gun can be made to fire if you hit the butt hard enough and believe me, breaking the stock is hard enough.

I thought a 12" drop onto a hard surface was a "moderate" drop.
In retrospect, maybe the "10 conks in a row" was over the top.

What surprised me was how easy it was to make the trigger go off with 3 out of 4 springs in the kit, using my hand on the butt or a "light conk".

Anyway, thanks for the discussion guys.

good to hear your airing on the side of caution.
My two cents, the stock you use should be on the gun for any type of safety testing. And second, what ever test you decide to do to it , do it on the stock unmodified gun first so you aren't chasing existing problems.
 
My first thought on reading this thread was who would hit their gun hard enough to break it? Second thought was, "my [family member] lost the use of his right hand when a friend gun got dropped and it went off, clipping the nerve in his sholder." I would expect brooks to mention procedures on how to test to see if its safe, but I suppose this is a liability issue for them. Personaly, I would just emphasise to my kid to never close the bolt with a round in the chamber until its go time. Problem Solved. My 2 cents.
