CZ 452 trigger spring & sear kit - Awesome!

The CZ trigger kit - the best $15 you will ever spend!

If you own a CZ 452 or CZ 455 (also called a Brno Model 2, 4, 5 etc back in the old days) & want to improve your trigger drastically, all you need to spend is $15, yes trust me, this $15 kit is infact a better trigger the the $150 kit sold out there, & it is very very safe when properly setup.

Check out the Eric Brooks CZ452 spring kit, its just brilliant.
Dont worry too much about the Pin & Spring Removal fixtures he also sells, you wont be changing your trigger that often & its not too hard. It needs a bit of patience, but can be done alone, though ideally get a mate to help & you'll be sweet.

The best thing about the E.Brooks kit is that you dont need to make any modification of any kind to your original rifle & its parts. You keep your original CZ spring & parts, just put the Eric Brooks stuff in & when you want to sell the rifle, you can just drop the original parts back on!
There is no grinding, polishing or modification of any kind.

He sends 4 springs, of which the 4th one is infact harder than the stock cz spring so its kind of pointless. Number 1 is way too soft & my gun went off when I tested it by dropping it on the wood floor, so thats not recommended for all you hunters out there.

Ok its not the easiest thing in the world to do with just your 2 hands, & for your first time having a friend assist is probably a good idea. But after youve doen them a couple of times, you can just do it by yourself. Just be careful to ensure you are working in a relatively clean space that doesnt have too much furniture around you, because as a first timer its likely the spring will bounce on your first few attempts & dont we all hate it when the freakin thing decides to roll under a heavy cupboard.

I use spring number 2 + Red sear, & a mate of mine used number 3 & we're both very happy with the results.

As for the sears, I highly recommend you play with the combinations, but as always, if u want a trigger that breaks nicely while being safe, what you'll need to do is put a tighter spring with a thicker sear. For more safety, use the tighter spring with a thinner sear.

For all hunters who use it mainly for field use, I recommend spring 3 + sear 2

If youre only ever going to use it in the range & dont think it will ever drop when loaded, then its ok to go with spring number 1 & sear number 3.

The way to look at it is, springs are your weight & sear are your pull length/creep.
In the perfect world youd use the lightest spring with the thickest sear but I dont recommend that.

Like everything springy, wear & tear will eventually get your spring. Ive had a good 1000 shots out of mine before I noticed the trouble whereby the hammer would not cock when the bolt was closed. The inherently design of the CZ is such that if you didnt have a spring there or a very weak spring, it wont cock which is great, & thats why this kit is pretty safe.

Usually, when your spring looses tension you either buy a new kit, or change to a different spring.
But what I did was put a few extra spacers & washers on the cylinder just before the spring to get the tension the way I like it, & that infact allowed me to precisely calibrate my trigger!

The way to notice if the spring is starting to shit itself is that some day you'll start noticing your trigger is much lighter than you originally thought it was, well, highly likely your spring needs replacement or washers or whatever you want to do.

So, if you want a great trigger thats extremely customisable & will last pretty much forever, save your $150 on buying a so-called CZ trigger kit. The most popular CZ trigger kit is made by Timney & 2 of my mates went down that route.

They said they didnt like the idea of modifying the stock trigger & wanted to keep it aside.
But what people dont realise is that you are NOT MODIFYING ANYTHING!

After trying out my mate's $150 timney kit, I actually found his to not break as crisp! He loved it so thats great for him, but to me, being light is not enough, it has to be clean.
This kit allows you to customise your trigger the way you like it

It would be even better if Mr. Brooks gave people who knew what the wanted the option of buying just the 1 spring & sear they need rather than always selling all 4 in a pack, but heck for $15 Im sure you can live with that.

Looks like this guy here on YoDave is also doing something similar to the Eric Brooks kit above. Never tried his stuff out, but do let me know if any of you have.
Back when I got the eBrooks kit, I dont think he was around.

Happy Shooting people!
