Artemis Cr600w Co2 rifle Build. (stormrider, spa ,chaser type) pic heavy

Today I made custom tight clearance brass pins  for the trigger group.
Very Fiddly work. I made them with the shoulder next to the head so they kind of pressure fit on one side.
I also added a longer set screw for the trigger with a polished cone point, which smoothed out the trigger more

[Walther]

The trigger is pretty decent but could use some more improvements.
So I replaced the the trigger spring with one from under the flint of a good ol bic lighter. I used about 1/4 to ⅓ of the spring after making a spring guide out of a 2mm x5mm stainless bolt with the threads shaved off.

Next replaced the trigger set screw with one long enough to poke out each side of the trigger 1mm. This reduces take up and travel and kinda mimics a two stage.

I made sure to bang and tap the stock a few different ways to make sure it can't fire a erroneously. If you do it right the safety works perfectly as the safety engagement part of the trigger is just resting against the safety.

It now has very short pull with a clean break at somewhere around 13 oz.
I can post pics if anybody wants.
Happy Friday I am B deep in a classic style maragarita made with my homemade key lime syrup and Reposado Tequila:)

Well done! Great to see outstanding workmanship and ingenuity. I am thinking of picking up one of Wes's(AirgunArcheryFun) regulated PCP rifles's in .177. I think your post may have convinced me to pull the trigger. 

PS...I lived in LoLo for 15years...I miss the NorthShore.

Thank you!
These rifles have a lot of potential if you can do some work on them. I may have some "extra" upgrade parts available;) ie bolt ,carbon alu muzzle brake
Where are you now? Wes is great A++ guy to deal with.

I’d like to say how nice your carbine is in the original post. It’s looks great, what kind of power and accuracy does it give you?

[Ribbonstone]

Question....does your safety still work as a safety after the trigger mods?


Have gotten a good trigger pull on a Gen. I version....but then the safety, while it would click-click in and out as it always did, didn't actually stop it from firing when it was "on".  Figured out a quick-n-wasy cure to make it work correctly and keep the trigger pull.

Realize I nearly never use it (I just won't cock the rifle unless I'm going to shoot it), but for those once-in-awhile situations it's useful to have...and very useful to have when others are allowed to shoot it (As I just don't want to get shot by a newbie).

Thank you Toddspeed, I am in Canada so it is tuned to jsb 15.56 at 490 fps to make it backyard and basement friendly, power is not my goal . After barrel recrowning it is Very accurate stacking pellets in my 10m basement range. I like to build stuff and I'm recuoerating from knee surgery so it is "busy work" for me.

My safety is still functioning as it should, with the longer around 5mm set screw the safety just clears the stub on the trigger blocking it. I am very safety conscious so  a working safety is a must have so I have tapped it with rubber mallet a few different ways to make sure it can't fire on its own to check. The bic lighter spring mod really worked well to lighten the trigger.
Is there anywhere you buy Gen two trigger? I have looked all over and found very little parts availability..
My Next mod will be the Bstaley mod , i'm just researching setups now..

[Walther]

Did the bstaley mod recently. Easiest mod ever . Turned out my cr600w has short valve stem it only took one 113 o-ring which landed right at 488 fps where I wanted it. Next to test how many shots before fps drops.

[avator]

Don't know what you know about the BStaley but, your goal is to get a nice bell curve. The first shot and last shot should be very near matching with nice steady rise in the middle. The lower the high point of the rise, the better.
Good luck... please post your results.

[nervoustrigger]

On an unregulated PCP, the goal is a longer useful bell curve at a reduced velocity.  On a CO2 gun like the CR600W, it's basically a regulated system (albeit temperature sensitive per the nature of CO2) so a bstaley can be used a little differently to reduce both hammer strike and hammer bounce to improve efficiency.

When setting up a CO2 gun, I generally chronograph it and see where it's running wide open, then I add O-rings and shims until the velocity just begins to drop.  That tends to do a good job at reducing CO2 usage, typically netting anywhere from 50% to 100% more shots, and a side benefit is it becomes less sensitive to temperature changes.

[Walther]

On my cr600 it was shooting 498-515 which is a little high for my needs.
With one  o ring it dropped it down to 480 fps with the next 5 mags  within 6 fps , then it drops off suddenly with each subsequent shot dropping by 8-10 fps .
Very happy with the results.
