I received the spring in 1 day , thank you for the excellent service ! The Stock spring would not let me adjust below 2.6~3 lb on my CZ455 , 17 HMR . With this spring I can go lower and set mine hair below 2 lb and works excellent.
The spring worked as advertised. I now have a reliable 1 lb. trigger.
Installed the spring kit on my cz 455. Love the spring kit, easy install, basic tools required. This was my first purchase from MCARBO and wont be the last. Looking forward to the cz 455 mag release.
The 455 Lux is already an excellent rifle, but this spring kit is like the frosting on the cake. Easy project and well worth the time. Now feels more like my CZ 455's big brother (a 527 with the set trigger). Kudos.
Installed this trigger spring kit on my 452 American. Very significant trigger pull reduction along with less creep. Very happy with this spring kit.
Made a big improvement on my cz 455 love it
Good upgrade for your CZ
I found it very easy to install and it worked fine. Previously I had adjusted the trigger to as light as it would go which was 2 1/2 pounds; not bad, but I wanted it lighter. The new spring brought it down to 1 1/2 pounds and now it feels real good. I did think that $12 was a little high for the spring, but it works as advertised.
I followed the CZ tutorial video. No issues. Go slow, take your time, no distractions, and as he said on the video use lite taps when tapping out your pin and lite taps when putting it back in. After I replaced the spring I took it down to the lightest point it would go and then went back up just where everything engaged. Very nice trigger pull. Thank you.
I watched the YouTube video on replacing the trigger spring on the CZ 455. I ordered the spring. I came in a couple of days. It was adequately packaged and arrived in good shape. I did exactly as the video showed. The change out took about 10 minutes and was a breeze. I don't have a trigger pull scale, but I can tell you that the difference from the original to the M*CARBO spring is significant. The trigger pull know is perfect for my Squirrel Gun. When I get a chance to shoot it, I am sure that tighter groups will reflect the lighter and smoother trigger pull. An easy and inexpensive alteration to your gun that will surely improve accuracy.
I have purchased two of these springs .... one for 455 american 1.5 lb .... 455 training rifle 2.0 lb. They work great 5 STARS
I ordered the trigger spring for my CZ-452, which I found easy to install and far superior to the heavy factory trigger spring. When removing the rear trigger pin, be sure to use a small diameter punch, as it is a small pin. Make certain everything lines up to in re-install the pin, then adjust trigger pull to your satisfaction and safety. This spring up-grade made my CZ-452 .22 L.R. a real tack-driver!
I was able to perform the trigger upgrade thanks to the great video produced by M Carbo. Instructions were clear, complete & much better than other half ass videos found on U tube. Cost of the part was very reasonable. Shipment was extremely fast & I even got a brake on shipping charges ! Couldn't ask for anything more. I'm very happy with the way the trigger upgrade turned out.
Delivery was as stated. Prompt. Instalation was very simple. Instructional video was well explained and easy to follow.Trigger pull is now at 1.4lb and safe. Am very satisfied with this CZ trigger spring.
I was wanting to improve the feel of the trigger on my cz 455 varmint evolution and this was a good option. I thought I would end up buying a drop in trigger however I chose to try this less expensive option first and I am glad I did. It feels really good and lightened the pull a good deal. It preforms very well
Good for a 76 year old salt. Trigger better-than-expected . Video helped a lot .
