Review
I have installed this kit in two different rifles. Amazing consistency both rifles pull just over 1.5lbs with nothing other than this spring kit. If you haven’t bought and installed this you don’t know what you’re missing. Semper Fi.
I’m a veteran and always like working with veteran owned companies. The product was great but the service and follow up is among the best I’ve ever received.
I purchased this trigger spring for my sons 452 Ultralux which he uses for local competitions. This took a nice trigger on an awesome rifle and made it an amazing trigger on an awesome rifle. Well worth the price. Easy installation thanks to the perfect instructional video by Mcarbo. Well done guys!
There are several CZ 455 springs on the market, but I decided to purchase the M Carbo based on reviews. I am very happy with my selection. Installation was under 5 minutes. The results are fantastic. I must say, I installed this on a secondary CZ 455 I use for plinking and practice. I have a CZ 455 action in a custom F-class built with a Timney trigger, and the M Carbo spring is nearly as good, if not equal, to the Timney trigger.
We have several CZ's rifles. They all had the same (17 HMR, 22LR) spring. They needed to be adjusted and the best way we found was using these springs. The triggers released at 2 1/2 pounds instead of 4. Watch the videos, it couldn't have been easier. Thank you
What a great improvement over the old trigger pull. These guys rock!! Thanks for all you do..
When I ordered the cz springs, I sort of doubted the advertisement of 50% less pull. After installation I measured trigger pull and they performed as advertised. Great product.
Great product and awesome customer service! Installation video was super helpful. Highly recommended.
Easy installation on my CZ452. Trigger pull prior to the Spring Kit 1.70 lbs. Installed new spring and trigger pull is a consistent 11 oz.'s > Perfect for target shooting. Thanks MCARBO!
Received kit in 3 days. Quick instalation. Reduced trigger pull from 3 lbs.13 oz. to 1lb. 13 oz. according to my Lyman digital scale. Will highly recommend.
I have ordered several different products from M*Carbro. All have performed as advertised. The service is second to none. speedy delivery was the best I've experienced from any body. My thanks to all the folks at M*CARBRO>
Super easy Spring install on my CZ 455. great adjustability.
I put this spring in a CZ 452 in 17 HMR, and it worked great. The trigger pull is about 2.5#. Thanks for a great product. I purchased a Rifle Basis trigger for another CZ 452 I have. It cost $85 and it gives only a slightly better trigger pull, mostly because I was able to adjust the sear engagement to remove all the creep. I would be just as happy with your spring in that rifle with the factory trigger.
Purchased two CZ 455 trigger springs and they are great. Don't have a trigger gage but the triggers on both my 455's are far lighter than the OEM springs. Both rifles passed the safety bump test and I am very happy with the triggers. Watched the video and made the installation easy. Also super fast shipping.
I installed one of these springs in each of my CZ 452 & CZ 455 rifles. They were very easy to install after watching the video. They were 1.6# & 1.8# and I adjusted them to 2.1# & 2.2#. Made for a very smooth & nice trigger after installed. I also used Super Lube with PTFE. Yes, they do pass the drop test as well!
Well worth the money. Installation took less than 5 min while following the instructions from the video.
