Measuring my CZ Scorpion EVO S1's trigger maxed out my spring trigger scale. Definitely over 8 pounds. Removed trigger assembly (and I found the assembly hold down screw loose, worth checking every now and then for loctite'ing it) I followed the video as I disassembled and then reassembled with the new parts. I forgot to order the grease so used some gun oil to get things to stick together. I had a little difficulty keeping the washer by the return spring in place but finally got it. Initial testing reduced the pull to 5 lbs and after about 10 rounds of dry fire I noticed a drop in pull. Measuring showed 4.5 lbs Right on the money! Well worth the price and half hour of my time.
Complicated install, but not because of the product, the design of the gun itself is odd. But the results are worth the labor. Trigger pull down noticeably
My Scorpion trigger is feeling like it should be light and crisp!! Thank you!
Took less than an hour to do. The video is clear and concise. Use the grease, makes the job that much easier. Cut the trigger pull in half. So much nicer. Great product for a great price from a great team.
Unbelievable difference in trigger pull! Super easy to install using their very well made installation video.
Still a long pull obviously, but that weight is a lot better! Great youtube video for installation!
This simple kit transformed the cz scorpions trigger. It went from kind of gritty and heavy to smooth and light. Watched the install video and installing it was very easy. I would recommend anyone with a cz scorpion to buy this. It makes an almost perfect gun perfect.
First time ever working on a firearm and it took me all of 30 min to complete! Highly recommended!
Your installation video is the best I could find for the Scorpion trigger spring kit. Easy step by step. Two washers in the kit sold me on trying your kit over the other internet offerings. Simple but logical reasoning made sense to me. Didn’t put a trigger weight gauge on it beforehand but can assure others the weight was reduced by at least half after upgrading. Great product.
Worked great. Cut trigger pull in half and really smoothed it out. Highly recommend. The install video is excellent also.
Takes about 30 minutes to install. There is only one tricky part. When watching the installation video, be SURE to cock the hammer back - after the quick function test - BEFORE you re-install the safety assembly and re-insert the trigger assembly into the receiver.
Make sure you purchase with the trigger kit a couple tubes of PTFE grease part # 19970100102 and one two ounce bottle of MCARBO MIL-SPEC CLP / MIL-PRF-63460E / Cleaner + Lubricant + Preservative. These products make installation and final lube much easier. You will be amazed at the smoothness and difference over the stock trigger assembly. WATCH THE VIDEO!!
This is the fourth Mcarbo spring kit I have purchased and continue to be amazed how easy they are to install with provided video and how well they perform. I installed this Scorpion kit and the trigger pull from hell turned into a smooth firing quick reset tack driver. Thank you for a product that doesn’t require a gun smith to install.
I installed it the night I got it in. Absolutley love it. Their video provides a really good step by step of disassembling and reassembling the gun. Good job guys.
Very noticeable difference in the trigger weight ...highly recommend!@
This spring kit was great and video couldn’t have made any easier Outstanding job Mike
