I highly recommend this product. The trigger on my new CZ Scorpion Evo3 S1 was 9+ lbs. I purchased the MCarbo trigger spring kit and followed the video on their web page. Disassembly and assembly was a breeze. My trigger dropped to 4.5 lbs. I highly recommend this simple inexpensive upgrade to all CZ Scorpions. Make sure to purchase a vial of Synthetic Grease w/ PTFE. It only cost $1.95 and helps in the installation and provides proper lubrication. I give this product 5 stars out of 5.
A pretty high profile competitor makes a similar kit for the scorpion. But Mcarbo has engineered a better option for just a couple bucks more. My Evo3 S1 no longer has the stock military grade feel. Smoother, lighter, still a crisp sear and reset. Nice job. A better choice.
Definitely recommend, huge difference, not too difficult to install! Also it's a considerable upgrade to a great weapon for a very low price! 10/10 would recommend!!
Finally got my CZ scorpion bad thing was 10+ pound trigger pull an gritty installed the kit constant 4.8-4.9 Thank You MCARBO an no more grit!
Extremely fast shipping , shipped within 2 hours of ordering,,,
Installed the kit a few days ago, the video made for an easy install. Huge difference! Very pleased. This is my second kit from MCARBO and I’m about to order two more for my CZ 75s!
Choose M Carbo because they include spacers and have a really good installation video. Very nice product, good company to purchase from, easy to install and works very well.
I have used an MCARBO trigger spring before with great result and wanted to try the one for the CZ Scorpion. Installation of the kit was easy and the how-to video was very helpful. The kit took the trigger pull from 9 lbs to about 4.75 lbs. This is a terrific product!
Great product. Simple install (thanks to great video from M*Carbo). Reduced pull weight by 3-3 1/2 lbs. Wish it would decrease length of pull, but for a simple spring kit, it’s a big improvement.
I purchased the M*CARBO trigger spring kit a week ago and couldn't be happier with that decision! Shipping was fast, the item arrived on time and was installed quickly with the aid of M*CARBO's very detailed and well explained video on U-Tube. My Wheeler trigger pull gauge now tells me that the trigger pull weight on my CZ Scorpion EVO3 S1 dropped almost in half.. down to 4 pounds, 11.6 oz. From one Combat Veteran (Vietnam) to another, thank you M*CARBO!!
I rarely comment or review but this is the 3rd spring kit I've installed with awesome results. Shipping is as fast as it gets. Thank you for your Service!
Great product, easy to install great delivery I would recommend to anybody that wants a 9 pound trigger pull down to about 4.5 lbs
Does what it says. Relatively easy to install, shims can be a bugger.
Took my scorpion from a terrible 9lb trigger down to 4lbs ! easy install with a great instructional video on the site.
Ordered thru MCarbo on line and it arrived very quickly. I have not install the new trigger spring assembly yet though. Service is fantastic!
Recently purchased a scorpion and everything I've seen had said the trigger pull was the biggest issue. I waited for the trigger and safety lever I wanted to come in before installing so I would only need to disassemble the lower once. Product shipped extremely quickly and arrived within a couple of days. Install wasn't difficult. I checked before ordering to see if the screw holding the trigger group was welded in before ordering. Other companies have the needed drill bit and replacement screw if you run into that issue. I the the installation video on the TV, set the scorpion on the coffee table, and was finished within half an hour or so.
