CZ Scorpion EVO3 THETA STOCK Trigger (Red or Black)

Rated 5.00 out of 5 based on 13 customer ratings
(13 customer reviews)




The Theta Stock trigger for the CZ Scorpion EVO 3 provides operational geometry similar to that of the factory trigger, but with a flat face. When compared to a curved trigger, the flat surface profile on our Theta triggers provides a more tactile and consistent trigger pull regardless of where the operator places their finger. The increased repeatability in pull force and trigger movement makes every shot feel just like the last, allowing for quicker and more accurate follow up shots. The Theta triggers are precision machined from billet aluminum available in black or red. Made in the USA, this part counts towards 922R compliance. Trigger includes a new roll pin for seamless installation.

*Please note that for 2016 Scorpion S1 models (pistol/carbine) there is a high rate of welded trigger packs. The retaining weld should be identified and removed prior to any trigger pack work. For more information on removing the weld please see our info here: Scorpion Trigger Pack Weld

    Solid construction, easy to install, flat face feels more natural on the trigger finger. Highly recommended. (Plus the Red looks pretty damn cool! )

    The feel of the trigger is amazing, I have this with the spring kit and its has easily cut the trigger weight by half. Plus it looks way better. Recommend 100%.

    Installed this trigger in about 5 min with the replacment spring kit, AK sefety selector, Theta charging handle, and replacment screw kit. The fit and finish are outstanding, and fit the look and feel of the Evo III very well. The flat face trigger feels much better than the original curved shoe and lets you get a better purchase on it.

    I’m huge fan of flat triggers and this one definitely doesn’t disappoint. Makes shooting the gun so much fun. I initially had problems with the trigger failing to reset and emailed HB, a quick reply helped me discover I needed to make sure the trigger face retaining pin was as flush as can be. The tolerances on this gun are pretty tight so you just need to make sure there’s nothing protruding. After dealing with many gun companies that get customer service wrong… these guys get it so so right. Great product from a great company!

    Just install this trigger along with the the rebuild hardware. Both are as detailed on this site. Really glad I did the trigger job.. Makes for a way better trigger pull than the stock. If I had a do over I would have gotten the 5% trigger. Really like this but for bigger hands I believe the 5% trigger would be perfect! Thanks Guys For All Of The Great products!

    Super easy install if you have any mechanical skills and familiar with lower and trigger assemblies. Great improvement over stock. I got black to keep a stock look. The forward position is much preferable to me.

    Quick Ten minute install no real special tools required! The finish looks amazing! And the difference it makes is great! Combine with spring kit and it’s better then ever!

    Simple installation, much easier to change out than I expected. It’s hard to say how much the trigger helped with perceived pull since I swapped the springs out at the same time as my trigger. Overall 5 stars!
