In this video I discuss the CZ scorpion EVO 3 S1 and what I like v dislike about this firearm.

This review discusses attachments and upgrades that are vital to the Scorpion. I go over the optic i use, The Holoson 403B, The Magpul Grip and foregrip, The SB tactical folding stock, Magpul magazines and the most important upgrade the gearhead works Safety.

Everyone knows the scorpion bite and the gearhead works safety completely eliminates it. The SB tactical folding brace also makes for a great backpack gun

    For sure... pistol brace, grip, shorter right side safety lever(or mod) and red dot as a minimum. I like the HBI trigger springs and a little polishing to smooth out the trigger as well. Great video 👍
  • Love my EVO S2. First thing I did to mine, since mine came with the SB tactical brace, was get a safety delete for the right side, HB theta trigger, HB trigger spring kit, and a 32 round magpul mags. The HB trigger springs and trigger shoe is ok if your on a budget but if you can afford it, pick up a Timney Trigger for the EVO. It takes your 9lb stock, 5-6lb Pull after HB spring install, down to a 2 3/4-3 3/4 pound pull. It replaces the whole trigger pack so install is easy as can be and takes an amazing PCC even better with that trigger upgrade. Best thing I did to my EVO s2 micro was the Timney trigger and getting a reflex style optic on it, went with the holosun 510c
  • Nice video. You absolutely fire with the stock closed. I have a little over 100 rounds with the stock closed and with no issues. This was in 2 separate range visits.

    I just filed my right hand side safety down about a quarter inch. Works great and it’s free to do. Just need a file or dremal. Love my CZ

    Purchased one for my wife and she loves it. First time out of the box and she was able to group within a palm of the hand 🤚. Very accurate and easy to handle

    Great video! For me, the AK-V mags from PSA work the best with the scorpion.
  • @CQBnerd
    Great info. This video was instrumental with my upgrades. Thank you 💯
  • @markroath98
    Informative video, and well worth the time.

    Instead of cowitnessing you should just throw a hollowed base 1” riser on the holo so you can use the refit or irons whenever you want
  • looks just like my setup but i have a laser/flashlght combo on left side rail.the only isue is getting 9mm ammo to shoot with without spending $35 a box of 20
  • Great review, just add the trigger spring kit . I believe you sold me on the Holosun . Been trying to make up my mind.
  • and I changed out the grip to an apex tactical grip as well as the safety. I can't get the red dot with the 1" riser to sight in. However, when I take the riser off, I'm dead on at 15 yds.

    Excellent just ordered one in odg and abunch of stuff for it lol also subbed up too you
  • @timwalden8291
    Very informative video. Is the foregrip on your CZ Scorpion the Magpul AFG or the Magpul AFG-2 foregrip? Both of them look very similar.
  • @ataz0th218
    HBI makes a safety delete to get rid of the nub hitting your trigger finger
  • @MB42427
    What website you order gun from or was it from local store ?
  • @roninsd38
    I too like Holosun optics, what mount did you use for low profile mount, all of them come with elevated mounts.
