CZ Scorpion 5.3″ Micro K Barrel

(4 customer reviews)


SKU: N/A Categories: ,


We are proud to offer a 5.3″ replacement barrel assembly for your CZ Scorpion Evo. These barrels have been designed to work in correlation with our Micro/K handguards to reduce your Evo down into the smallest, lightest, and fastest package possible. Our barrels are machined from match grade 4140 Chromoly Steel blanks and finished in black nitride. They are chambered 9×19 and twist rate is 1:10. Choose between a bull barrel with 1/2-28 threads at the muzzle or a light profile barrel with an integrated HK type 3-lug muzzle. Our barrels come installed in a trunnion with the extractor notch machined into them. They are literally drop in ready. Designed and Manufactured completely in USA. 922r Compliant.

Gunsmith installation is recommended on all parts. Please note that this barrel does NOT work with factory polymer handguards (pistol or carbine).

If you are considering using your Evo with dedicated 3-lug we highly recommend our integrated 3-lug barrels because they are fully machined with the lugs recessed from the muzzle by 35mm. This allows you to maintain 5.3″ of rifled bore velocity without having to extend the total length as you might if using a separate 3-lug adapter.

  1. Steve (verified owner)

    Another great product from HBI. The install was straight forward, simple remove and replace. No modification needed.
    Ran 300 rounds of 147g Lawman with out a single issue.

  2. Ken (verified owner)

    The 5.3″ bull barrel replaced a 4.12″ barrel on a EVO 3 S2 Micro.
    I could not get the original barrel to shoot a decent group with a Ti-Rant suppressor: 10+ inches and off the paper flyers at 30 yards.
    The 5.3″ fixed both issues – 2″ group and no flyers with factory ammo at 30 yards / red dot / supported. It gained 60 fps over the factory barrel with AE 147, but still subsonic.
