CRC 3SF002 | Mini muzzle brake with 1.375×24 HUB thread, 5.56 caliber 

CRC 3SF002 | Minizhaba is a subcompact sound-moderator flash hider with a 1.375×24 HUB thread, designed for use with quick-detach mounting systems, 5.56 mm (AR) caliber.




It features a gas-relief design that preserves reliable weapon cycling without changes to buffers or the gas system and does not increase fouling of internal mechanisms. Compact and lightweight, it helps maintain overall mobility.




The Minizhaba with Hybrid Universal Base (HUB) thread utilizes a widely adopted next-generation universal muzzle thread standard, ensuring compatibility with quick-detach mounting interfaces from various manufacturers.


⚠️ ATTENTION ⚠️
The quick-detach mount is not included. The listed price is for the sound moderator only.




The device is based on a gas-relief sound moderator design developed by the KPYK, which diverts gases to an external contour for flash suppression and sound dispersion. Thanks to 3D-printing technology, the required performance characteristics are achieved through internal structures that are impossible to manufacture using conventional machining methods.


     
 
  • Compatible with automatic fire
    •  
 
  • Night-vision compatible

Material: Inconel 718 offers exceptional durability at high temperatures and is widely used in rocket engines. A key feature of both the material and the design is rapid heat transfer, allowing the device to cool down quickly.


Important: the recommended barrel length for proper operation is 12 inches (31 cm) or longer.
For effective use on shorter barrels, choose CRC 3SF003 Hypnozhaba.

    Choosing the correct furniture

    Why should I choose KPYK?

    KPYK is created in Ukraine and built for Ukrainian operating conditions. Our products have been undergoing real-world testing in harsh climates and combat environments for over 10 years.

    We design our components with the specific platforms widely used in Ukraine in mind.

    KPYK is not just accessories or upgrades — it is a tool adapted to the demanding daily work of the Ukrainian shooter, intended to make it easier, more precise, and more effective.

    How can I check if the furniture fits?

    Each product lists the known compatible firearm platforms. You can sort products by platform or by type of accessory (handguards, stocks, mounts, etc.). If you need clarification regarding a platform or firearm model that is not listed in the compatibility section, feel free to contact us.
     

    We strictly adhere to the Magpul M-LOK and MIL-STD-1913 (Picatinny rail) interface standards to ensure compatibility with both our accessories and third-party products that use these mounting systems, and to give you confidence in their proper function.

    How to install furniture from KPYK?

    Every KPYK product is designed to be installed without any modifications to the firearm’s operating parts, literally “on your knee in a dugout.” Each item comes with the required screws, tools, and an illustrated manual. Video installation guides for every product are also available on our YouTube channel.
     

    KPYK accessories do not require professional gunsmith installation — unless you prefer not to do it yourself. In fact, installation is quite straightforward and feels much like assembling a construction set. Besides significantly improving your firearm, you also get a few minutes of satisfaction putting it together.
     

    All modifications are fully reversible, so if you ever need to return the firearm to its original configuration, you can do so easily and without unnecessary questions from the armory staff :D

    How to order?

    Before placing an order, make sure the selected KPYK product is compatible with your firearm and add it to your cart. Fill in the shipping information and check the email address you provided — you will receive payment details along with step-by-step payment instructions. Complete the payment for your order.
     

    From there, it’s up to us. Your order will be carefully assembled and packed, and whenever possible, shipped on the same day the payment is received. We ship orders on business days, Monday through Friday.
     

    If you need to clarify the status of your order, feel free to reach out.

    What if it breaks? 

    Lost some screws? Noticed some play? Bought a used part that’s incomplete or damaged? No problem!

    KPYK accessories are built to withstand the harshest conditions and keep working — which is why we support our products with professional service.
     

    If the issue is minor — such as a missing screw, a worn small component, or a part that needs replacement — you can order it in the Spare Parts / Repair Kits section, or contact us if you can’t find the required part in the catalog. We will send it to you for easy self-installation.
     

    If the damage is more serious or if the product requires Cerakote refinishing, you can send the item to us by mail. We will service it as quickly as possible and return it to you, so your KPYK upgrade can continue helping you be a more effective shooter.
