  • M16x1mm Right Hand: For the HK Mark 23 SOCOM.
  • MP5 Thread Protectors: These thread protectors bring "Navy" type MP5 barrels up to spec for use with 3-lug devices, and thus are smooth, not knurled.
    • 1/2-28: Aftermarket MP5-N conversions
    • 1/2-32: Factory HK MP5-N barrels
    • M14x0.75mm: factory HK MP5/40 and MP5/10 barrels

These protectors will tighten down easily onto most any appropriately-threaded pistol or rifle barrel, keeping fine threads from being damaged from bumping around gun cases, or when you're not using your suppressor.

    Ordered MP5 model thread protector,

    Posted by Michael W. on 21st May 2017

    Ordered MP5 model thread protector, got a different part. Talked to Gemtech and there are very few if any of this part number in retail channels. Kept the part instead of going through the hassle of returning it.
