  1. McKinley Shifflett (verified owner)

    This slide didn’t disappoint when I unboxed it today, beautiful design with high quality workmanship. My holosun 407k fit perfectly as long as you kept the screws that came with the red dot box. Can’t wait to get the barrel next! Highly recommend! Wish I could post pics to the review. Can’t say enough good stuff about it

  2. Grant Hounsell (verified owner)

    Great slide! Paired with a true precision threaded barrel, Herrington Arms comp, Holosun 507k, dpms recoil system and set on a Icarus Precision XL+ Macro grip module. Has run flawlessly right from the first round! Amazing!
