  1. Wes – Curated Arms

    I have not shot this BCG yet, but will for sure. I got to get an education on it and inspect and handle it at Shot Show 2023. I have never held or seen a BCG of this quality and smoothness of operation. I can’t want to get them running in my rifles!

  2. Zack

    This is simply the most well-crafted BCG I have ever used or seen. I have been running the SHIP out of this thing. ZERO issues and everything just wipes off when you are done shooting. I can’t wait to see more of what Icon comes out with.
