  1. Cade Prutzman

    Hands down the best bang for buck receiver out there. Every part of it is quality made and assembled, zero malfunctions over 1.2k rounds in. Perfectly gassed and feels like smooth glass to manipulate. I’ll be buying Sionics for all my future builds.

  2. Redacted

    Best upper receiver I’ve ever used. Ive had it for about 2 years and 10,000 rounds and I’ve yet to have a malfunction still. Great warranty for when my barrel gets shot out or anything happens. Sionics over BCM any day.
