“This site contains affiliate links for which I may be compensated” “This site contains affiliate links for which I may be compensated” JJ and Jeff had issues with the Rock River Arms X Series .300 blackout rifle short cycling when shooting our custom subsonic loads. We headed to the range on a rainy day to try the X Series with Defender Ammunition Company's Supersonic 150 Grain and 220 Grain Subsonic .300 AAC Blackout rounds. The Rock River Arms X Series rifle fed smoothly from the ProMag Roller Mag with ARCustoms.com AR Soc and the Hexmag.

We shot off of the Hyskore Ten Ring portable shooting bench... the most consistently used item in our long term review inventory.
