Not sure where to post this. I picked up a Zenith Z5RS a couple weeks ago and bought a SB Tactical brace for it. I took it out today and with the factory but cap it's 100% reliable. Switch to the brace and it won't cycle the action. The action gets stuck all the way back and I have to to cycle the charging handle. It fires but then it's like the bolt locks open but it has no BHO. With the factory cap it runs great.
Anyone have any ideas on what could be going on? This is my first roller lock gun so I'm not really familiar with them.
