Huge improvement unsuppressed - Manticore Arms Tavor Gasketed Port Cover For Iwi Tavor

Autistic ramblings ahead:
First lets talk about installation. No instructions included, so before you strip things, DO NOT TOUCH THE SCREWS BEHIND THE PORT COVER. the cover simply slides out once you lift the rear high enough to clear the stock. The rest of the installation is straight forward.
I'm fairly new at shooting suppressed, so I'm learning that starting a session with the silencer attached can be disappointing - until you take it off and see just how much work the can was doing. Same thing here- Suppressed, the Tavor is still gassy enough to sting the eyes, I think it's all coming out of the active ejection port. But taking the can off, I noticed a huge difference over stock. I never shot the Tavor suppressed before I put the gasketed cover on, but lots of unsuppressed shooting.
Overall, it's great! Knocked one star for my own expectations, but marketing leads one to believe it is great for suppressed shooting - it's not.
