It works, but isn’t necessary - Strike Industries AR-10 Flat Wire Spring

I ordered this due to cycling issues on my Aero M5 build. Turned out I needed to open up the gas port on the barrel. Generally 308 ARs are overgassed, not undergassed. This model seems too long for either carbine or rifle length tube. Again it works, but I ended up trimming a couple inches off to make it easier to put in my carbine length tube. My rifle cycles flawlessly.
