Good but not to hype - Strike Industries AR Carbine Flat Wire Spring

I purchased this to replace my old worn spring in my duty M4 and it did make it difference from the old spring but not as advertised. The worn spring made less twanging than this and in my opinion it was way louder. I would say the felt recoil was a bit softer than before. It’s not trash but it definitely under delivered. Strike Industries over hyped this buffer spring.
