Does what it’s made to do - Maxim Defense Industries JP Silent Captured Spring

I went with the combo including this scs and am glad I did! Skeptical especially for the price I never thought I would get one as the conventional spring/buffer doesn’t bother me but after using one, I am impressed. It is smooth and quiet as advertised. A bonus is that on the build I added it too, for some reason my bolt wouldn’t Lock back with supersonic loads and my metal (DH) magazines but worked fine with my Magpul mags. I tried experimenting from standard , H1 and H2 buffers and since everything worked fine with my Magpul mags, I felt no need to look into further and mess with my gas port etc and called it a day ruled it my metal magazines and just used them accordingly... Well after switching to the Maxim brace and JP SCS “standard” I found that now my bolt locks back even with my metal mags! I don’t know what I’m more happy about, the smoother/quieter operation or it erasing the bolt lock back on DH magazine issue. Regardless I am glad I tried it!
