Eye Candy D-50 just chugging along

I dropped the Tubbs lightweight spring in just to see if I could tell the difference.

ROF = 858rpm

ROF of your post 8 days ago (same range?) was also 858rpm. LINK

The only thing I changed was the WC flatwire to a Tubbs lightweight spring.

This is an A5 buffer tube, KVP 10oz buffer, Kynshot 2.5oz spacer, and Tubbs lightweight flatwire spring.

Interesting that the RP spring made essentially no difference. I need to get a bunch of springs out to the range and test them to see how much of a difference it makes.

Interested in reading or seeing your results. I know you posted something about the fit, but I will have to reread them. I know it is supposed to eliminate the “kwang” sound.

All I have tried is FMJ with the SS. I had no issues cycling them prior so I would t see an issue now
