[QUOTE="Profreedomokie, post: 3160107, member: 524"] I built my 300 Whisper from scratch back years ago when JD Jones was the only one selling them. I did all of my own R&D to get it to run. The first thing I would try is replace your buffer spring with one for a 9mm AR. This is for subsonic loads only. After what I learned from my build, I can't understand how a rifle in this caliber could cycle subsonics and supersonics without the fast loads beating it up. If the 9mm spring doesn't help, pull the weights out of your buffer weight and try that. My gun isn't ported like a regular AR , so some of this may or may not work on your gun. The third option would be a light weight bolt carrier. [/QUOTE]
