The JP Enterprises Gen 2 Silent Captured Buffer Spring System that I would recommend for your build is the heavier H2 version MPN:JPSCS2-15H2. This model will allow for proper functionality of your 300 Blackout pistol which will require a heavier buffer system especially because it will be suppressed.

Even w pistol length gas system, I'd run carbine (normal, not added weight) BC subsonic 300 does not like to cycle well
