Does this BCG need any specific buffer weight or anything of that nature? — 3 Answers

9mm PCC's sweet spot BCG + buffer weight combo is 22 - 24 ounces. For FRT and binary functions, I use the KAK industry 4.5 oz BCG weight (replace the 2 oz weight that vame with it), combined with Kynshot hydraulic buffer, and JP polished spring. AR9 goes brrrrrrrrt until the clip is empty. For my semi set up, I removed the BCG weight and use a 10 oz KAW Valley buffer (deadblow effect) + JP polished spring. The ideal PCC buffer + BCG weight combo is 22 - 24 ounces. My setup brings the weight to 22.8 - 23 oz. shoots very smoothly, no bolt bounce, no light primer strike, etc. Just perfect!

It needs a 7.7oz buffer and a 308 carbine buffer spring.
