I replaced the FLGR with a stock recoil plug, spring guide, and 16 lb spring. I took it ot the range and it fired with out any malfunctions.
Two parameters changed: the buffer effect and the FLGR effect, and two results were observed. No malfunctions and shoots to the right. Is there a more specific correlation?
My theorem: solid FLGR might restore POI and eliminate malfunction.
Thanks,
