Hello Charles, and congratulations on your recent Galil purchase! I'm Tyler with LuckyGunner and am happy to help answer any questions you got! I have personally used both the Silver, and Golden Bear SP munitions in multiple 7.62x39 firearms I own such as the CMMG Mutant, various AKM's, and Draco-c pistol. All functioned flawless with out a hiccup! If you have any other questions, do not hesitate to ask! That's what we are here for! Happy Shootin'!
