I ordered a silencerco saker 762 for my grendel and my ar-15. I have a Precision firearms neptune VIII upper with a 20" fluted Bartlein 1 in 8 twist black nitrided barrel on a bushmaster lower with magpul m93A2 stock. Im still learning so please go easy on my lack of knowledge. Im assuming my stock is using a carbine buffer and spring. How do I know which size gas block to order ex..750 etc? How do I figure out what size gas system I currently have rifle, mid, etc? I believe my grendel is over gassed cause the bolt slams pretty hard and recoil seems harder than my ar-15. So do I need to get an h2 buffer also or will the adjustable gas block be enough to tame recoil for suppressed or unsuppressed? Any help is greatly appreciated.
