I am starting on a lightweight .243 that I will be using for coyote hunting. I have built several AR15 platforms but this is my first large frame. I am using 18” X Caliber .243 1:10 twist barrel with Rifle length gas port and a adjustable gas block.
But I’m not sure what BCG/Spring system to use. I have my eye on the JP LMOS because It’s only 9oz but not sure the light carrier is enough weight to run the rifle reliably and not sure I can have the best of both world (light and reliable). Also not sure what buffer/spring system to use.
Does anyone have experience with getting the 6mm AR10s to run well? They sound like they are a little more finicky than the AR15s And the parts are spendy when shaving weight so I wanna get it right the first time. I will be shooting suppressed 100% of the time and using lighter weight bullets 55-90gr
