John it would really help if you would give the length of your barrel, size of gas port or at least length of gas port (pistol, carbine, midlength, intermediate or rifle gas system). Also helps to know what buffer tube your using, rifle or carbine, recoil spring and what buffer. Are you using an adjustable gas block or fixed gas block and do use a suppressor? The actual manufacture of barrel can be helpful as others may know specific information about your particular barrel. Doesn’t hurt to know whether the barrel is chrome moly steel,chrome lined, stainless steel and whether the barrel is Nitride/Melonite. Last info is the specific chamber, SAAMI, Les Baer 264 LBC AR, Model 1 Sales 6.5 Sporter, Grendel II or other varient chamber.
You mentioned you bought two AA extractors but their have been 6.5 Grendel barrels chambered to use 6.5 Grendel bolts with .136 bolt face depth and 7.62X39 with .125 bolt face depth. These bolts are not interchangeable, you need to use the bolt for which your barrel was chambered to use. Normally a 6.5 Grendel extractor can be different than a 7.62X39 extractor.
Many Extractors are supplied with a extractor spring with a stud which holds the extractor spring in place. Many extractors have an O ring around the extractor spring. When you replaced the extractor did you use the stud, spring and O ring?
I had never heard of Hanover Armory so I tried to search for more info on what you might have purchased. I saw a Facebook page with no info and website showed under construction.
