mk85

Looking to order a spare breech plug for my new mk-85. The original isn't made anymore, and I don't want to use 209 on this rifle. Was the original breech plug/nipple used for fpj? Also, does anyone know what brand the scope bases are, as I think they take a brand specific ring. Id really like...

I really hate putting this up for sale. Probably my nicest ML. Nikon Prostaff 2-7x32. Sweet trigger. Stainless sling mounts, beautiful bore, Talley rings. $350 shipped.
