I purchased a 1/2-20 DonnyFL adapter for my Benjamin Marauder rifle. The adapter does not have an o-ring on it, but the end cap of the Marauder does. Do I need to transfer that o-ring to the adapter? If I do, the adapter does not tighten flush to the barrel shroud - the o-ring doesn’t go all the way in like it does on the original end cap. Not sure what I’m supposed to do…
Thanks!
