Most tubes will go in too far. Only by a single turn at most though. Not the case for the OP. One of many examples I’ve read/experienced. http s://www.ar15.com/forums/ar-15/Buffer_Tube_Screwed_in_too_far/66-453989/
The tube it too long on the threaded end, it’s out of spec or for a different firearm. You can use the slide/2 pin method or send it back. Installing a new tube would void warranty unless you get it in writing from Arms East that it doesn’t. Good luck!
Let me rephrase... You can't thread a tube in too far when the buffer retainer is where it's supposed to be.... That's a completely different issue being discussed in that thread
