Re: Delrin bushings
About three years ago I ordered SPC uppers with Delrin bushings.
They sent arms with rubber bushings installed AND the delrin bushings loose. It took a minute to install them.
If you get the Delrin bushings, the cross shaft nuts just get turned in to snug. Any tighter and the arms will not move. This is by design. The nuts are lock nuts.
How may I help you?
