Q

BJ612, member, from MN, United States, asked on March 15, 2021

Is this the correct castle nut for Ergo brace adapter model = MPN: 4454?

Expert Answer

A

Answered by Kurt Colbourne, Gear Expert, from IL, United States, on March 24, 2021

You can use this castle nut for that adapter, though some have found the buffer tubes to seat better without a castle nut at all. The adapter uses a set screw so the castle nut is not required.

Q

Tommy, member, from CA, United States, asked on January 17, 2021

How would you stake this castle nut?

Expert Answer

A

Answered by Kurt Colbourne, Gear Expert, from IL, United States, on March 24, 2021

You would stake similar to a standard castle nut. Instead of pushing material into a gap, you would simply push material towards the castle nut. The pressure will lock the castle nut in place.
