Before I try to find my spare trigger guard pin to check if it will fit, I tried to google if anyone used a trigger guard pin for their gb. My Google Fu came up with nothing.
Is a roll pin for the trigger guard okay for use with a gb? Or is a gb pin different to better handle the heat/temp?
If different, I’ll order a pin from BA.
(I could call BA but based on one person’s experience with BA, Ill get the correct answer here)
Tnx in advance!
I think either would work. A slotted roll pin is not the wrong pin for the application, though.
The slotted spring/roll pin is best for situations with a static load, the coiled spring/roll pin is best for situations with a dynamic load. https://www.spirol.com/library/white...embly_Life.pdf
The gas block application would be more of a static load.

Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee
