Putting a .50BMG upper onto my bushmaster fixed stock lower. Manufacturers instructions say to remove the bolt stop, buffer and buffer spring.
I have the buffer and spring out. Do I remove the buffer tube to allow the buffer detent to come free?
How do I remove the bolt stop? (Is that the bolt catch?)
