How to Install A2 (M16 style) Buffer Tube and Stock
A better tip than using a spray gun oil is to use grease. Seriously just pick up some bearing grease and some nitrile gloves. You definitely want to use grease on your buffer and buffer tube because you don’t want to get a face full of oil when you first fire also, you don’t wanna ruin your clothes.
