I am planning to change the gas block on my shorty (11.5") Ar-15, and was wondering if it is tough to "do-it-yourself". Is it only a matter of removing all three spring pins and slide the block out of the barrel or is it more complicated than that?
Is there anything else I should be aware of before the swap?
All information will be greatly appreciated,
