I have been tryin to get the rivet out of the gas tube so I can release the stock handguard and replace it with the steel ventilated one. I have clamped it in a vice and used a tapered punch and hammer to punch it out but that is not working. Ive tried a couple other ways but am having no luck...it will not budge. Any tips or ideas on how I can get this out? Thanks in advance
