I wouldn't have thought so, I've accidentally sizzled my finger on the end of it not paying attention while getting up from a prone position with an immoblizer on my ankle. Then I saw that one and thought maybe they used some type of high temp. paint. I hoped they weren't so I wouldn't feel obligated to paint mine. I knew the Stg58 wasn't but my L1A1 has been through the ringer and figured there was a chance it may have worn off over the years. Glad I won't feel like I need to paint mine after all!!
