apologies to all who asked for pictures - I actually tried about half a dozen times but it took my son coming home from college to get results…
anyway, these pics show the upper and rail with receiver marks made from charging handle.
there are some marks on the barrel made when removing the handguard cap that have been covered with high temp paint. it never bothered me but looking at the photos, it looks worse than it really is so I decided to not post the pics and will redo it. in the meantime, if you want something specific, PM me and I’ll do my best…
