I don't know why they are "no good", except for styrene tends to bend. They are the standard Springfields most figures come with. You have many options to replace them though. Top of the list for me is Minie Ball miniatures release of Austrian Lorenz muskets, which is a refreshing alternative. Wolf miniatures has two sets of American Civil War long arms including the Springfield; Shenandoah offers a set of Springfields, and there are more, all of which are much superior(my opinion) to the kit piece. Red Lancers or Sentinel Miniatures or any decent retailer who handles figures will help with acquiring them. Good luck.--Steve Scott
