Today we're looking at one of the earlier books printed by Collector Grade, Thomas Dugelby's Modern Military Bullpup Rifles. It's a good resource on the EM-2 rifle (and others), but unfortunately is very much out of print. You can find a couple exorbitantly priced copies on Amazon, but beyond that you'll have to watch eBay and gun shows if you want to find it. http://www.forgottenweapons.com/book-review-modern-military-bullpup-rifles
