Can switch between calibers, so you don't have to buy multiple firearms. http://www.gunsandtactics.com/desert-tech-mdr-the-new-bullpup-benchmark Relatively lightweight (under 8 pounds) which is one of the reasons I sold my AWC G2A (it weight 12 pounds with scope and heavy barrel). Good trigger (3 to 4 pounds). MSRP will be $2100 to $2600 depending on configuration. No word that I can find on what it costs to get the different barrels. Takes standard mags (AR, SR25), no word that I have found on which mag it will take for 7.62x39 - AK mag would be really nice as they are cheap, plentiful and very reliable. This could replace multiple rifles in a personal defense armory: FN-FAL, AK, AR, Tavor, AUG, etc.
