Military weapons tend to have to meet higher standards for robustness,reliability, strength, etc. than is typical for firearms meant for the civilian market although one can find plenty that fell well short of such standards. A military weapon, except possiby those meant for use on horseback, is more likely to have a more robust stock that goes closer to being the full length of the weapon. Bayonet lugs are also a feature of military weapons (horse cavalry arms again being a notable exception). Many also have a device that allows for them to be stacked. Adjustable iron sights are also a nearly universal feature. All are designed to take slings and some are designed to use slings of particular sorts or in a particular configuration (such as for horse mounted use). Sights also often have protective ears or hoods on military weapons. Rifle grenade spigots and sights are another military feature. Features to allow the use of contemporarily issued military accessories are also a military feature. The ability to take or use clips is another typically military feature. Essentially, military weapons are designed to be suitable for the manner in which they are to be used in military operations while arms designed for civilians in particular are not, although sometimes features coincide. Of course, it is not uncommon for military weapons to be sold commercially or even to be sold slightly modified to allow that particular variation to be sold exclusively on the civilian market, as we all know.
