平时我们口中所说的步枪一般是指来复枪或者来福枪又或者线膛枪，而来复枪是指枪膛中有膛线的枪支，是一名名叫来复的美国人在滑膛枪的基础上发展出来的。而从无膛线到有膛线可以说这是步枪的一个质的飞跃，因为膛线的出现从而使步枪准确率，射程以及杀伤力都得到了几何级数的提高。不过现实还有滑膛枪的存在，比如以前香港警队所使用的左轮手枪就是一款经典的滑膛枪。而英国警队至今还在使用滑膛枪。

来复枪是英文rifle的音译，rifle意为枪管中的膛线。从广义上来讲，可以认为凡是具有膛线的枪都可以称作来复枪，包括步枪、手枪、机枪、狙击步枪等等。从狭义上来讲，来复枪多指早期与滑膛枪相对的有膛线后膛装步枪。现在很少再使用这个名字来定义某一个枪种，更多的是做为一些历史比较长部队的荣誉名称来使用，比如英国皇家第XX来复枪团。而霰弹枪其实是一种枪管无膛线的滑膛枪，是从猎枪发展而来的。

来福（又称“来复”）是英语rifle的音译而rifle直译为“膛线”换句话说就是带有膛线的枪，统称“来复”步枪是带膛线的枪支，而霰弹枪是不带膛线的（友情提示，那叫“霰弹枪”而不是“散弹枪”）滑膛枪。但是由于手枪也带有膛线，所以单纯说来复枪指代步枪也不准确。

American gun culture has a long history. It came into being in the early America. In the 16th century, when the initial（最初的） batch（一批） of European immigrants settled in American continent, they often faced with fierce animals’ attacks, conflictions with American Indians and European Powers’ invasions. Under these circumstances, a gun played an increasing important role in defending peoples’ personnel safeties(人生安全). In the Independences War, militias’ decisive contribution strengthened American people’s senses of owning a gun. Militias’ first gunshot in Lexington(莱克星敦) drawn open for Independence War. Since then, according to many Americans, the United States could gain the independence because of every James holding a gun. In Civil War, Abraham Lincoln, American 16th president, encouraged every citizen to possess a gun. Therefore, American people regarded having a gun as an inalienable(不可剥夺的) right. In the provisions of Bill of Right, the second is that every James has the right to holding a gun. It is the legal basis of population of a gun in the USA. So to speak, a gun like hamburgers, hotdogs and rock music has become an indispensable(不可或缺的)part of American culture. 这都是我自己写的，都比较简单。我就省去中文翻译了，希望对你有帮助
