The ArmaLite 10, also known as the AR10 for short, was developed approximately 30 years before the LR308; yet, it has significantly less market share today. When compared to the LR308, which has a circular cut on the lower right side of the upper receiver before the buffer tube housing, the AR10 has a cut that is angular. This makes it easy to distinguish it from the LR308. The ArmaLite AR-10 is a 7.62×51mm NATO battle rifle designed by Eugene Stoner in the late 1950s and manufactured by ArmaLite. People who aren't familiar with firearms, in general, could confuse the AR10 and the AR15 because they seem very similar. In point of fact, they could even go one step further and characterize the AR15 as a scaled-down version of the AR10. This would be inaccurate as they have major distinct differences from the rounds they shoot, and their overall design and intent.
When contrasting the two rifles visually, the first thing that any observer, no matter how inexperienced, is going to notice is the difference in size. Let us elaborate. The AR10 has a total length of 1.029 meters, which is equivalent to around 42 inches. The length of the barrel is 0.508 meters, which is just shorter than 21 inches. The overall length of the AR15 is 1.006 meters, which is equivalent to 39 inches, and the barrel is 0.508 meters long, which is around 20 inches. You may load either a Winchester.308 round or a normal NATO 7.62mm round into an AR10 rifle. In addition, because of the AR10's calibers' increased mass, they are able to store a greater quantity of kinetic energy, which results in a stronger knocking power.
