Welcome back to the 8th installment of my blog, in which I don’t claim to be an expert, in fact the very opposite. I’m a new user to the AR platform and want to share my findings and experiences as I go through and build rifles as well as being the Operations Manager at Tyrant Designs.


Today I wanted to touch on the similarities and differences between the AR-10 and AR-15. Many people think the AR-10 is a modified version of the AR-15 but they are wrong, their blood line is weak, and they will never survive the winter! I digress...actually, the AR-10 came first in the 1950's and the AR-15 is modified version of it. Most people note that for a .308 rifle the AR-10 is light in weight by comparison to other similar chambered rifles. This is because the AR-10 uses direct impingement instead of being piston-driven. It also has a aluminum receiver set, adjustable sights, detectable magazine, and a Tyrant Designs pistol grip (I guess you could use other pistol grips but why would you want to?)

This is one of my favorite AR-15 builds of recent

Tyrant Designs AR 15


What's the difference between the AR-10 and AR-15? For starters the AR-15 was designed to be a lighter version of the AR-10 which can carry more rounds because it's chambered in .223 Rem/ 5.56 Nato compared to the heavier .308 Win. Also, the AR-15 has packs less of a punch in terms of recoil which makes follow up shots quick and accurate. Besides the differences in the caliber, the AR-15 generally has smaller components which is why the rifle is lighter. An AR-10 may weigh anywhere from 7 to 9.5 lbs while the AR-15 can weigh 5.5 to 8.5 lbs. Since they have different calibers, some of the parts are NOT interchangeable on both rifles but some parts are. Knowing the differences is very important to your rifle functioning properly.


Tune in next week for Part 2! I will explain in detail which parts are interchangeable and which are not compatible. Isn't this exciting?
