Are AR15 Rifle Barrels Interchangeable?
The short answer is no. If you have a mil-spec lower and upper receiver and you want to switch to a new barrel in the same caliber, you should have no problems installing it, regardless of the manufacturer that designed the new barrel. However, you can't switch to a new barrel that takes a different caliber, as your receivers may not be able to handle the new caliber properly.
Can You Put an AR10 Barrel in an AR15?
You should only put gun parts designed for your specific model of firearm into that firearm. Generally, AR10's are designed for larger-caliber rounds that produce a lot of pressure, so they have stronger parts that can withstand the extra energy. While AR15's also handle a lot of pressure, the rounds they fire are usually smaller, so they deal with less energy. This means that even if an AR15 part fits into an AR10 receiver, it may not be designed to withstand the extra pressure. To avoid any issues, only put AR10 parts into AR10 receivers and AR15 parts into AR15 receivers.
