Are AR15 Parts Universal?
One of the main things that makes the AR15 such a popular sporting rifle platform is the fact that it is both versatile and highly modular. Its common pairing with the .223 Remington or 5.56 NATO makes it highly useful for a wide range of sporting and competitive pursuits, and it is a platform that has an extremely large number of interchangeable parts. Many internal and external parts (and AR-15 accessories) while not necessarily universal, are compatible between models.

However, that does not guarantee that a given AR-15 part will fit your specific model, especially since there are so many different types of similar modern sporting rifles in the industry. If you have any questions about parts or cross-compatibility of bolt carrier groups, buffer tubes, triggers, pins, springs, or anything like that, please contact us at 610-250-3960 for more information.
