Frequently Asked Questions

How can I tell if my AR-15 style rifle is an M16?

Not all AR-15 style rifles with carry handles are M16s. The M16 is a military select-fire rifle. Civilian variants, like the Colt AR-15 Model SP1, are semi-automatic. Look for markings on the lower receiver that explicitly state 'AR-15' and the specific model, such as 'SP1'.

What are the key differences between an AR-15 and an M16?

The primary difference lies in their intended use and fire control. The M16 is a military rifle capable of select-fire (semi-automatic and fully automatic). The AR-15, particularly civilian models like the Colt AR-15 Model SP1, is semi-automatic only. While parts can be interchangeable, their legal classification and function differ.

What does 'CAL. .223' on a rifle receiver mean?

'CAL. .223' indicates the caliber the rifle is chambered for, which is .223 Remington. This is a common caliber for AR-15 style rifles. It's important to note that while .223 Remington and 5.56x45mm NATO cartridges are similar, using the correct ammunition for your rifle's specified caliber is crucial for safe operation.

Are rifles with carry handles always M16s?

No, rifles with carry handles are not always M16s. Many civilian AR-15 variants, especially older or retro-style models like the Colt AR-15 Model SP1, feature carry handles. The M16 is a military designation, while AR-15 refers to the civilian platform. Always check the receiver markings for definitive identification.
