Frequently Asked Questions
Will this upper fit my existing AR-15 lower receiver?
Yes. This Radical Firearms complete upper is built to MIL-STD (mil-spec) dimensions, which means it is designed to drop onto any standard mil-spec AR-15 lower receiver without modification. Simply pin it to your lower and you're ready to go.
Can I shoot .223 Remington through this 5.56 NATO upper?
Yes. A barrel chambered in 5.56 NATO has a slightly longer leade (throat) than a .223 Remington chamber, making it safe to fire both 5.56 NATO and .223 Remington ammunition. However, shooting 5.56 NATO rounds through a rifle chambered only in .223 Remington is not recommended due to higher pressure levels.
Does this upper come with a bolt carrier group and charging handle?
Radical Firearms complete uppers may or may not include a bolt carrier group (BCG) and charging handle depending on the specific configuration. Please confirm with Goodland Guns whether those components are included with this listing before purchase, as some configurations are sold without them and will require separate purchase of a BCG and charging handle to be fully functional.
