Frequently Asked Questions
Will this stock fit my AR-15?
Yes, if your AR-15 has a mil-spec buffer tube, this stock will mount directly. Mil-spec is the standard across most commercial and military-pattern AR platforms.
What's the difference between G.I. style and other AR stocks?
G.I. style refers to the original military rifle profile—a fixed, non-adjustable design. It's simpler and lighter than modular adjustable stocks, with a proven track record. If you don't need length-of-pull adjustment, G.I. pattern stocks are no-fuss and reliable.
What's included in the package?
You receive the stock itself. It installs onto an existing mil-spec buffer tube assembly on your lower receiver.
