The Stern Defense AR-15 9mm Conversion Adapter is easily installed into any mil-spec AR-15 lower receiver within seconds and even incorporates a last-round bolt hold open feature. Each adapter is machined from aluminum and requires the use of a 9mm/.40 S&W barrel and a Glock-cut bolt.

If you’re considering converting your AR-15 to a 9mm, give the Stern Defense Adapter a thought!
