Description
Easily Convert Your Lower to 9mm
There's no need to go with a pistol-caliber specific AR lower on your next pistol-caliber carbine build. Simply add the Stern Defense AR-15 9mm Conversion Adapter and use either Glock or Smith & Wesson M&P pistol magazines with ease.
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.
- Made of aircraft grade aluminum
- Lightweight, ergonomic design
- Installs in seconds
If you’re considering converting your AR-15 to a 9mm, give the Stern Defense Adapter a thought!
