Barrel.

Stern 9mm barrels are ideal for gun lovers who want to build their own custom dedicated 9mm AR15 upper group. Our barrels offer an advantage over the competition. Every stern defense barrel throat is machined deeper for a longer free bore to accommodate bullets with a longer ogive. We have found that some common defense rounds jam into the rifling before the round is fully chambered. Some of the barrels on the market do not accommodate this and will potentially result in nasty malfunctions, resulting in a round being stuck in the chamber requiring manual methods to clear the malfunction.

Note: Barrel comes with locating pin installed.

    Stuff Works!!

    Posted by Troy Taylor on Aug 23rd 2023

    I came into this retrofit project with a "hope it works" strategy. I left with, "This Stuff Works"!! It works great. Very pleased. Ran through my first 100 rounds today after receiving my complete upper earlier in the week, and there were no issues. No feeding issues, no ejection issues, no malfunctions, no bolt hold open issues. Just worked!! Very pleased.

    Very impressed with the quality and function. Tight tolerances, marries to my AR15 lowers with ease. Zero malfunctions after 1,000 round break-in. Awesome. Ordering the pistol sized lower next!

    Stern AD 9 kit

    Posted by Ron Agredano on Aug 29th 2019

    I can review the AD9 conversion kit with complete upper in one word: solid. The adapter went together flawlessly, and was easy with the instructions. The system cycled and functioned smooth with 115 grain and when paired with my other components is going to be a great combo for PCC in my next USPSA/IDPA Match. If you want solid components, buy Stern.
