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.

    9mm Build for 92fs mags

    Posted by Robert S. Allen on Sep 24th 2019

    Used this upper and Mag well adapter to build a 9mm AR platform carbine that takes the mags from my Berretta 92fs. Ran it at the range today and was impressed. Mated it to an Aero Precision lower and only had to change to a 5.4 buffer. I couldn't be happier. Hoping that Stern will develop the same in 45acp.

    Nice parts

    Posted by Kogar on Apr 26th 2019

    Very satisfied with the parts purchased. Looks well built, mag receiver feels robust and designed for the long haul. It didn’t take long to get use to the bypassed mag release button. Installed this on a SOLGW lower receiver. Very east to install, fits perfectly. Very accurate! Tested out to 100yds already. Shot approx 350 rds with no issues yet. Would definitely recommend this to others. Will definitely be building another one with at least a stern BCG and mag receiver. Thanks Stern for a great product!

    Upper kit

    Posted by K the ogre. on Apr 21st 2019

    The build quality is amazing. Great finish looks durable out of the package. Mag receiver is robust and looks like it will last a good while of severe use. I purchased the upgraded bolt and am very satisfied with my investment. I am using a SOLGW lower receiver shot over 350 rounds without a problem. One jam at first, i believe due to not proper adjustment on the set screws. I managed to get it to work with PMags, ProMags, and Glock OEM mags. Ill be doing another one!
