    MAG-AD9

    Posted by William Palacio on May 25th 2020

    There were 2 of this product one of them is from Stern Defense the MAG-AD9. After much search and compare its product. I found that the Stern was suited for my own liking compare to the other one I was looking into. When I finally received the MAG-AD9 I was impress if the quality that it's made from. I test fitted it I was happy with it glad I bought this from Stern. Great addition to my new AR9.

    Mag Well Adapter - Am I nuts?

    Posted by RoCo on May 15th 2020

    First thoughts after unboxing. This thing costs more than some dedicated lowers. Am I nuts?
    After i popped this into my lower with a specialty trigger, I felt a whole lot better! This thing is real....and I didn't have to buy a new lower, or trigger, etc, etc.
    LRBHO is awesome. Fit and function are perfect.

    MAG-AD9 Mod4 8.5 barrel.

    Posted by Lewis on May 15th 2020

    Received the MAG-AD9 and Mod4 9mm Upper yesterday. Put it on my BCM Pistol lower and ran 100 rounds through it. It was flawless!
    Going to get a designated lower for it so I can leave it assembled.

    Great product

    Posted by Evan Zimmerman on Jan 17th 2020

    Purchased the mag adapter. Dropped right in and works the way it is supposed to. Appears to be built very well. Bolt hold open feature is why I made the decision to purchase over others. Very impressed.
