    MAG-AD9

    Posted by H Allen Davis on Feb 24th 2022

    I've built several dozen AR platform rifles and pistols over the last decade, many of them as PCCs. I've now built two 9mm AR-15 pistols using the MAG-AD9 adapter, and for my money, it's the absolute best way to go, no doubt. The Stern Defense adapter is far superior to all its competitors, too. The thing is not just well-built, it's rugged in the extreme. Using this adapter in a standard AR-15 lower gives you the flexibility to keep your AR-15 instantly ready for use as a conventional caliber weapon, be it a 5.56mm, .300 BLK., or any other chambering. This is a huge consideration for folks who are limited in only being owning a single AR rifle or pistol. In addition, the last round hold-open is drop-dead reliable, too (and if yours doesn't work, blame the magazine). The MAG-AD9 is the best way to go no matter what, even if you intend to use your weapon as a dedicated 9mm rifle, carbine or pistol.

    purchased with 9mm upper

    Posted by Col.451 on Nov 29th 2021

    Excellent quality and am headed to range this week with it. Pricey but you get what you pay for. Fit and finish superb and the shorty upper is exactly what I've waited for.

    No brainer. If you're unsure of this product then you haven't been paying attention. Buy it. If you buy a dedicated lower it most likely won't have last round hold open
