American Tactical Imports Omni Hybrid Stripped AR-15 Lower Receiver Multi-Caliber Reinforced Polymer

The Walther PPK/S 22 blends the iconic PPK design with the fun and
economy of the 22 long rifle. It is identical to its legendary PPK
brother (which is chambered in 380 ACP), however you can shoot the 22
rimfire for pennies a round and recoil is nominal. The German-made
PPK/S is a double-action semi-auto with a 3.35-inch barrel, a 10+1
capacity, fixed sights, and a black finish with black polymer grips.
It has the typically-heavy (17+ pound) Walther D/A trigger, however
S/A is light & crisp. Standard features include a
safety/decocker, windage-adjustable rear sights, and a
suppressor-ready barrel threaded 1/2×28 . The PPK/S 22 makes an
ideal first firearm for a young shooter, or just a fun plinker to add
to your own collection.
