One of these is not like the other…
Mark Philip Lichtenstein used the photo above in his article that appeared in my Medium Digest.
Since nearly his entire article is misleading or incorrect, the photo doesn’t surprise me.
The top gun and the cartridges are .223/5.56. The lower one isn’t.
The top gun is a Ruger AR-556 MPR which is a semi-automatic rifle chambered for the .223 Remington/5.56x45 NATO cartridge. “MPR” stands for “Magpul Rifle” because it is equipped with a Magpul pistol grip and a Magpul collapsible stock.
Why does it have a collapsible stock? To allow the pull length, or the distance from the middle of the trigger to the rear of the butt, to be adjusted for shooters with differing arm lengths. Contrary to the hype spread by the ill-informed, it doesn’t make the rifle particularly concealable. Even with the stock collapsed all the way, the rifle is still almost three feet long.
The submachine gun-looking firearm in the photo is actually an Umarex H&K MP5 S-A semi-automatic rifle chambered for .22 Long Rifle rimfire ammunition. It’s discontinued but they were made by Walther in Germany for Umarex. It’s a replica of a H&K MP5. The thing on the front is a fake suppressor.
Scary? Not so much. The magazine is slotted, so the little .22LR cartridges are easily visible.
The truth is that the two guns are quite different, both in caliber and intended use. The Ruger can be used for home defense, hunting certain types of game, feral pig control, competition and target shooting. The Umarex is suited for target shooting, plinking and rodent control on farms and ranches. It’s also a pretty good conversation starter at a shooting range. They’re inexpensive and a they’re a hoot to shoot. Almost zero recoil and .22 ammo is cheap, too.
How do I know this? My younger son owns one.
