TNW Firearms has recently announced that the .22LR version of their Aero Survival Rifle is now available for preorder. This firearm has been chambered in a number of handgun cartridges (9mm, .40S&W, .45ACP, 10mm, and .357SIG), but one of the most iconic survival calibers (the .22LR) has just been added.

The rifle feeds from the Remington Model 597 rimfire rifle magazines. As you can see, the magazine well has a distinctive cutout to be able to accommodate the short 10 round Remington magazine. Obviously, it is also possible to attach the 30 round magazine.

The Aero Survival Rifle is known for its easily removable barrel and quick caliber change capabilities. Because the gun is designed with the upper receiver being the serialized part (legally the firearm), it is possible to convert your ASR carbine into a .22LR one without registering a new firearm. For that purpose, TNW Firearms offers a conversion kit. The latter consists of the .22LR barrel, the lower receiver and trigger group assembly, the .22LR bolt and the magazine.

Right now the .22LR version of Aero Survival Rifle is available for preorder at the MSRP of $799. TNW Firearms will start shipping it around mid-May 2017. The rifle comes with one 10 round magazine and there is also a version with a restrictive state compliant blade-style grip. The conversion kit has a price tag of $390.

    Based on the comments here, I'm wondering if I should buy some cosmoline and preserve my 597 on the basis of being the only apparent one that's ever worked. Took a break-in of about 200 rounds for it to start spamming them out without hiccups, but after that, no problems whatsoever.

    I have an older 597 that shoots great. The metal ten round mags work in it and with a little action/trigger tuning I am happy with it. I've won a few "sporter" club matches with the 597. Just from a standpoint of availability alone I cannot believe TNW chose 597 mags for this, 10/22 mags please.
