It is hard to break down and buy a .22 caliber AR rifle. Big boys like their toys to go boom, not pop. Unfortunately though, the ammo crunch of 2009 went right into 2010 and we haven’t entirely come out of it. In fact I don’t think we will ever see the price of .223/5.56 ammo come down to where it was. But even at 10 cents a round where you could still buy it back in 2007, regular practice gets expensive pretty fast. To master basic muscle memory you really need to pull the trigger a lot, and without any recoil, muzzle flash and concussion, the .22 makes it easier to develop good shooting habits instead of bad ones.
Armalite just introduced their new .22 caliber M-15 carbine and, as .22 cal ARs go, this one would be for the shooter who takes their AR and their proficiency with their AR seriously. It isn’t a toy that looks and works kind of like your AR. This is your AR that has been re-engineered for the .22 caliber rimfire cartridge instead of the .223 Rem./5.56 Nato cartridge. It has a correct .224 bore, not a .223 bore, so it should be more accurate than a standard AR with a conversion kit for 22LR ammunition. This is a high quality gun for serious shooters. It would be a lifetime purchase as a training rifle or learning rifle for your child. And don’t forget, you can shoot all day for less than $20. Hopefully we’ll be able to do a full review of this gun in the near future. I bet it is a tack driver at 100 yards.
