For decades the M16 and later the M4 style “Automatic Rifle” (AR) was the proven mainstay of our military forces and a vast number of law enforcement tactical units, even though the high velocity.223 caliber/5.56 mm bullet it fires is about the same size as a .22 caliber rifle. Then came the invention of the “Weaver” and “Picatinny” rail systems, and it enabled the user to quickly and easily install a plethora of practical defensive attachments to the rifles, so they became even more popular with the military, tactical units and to those interested on personal protection.
However, about three years ago, several firearms manufacturers started marketing .22 caliber M4 style “Automatic Rifles”. This was mainly possible, because the .223 caliber/5.56 mm bullet is about the same size as a .22 caliber bullet. Originally, these rifles were marketed as a low cost practice alternative to the full size .223 caliber/5.56 mm, because the .22 caliber ammunition is much cheaper, and they could utilize the “Weaver” and “Picatinny” rail systems for all the practical defensive attachments as well.
The same reasons that make the new .22 caliber tactical rifle a good practice option for law enforcement also makes them a good practical option for personal home defense.
For example, one of the most practical reasons for choosing one of the new .22 caliber tactical rifles is the fact that any personal defense attachments designed for use on the full size ARs can easily be transferred to the .22 caliber tactical rifles. These attachments include:
One point sling attachment
