22 Conversion Kit | The Savannah Arsenal Project

Spoiler:

Zero your .22LR caliber AR15 style rifle, or AR15 with .22LR conversion kit at 25 yards.

From approximately 13 yards out to approximately 89 yards the bullet’s impact will be within +/- 1″ of where you are aiming.

At 100 yards you can expect the bullet to impact between 2″ and 2.5″ below your point-of-aim.

If you don’t have the patience for a detailed explanation, then you will still be well served by the information above. If you want to know more, keep reading.

Why a .22LR Conversion Kit On An AR15 Rifle:

Using either a dedicated .22LR upper receiver or a .22LR conversion kit is a great way to teach a new AR shooter the fundamentals of shooting the rifle without the intimidating loud noise of the full size battle ammunition, and for the experienced shooter to maintain proficiency at a fraction of the cost of shooting full size .223/5.56 ammunition.

To shoot .22LR ammunition out of an AR platform, you basically have two options. You can buy a dedicated upper receiver/barrel set, or buy a .22LR conversion kit that simply replaces your bolt carrier and fires the .22LR bullets through your AR barrel. The dedicated upper’s barrel will usually be a 1 in 12″ twist (as opposed to your AR’s 1 in 7″ or 1 in 9″ twist). The 1 in 12″ twist will result in a better stabilized .22LR bullet in flight which may result in slightly better accuracy. .22LR rounds fired from a conversion kit and through your AR’s barrel may or may not be as accurate as those fired out of a dedicated upper, but I have been very satisfied with the results using the simple and less expensive conversion kit. I can easily hit coke cans at 50 yards, and a full size paper plate at 100 yards. This is good enough for training purposes.

I live and swear by my CMMG brand .22LR conversion kit. When properly maintained, it is both reliable and accurate. They are around $160 and usually come with a 25 round magazine.
