Tired of being limited on how much time I can spend at the range because of the ammo shortage. I have plenty 22lr to send down range so I was thinking of getting the conversion kit for my AR. Are there any issues using one? Suggestions on brand? Worth it?
The cons to using a caliber conversion are only issues depending on you expectations.
The main issue with using a conversion is the twist rate of your 5.56 barrel is not optimal for 22LR. Typical for 22LR is 1 in 15 or 1 in 16. So the precision of the shot group out of your 1 in 7 to 1 in 9 AR barrel will not be nearly as good as with a Ruger 10/22 or M&P 15-22.
The second issue is that shooting a lot of 22LR will really foul up you gas system, so i would highly recommend ending each session with shooting some .223/5.56 to drive full power gas through the system. This swap is not a big deal but a bit of a nuisance at the range.
So all that to say, I do own a conversion kit but it's been collecting dust for years. I personally prefer dedicated rifle for the caliber as the end results are better.
