    Great value.

    I love my MCK, it turns your pistol into a PCC. They are much more durable than I thought they would be and they look great too. I did have a problem with zeroing one set of flip up sights. My second set of sights on my other pistol and MCK work fine. I maxed out the adjustments and the pistol still is not on target. Two different people have fired the pistol outside of the conversion kit and it is accurate. For some reason we can’t get the sights to work properly. I haven’t contacted CAA yet but everything else is fantastic. The laser works well and the flashlight is excellent, it definitely is good for home defense and will light up everything you need it to. The sling works great and I really like the thumb rests. I thought these conversion kits were a gimmick but I was wrong, they re fantastic and I definitely recommend them. They make anyone very accurate with their pistols.
