CMMG Echo .22 LR AR-15 Conversion Kit (25 Round Mag)

The CMMG Drop In .22 LR AR-15 Conversion Kit is what you need to turn your AR-15 rifle into a plinking machine. This conversion kit converts a standard .223 Remington or 5.56 NATO chambered AR-15 into .22 Long Rifle, allowing you to practice without spending a fortune at the range. The magazine holds 25 rounds of ammunition. For best performance use a round style hammer as notched hammers can cause function issues and 36 grain plated nose bullets have proven to be the best choice for function.
