Well to my surprise i got my clock cleaned by my son-in-law. He just installed his cmmg conversion kit on his m&p 15t, we tried it out for function and accuracy. It functioned perfectly with all the ammo we tried, then we shot it for accuracy and i was truly surprised. then we got into a friendly competition and started shooting at a medium size bowling pin target. we shot 15 round strings and the first to go out of the pin lost. well i lost first. the only way i could compete was to install my scope and then we were about even steven. I must say the conversion kit was quite inpressive, oh well its hard to beat those young eyes and steadyness.pghrich
