I tested my AMD-65 today,I dont have headspace guages so I took it to Ohio Rapid Fire and had them check it.They said I did a good job on the build,made me feel good..Anyways they said I was ready to rock -n-roll.So off to the range which is paper and no rapid fire.I just shot strictly to test the fuction and for fun, no accuracy.Sure puts the fireball out,and louder than hell the recoil isnt much I guess due to the brake.She worked perfectly :rockin:.Do you guys ever get that weird scary feeling when ya first fire a rifle ya built.Cant explain it but it is freaky..(I guess it fadesw/experience)I figured since the headspace was ok what could go wrong.So the first build was a success YEAAAAAA!
