I had a scope rail put on the Ruger Mini-14 which completely replaces the heat disapator and let me get away from the side saddle mount. Sweet set-up with the holo-sight for what is essentially a short range light barreled gun.

The problem was that the gun started cycling VERY poorly. First round chambered and sometimes the 2nd round but I couldn't get thru a 5 round factory clip never mind a 20!!

The guys at the gun store said I had to use .223 and NOT 5.56 ammo. I was under the impression it was the same thing but they say a 5.56 in a longer round. ( not Caliber ). They cleaned and lubed it and said it worked great. ( It WAS clean )

Does anyone know if thats fact or fiction?? Gonna hit the range this after and it had better burn thru a 20 round clip with NO problems!!!

I want to make sure it works before I bury it for when they come for all our guns.
