Quoted:
What size drill rod will fit down an AR-15 barrel (5.56)? I want to use it to make sure my suppressor is aligned properly. I'm looking for a drill rod that is the maximum size that will fit. Remove magazine from rifle, check chamber, if loaded unload with rifle pointed in a safe direction. Remove upper from lower, then remove BCG & charging handle. Attach suppressor to upper, look down bbl. If you see any obstruction, you have an issue, if there's nothing but daylight you're GTG. You're complicating an easy task. Unless you have an unknown brand bbl. If you go the drill rod route, it needs to fit real snug. Any movement throws you off. |

I bought it second hand and I believe someone cut down a 16in barrel to 10in and took off the markings with the excess barrel. I have looked down the barrel with the suppressor attached and the hole is nice and round but the suppressor appears closer to the bore on one side compared to the other. It's a .30 cal can on a 5.56 gun so I have a little extra wiggle room, I just want to make sure the path of the bullet isn't too close to the endcap/baffles. |

CNC warrior sells a bore alignment rod, they cost $14 ea I bought a .30 and a .223. They have a slight step in them so that they sit on the crown. Only issue I have is the with the oversized portion of the .30 cal rod wont fit in my AAC 762SD. The blast baffle is tighter then the rest of the baffles and wont allow the rod to pass through it. |

Sounds like a M-1A flash hider alignment tool. You have a friend with a lathe? drop the blast baffle area down a tad and should work. |

If you aren't happy with the KISS method of looking down the barrel, then for a 30cal can on a 5.56 barrel, just take a standard cleaning rod and use it. Most smaller cleaning rods are just under .22 caliber and are going to give you an "about right" confirmation that you aren't off so grossly that you have to worry about a baffle strike.
