Best Bore Sighter for M1A and AR15

[loadedround]

I have an interesting question for all you milspec shooters (and others). What is the best type of laser bore scope to buy for zeroing in your M1A's or Ar15's with a mounted scope, The universal type that fits the muzzle or the the type you drop into the breech. As you know the Bushnell bore sighter is useless with a muzzle brake/flash hider and a high mounted scope. Even that extension to raises the boresighter itself doen't work well. I want the best one to get on paper in the shortest time. Thanks.

Forget the boresighter; just shoot the gun at 25yds. and dial it in.

The AR is easily boresighted by removing the BCG from the upper and simply looking down the bore.

Easy to bore-sight an AR by just looking through the hole.

An M1A would be a simple matter to just shoot at close range, measure the POI, and do the math to finger out how many clicks you need to move it to the aiming point.

Should only take three shots to get as close as you would get with a fancy laser bore sighter.
