AR-15 Rifle Scope 4 X 32 Bore Sighting How To ?

Just purchased the OLD SCHOOL top of carry handle mount 4 X 32 Scope for my M-4. Went to the range to have it bore sighted. They looked at me like I was nuts, state, OH, it is too tall of a mount. Does anybody know who or how? Does Lyman have an adapter I could purchase for bore sighting this type of mount? There has to be some way, hell this scope was used for years on Ar-15's and M-16's in the military. After 40 rounds I gave up at the range, could not print the paper at 25 yards. Please help!

Thanks,

A collimating boresighter with an extension will work, I've used them for years. Brownell's should carry them. Otherwise use a laser boresighter.

The old school way is to open your gun and look down the bore. Adjust so you can see a distant bullseye down your barrel, then move your scope turrets to approximately the same place. Get on the paper and adjust at a longer distance.

If you couln't even hit a large piece of paper at 25 yards with 40 rounds, something else is wrong.
