I just bought one of these. I'm going to mount it on a Colt 6721 upper. I know nothing about these things except that they're cool; do you sight it in like a scope (taking off the caps etc) and what does internal adjustment mean? What beginning range should I sight it in at? Any peculair bugs these have I should know about? Thanks..... |
| I believe that the bullet drop lines are measured based upon a 100 yard zero. I zero'd mine at 50 anyway. And yes, it is just like any other scope. Pull the caps off and adjust it with a screwdriver. Just make sure to screw the caps back on tight so that the watertight seal works. |

Here are the USAF 25 Meter M4/TA01NSN sighting instructions, complete with printable target. Seemed to work for me, but I drink enough coffee that 'accuracy' is just another word I can't spell... (ETA: OK, I got lucky this time!  )

Yes, he's crazy. The 'newer' models offer BAC. The NSN offers a finer reticle along with a set of iron night sights. Nothing craptastic about the TA01NSN. (ETA: IMHO, of course.) |
