I got a TAPCO A2 Front Sight Adjustment Tool on my Key Ring, it goes with me, every time I leave the house. I got it at my LGS for only $7 New. I would suggest you check out these links. I'm sure you will find what you need. http://www.midwayusa.com/product/304696/dpms-front-sight-adjusting-tool-4-prong-ar-15-a2-steel http://www.midwayusa.com/product/816450/tapco-front-sight-adjusting-tool-4-prong-ar-15-a2-steel http://www.midwayusa.com/product/259955/troy-industries-battle-sight-adjustment-tool-ar-15 http://www.primaryarms.com/Tapco_AR15_M16_Front_Sight_Tool_p/tintool0902.htm http://www.brownells.com/gunsmith-tools-supplies/sight-scope-installation-tools/sight-adjusting-tools/ar-15-m16-sight-wrenches-prod333.aspx |

I think he means for installing an A2 FSB in perfect vertical relation to the rear sight plane. I've seen jigs for it but no commercially available tools. I eyeball mine.

Thanks 303 Enfield - quite an interesting and useful tool.
My issue is to align clamp-on A2 front sights to the receiver and make sure it id perpendicular and not canted to one side (I have no machining skills or tooling). |

Clamp your rifle in your work bench vise, hang a plumb bob across the garage from it, use your Mark Two Model Zero calibrated eye to align the FSB. Easy peasy.

My home-brew method if you don't have a vice is to use a table or in my case, kitchen counter. I'd mount the barrel on the upper receiver and tighten the clamp-on FSB enough so you can still make adjustment. Then flip the upper & FSB upside down. Once the ears of the FSB and the sight channel of the upper rest flat on the surface, then you can tighten the hex screws to really tighten the FSB in place. Then you can use your rear sight and FS post to aim at a plum vertical line (e.g. corner of a room where two walls meet) to double check the alignment.
