| Looking to order the 512 to put on a flat top Bushmaster and am curious as to whether i should put a riser under it to ensure the dot clears the fixed front sight. If so a specific model riser recommendation would be appreciated. |

Quoted:
It depends on whether you want to 1/3 co-witness or absolute co-witness your red dot. I like absolute, so I use no riser. This, I prefer the 1/3 co-witness for Aimpoints but if using an eotech I prefer not to use a riser. As of right now there is a 512 on my LMT with no riser and KAC 300m rear site. |

I prefer a riser for a lower 1/3 cowitness for my 512. Less sight picture interference and more comfortable cheek weld to boot. I prefer the the LaRue mount... simple and SOLID.
I'd recommend checking out an Aimpoint T-1 before you order the 512 though. I own both, and I liek them both, but as I discovered in a recent Carbine class, for ME, teh T-1 was faster, easier to use, lighter... just BETTER. YMMV, but you owe it to yourself to check it out. I used to be a total EOTech fanboy until I used them side by side in the class. |

No riser here, no problems. |

No riser, and I use a GG&G accucam QD mount. http://i192.photobucket.com/albums/z96/M4builder/ARFCOM/A15.jpg Same here. However, when using a red dot the shooter should be focusing on the target & not the dot to begin with. Therefore it doesn't matter that the FSP is "in the way" because it will become a ghost image or shadow which shouldn't affect your sight picture. |

If I'm not mistaken, its having the BUIS visible and lining up in the lower 1/3 of the field of view through the red dot sight. |

If so a specific model riser recommendation would be appreciated. I prefer using my EOTechs with the LaRue EOTech mount. It puts the front sight in the lower 1/3 and gives you quick detach capability with absolute return to zero. |
