I have a Burris FastFire 3 I use principly as a secondary optic on one of my AR, mounted at 45 degrees offset. I am working on a SBR build and am going to use the FF3 as the primary optic temporarily until I get a T1 clone. I dont want to spend much on this mounting cofiguartion as its temporary, so I am going to buy an el cheapo 3 slot riser mount and mount the FF3 to that via the 1913 base. Which height would I want to get? I dont have irons yet but if I do get them I will want lower 1/3 cowitness. The riser mounts come in 1/2 inch, .83 inch, and one inch heights.
Thanks |

5/8" is about right. 1/2 is too low (dot is in the top edge of the window), and 0.83 is too high.
Best bet is to spend the $$ for the Burris AR mount with wings. Sorry. The only other route is to get the 1/2", the get one of the two speed bead spacer plates and some custom longer screws. Thats how mine currently sits, it was cheaper than the burris mount, but obviously a bit of a pain to find the parts, particularly the screws. |
