hi
youi can get them but i think reflectors are better i was looking for some i think they were about 38mm wide and 35mm deep. which i think is too big for a single led optic.

Just looked on his sight but they are the 28mm ones.
That might be a bit too large. Ill have to do some working on the design. Also I only have a little lathe so I am really limited as to what size of stock I can handle.
