I have motor mount set for a upscale Flis Tres. This was for a 2 stage project that I just do not have time to work on. The lower motor mount set is for a 4" body tube and the upper rings are for a 3" body tube. The lower mount is 38mm and upper is for 29mm. If you are interested in this set I will sell them for $30.00 including shipping in the US. PM me if interested


That is a much shallower cant angle than the original kit 15 deg. I had to reduce mine to about 11 deg to fit 4 grain motors (54mm).
