I put a Mo-Rod on my ranch. With the newer barrel profile on the newer models, I cannot claim to have noticed any real change in accuracy (it shot just fine right out of the box), but the strut makes a big difference in how quickly the barrel cools down. Since I was doing if for that heat sink affect, I went with the Mo-Rod because of those big, complete wrap around aluminum clamps - figured it would be a better heat sink with those.
BTW, the Mo-Rod's newest design clamps fit the tapered barrel profile perfectly.
