Huntsman22,
Did you compete in a PR event with the RAP and MDT-LSS? How did it perform?
I competed in one event with the plastic stock and 4 round mag and had lots of issues with FTF!
I am installing the LSS to build a respectable system to compete with my friends... As soon as I get my Timney installed & modified safety I should be ready to give it a go on 3/28...
I get 1/2" to 3/8" groups with the 6.5 Winchester 140match ammo.
What ammo are you using? Have you considered a hand load?
