Just got back from doing a 3-day (fairly locally) SPR/DMR course with Magpul. It wasn't what I was expecting initially, and that was a good thing. Fantastic training and I lucked out in having a small group in the class (6), so lots of individual attention when needed. My Noveske 18" LW just chugged away with zero problems and stayed accurate throughout the course, even when we started shooting a "higher" volume of fire (for a SPR). I was a little worried about the LW barrel having issues as it heated up, but it continued to stay more accurate than me. Highly recommend it, for those interested. Here's a pic of the instructor (on the gun) playing with his weapon as we were finishing up with a drill (and student looking on).
