are they easy to set up ie trigger
Trigger was easy for me.
I took out stock spring. Got a old DM7 spring, cut third off and stretched it. Trigger is soo light with no bounce.
First time i took grips off, i was worried, so got Clint from Nexus to show me. Easy once you seen someone do it. I believe there are vids on youtube.
Setting up board is so simple, flick of the dip switch and a few trigger pulls your done.
Study the manual first and maintaining the bolt and HPR will be a breeze. (just watchout you dont cut your fingers when unscrewing the cylinder, the slots are pretty sharp edges)
