Dakor,
Be carefull to check your trigger latter on as well. I had mine down to 1.5 lbs and had put about 1000 rounds through it before it went off on bolt closing /ubbthreads/images/graemlins/shocked.gif
Fortunately good muzzle control limited damages to the change of underware that I needed! I turned mine back up to near 4 lbs and it hasn't happened again, but once is surely enough when it comes to loud, unexpected booms.
