Very pleased with the build to say the least. Today is day-3 of the MagPul SDM/SPR class and this rifle has delivered out to the 600 yard mark with no problem.
I'm really catching hell at 500 and 600 though due to wind because all I could get prior to class was the Federal Tactical 55gr load which uses the Nosler BT bullet. With the steady wind in the afternoon, I'm really behind the 8-ball at the 500-600 yard mark.
I've got about 400 trouble-free rounds thus far... very happy.
