Submitted By: Randy L. On 06/30/2012I just purchased this 450 upper from Hinterland on the 26th of june and had it on the 29th. Great service!
First thing I did was to check it out for operation, then cleaned it and oiled it up. Started by installing a Redfield revenge 3 to 9. the mount was the Burris Ar-P.E.P.R 1".
Next I bore sighted it to the scope at 50 yards then fired two shoots the bullets touched.
Made one more adjustment to the scope, in the X, moved to 100 yards fired 2 shots 1" group
made the final adjustment 3 shots 1.5 high above the x 1'' group.
Moved the target to 200 yards fired 3 more shots just amazing 1 1/4 '' group.
The lower is a DPMS with a timney trigger and I was shooting from a lead sled rifle rest.
People if you want a 450 upper this is the one for you.
I do recommend you do the trigger job you will be able to shoot just like I did.
