This is my Tactical 20 that Mike M. built the upper on a few years back. It is like shooting a laser and the accuracy is phenomenal. Learning to make the bras was a hoot and I am shooting DANZAC coated Sierra BK's.
I used a 3 pound Timney trigger, a few extra goodies like a Magpul trigger guard and a Wilson bolt release and an enlarged selector. I found the ACE Skeleton stock to work well in the field and I swap the lower over for IPSC 3 Gun matches. Scope is a 6X18 by Nikon and I have found it on par with anything else I have used in my long shooting career.
Here it is on an outing after PD's in northern Arizona.
