I went to zero my Bushmaster's BUIS and the Vortex Spitfire in preparation of 3 gun comps this year and for that purpose, I got a cheap Bushnell spotting scope. The scope was decent for the money, but the tripod was crap:
I ended up blowing all my AE 62 gr 5.56 NATO, to zero and test, but it was worth it in the end:
I love my spitfire:
But I'm thinking of knocking or cutting off the A1 sight. It's in the way.
