Got out the new BCM upper a couple times now and it runs great. Did a bunch of one ups today and it's smooth as silk with hammered pairs. Was quick transitioning from 25 yeards to steel at a 100. Had a Holosun 510c on it and love that reticle and field of view. If I had younger eyes I'd be tempted to run an eotech...but without my glasses on the reticle is so fuzzy to the point of being unusable.
Also had the Steiner 1-4 out and am really pleased with it. Very clear glass, great light transfer and I love the red dot. I'm going to need to work with it more up close...I'm slower with it and threw a couple shots.
