Wholesale sports in Nanaimo had the Bushnell Micro dots, and the Bushnell ACOG clones at my last visit.
I was very keen on one of the micros, until I played with it a bit. The dot is just too small for these old eyes to pick up smoothly, and the dot "smeared" into an out of round blob at some brightness settings.
So instead, I bought the NEW Gen 2 Bushnell "T" dot ACOG clone. Bigger, heavier, but so far I like it as it is VERY fast to pick up that crisp clean "T" reticle.
AR 15.com has athread on the Gen 1 version of these scopes, and aside form a large percentage of these scopes coming with the "T" reticle set off index at an angle from vertical, the reviews were mostly positive.
I had mine at the Victoria gunshow last weekend, installed as far forward as possible. the far forward mount, with both eyes open, works best for me for fast work.
as usual,
