i just got in a pretty nice hammers T-dot red-dot type optic sight. so far so good. the sight has very clear and sharp optics for it's very reasonable price. the switch/intenseity turret is a much larger and more conventional type than the guide gear ACOG rip-off. and seems much more durable and sturdy. after the horror of that GG garbage coming apart in my hands i turned all the hammers turrets a few times in each direction to make sure they were attached proper. so far their all still holding up.
the T-dot comes with 5 settings green and 5 settings red. with a fine dot in the middle of the "T" so far i like it!
IF it will zero and stay zeroed this could be a budget type winner.
i did have to order a offset mount for it for the AR-flattops which adds to the price a bit. i ordered it direct from hammers and the shipping was only $2 USPS!
when the mount comes in i'll give it a try on the 5.45x39er hopefully it will Co-witness with my BUIS.
