When looking at them from the rear do they still give a completely square sight picture with that front blade? Still easy to hit stuff way out there?
Yep. You can just use the top of the front sight like a "regular" one and get a "regular sight picture". As far as hitting stuff "way out there"? That's up to you...
Ordered it from MidWay but had to pay $4.99 in shipping. Darn thing can't weigh that much. 1/4 the cost of the item on shipping.
Got the green fiber.
Yeah, I think the charges are more due to the size of the padded envelope they ship it in than the weight of the item. Anyway, shipping is always a bummer...I think you will like the green sight fine.
