I don't post much, but the P&F is a pretty scare topic around here.... I have a Pride and Folwer RR 1-4, and I have used a Horus reticule before. I like both. I picked up the PFI RR 1-4 on the EE prior to ever using one (great deal and a leap of faith). I personally give the Pride and Folwer RR 1-4 a 9.0/10.
The reticule is very quick.
The BDC is accurate to 600 when I have tested it with M855.
The glass is very good quality from Japan.
There is no fish eye and it is no more than a 1.1 - 4X
The scope is built IMHO of similar quality of a scope in the price range.
Takes CR-2025 batteries (I think that's the nomenclature, but it is the same ones as the T1 and the sunto watch... commonality FTW)
The daylight illumination can washout in direct sunlight against a light color background
There is no cat-tail made for it.
