I was looking for an inexpensive red dot scope to mount on my AK. Read lots of positive reviews about the Bushnell TRS 25 scope so I decided to purchase one.
The dot is very bright and crisp and I like the fact the brightness adjustment knob is firm and "clicks" with each adjustment this insures it will not move unless you move it, no accidental "on"which insures I wouldn't drain the battery.
The Bushnell TRS-25 Red Dot performed very well during my first time at the range. I shot multiple 3-shot groups at a distance of ~30yards. Zeroing the scope, I found the windage and elevation adjustment to be firm and could detect positive click positions. I adjusted the scope slightly (both windage & elevation) to achieve zero, I was pleasantly pleased it didn't take much to get it zero'd in, approximately nine shoots and I very achieving very tight groups :-). I also set clay pigeons out to 60yards and I was delighted that I could easy pick them off...Love this scope!
Since I was shooting in the early morning facing east with the sun low on the eastern horizon I had the illumination of the red dot set on the "5" power, which was perfect for the light conditions.
I am pleased with the results during my initial outing but time will tell whether this scope can stand up to an AK.
Bottom line, at this point I can recommend this scope especially at $79.00 from Amazon !
