Magnification range for a general purpose optic on 18" upper

[Klem]

On yours maybe two 2016s instead of the single 2032 might pump the brightness by doubling the voltage. Have not tried that and the idea did not come from them. It is just a thought.

I would be cautious about doubling the voltage on any LED lighting circuit.

I also really like my swfa 3-15 SFP with the diamond reticle. It's no march or NF but it's my favorite scope. It's is leaps and bounds better than my vortex viper pst Gen 2 1-6x. And the reticle is much simpler than my Athlon midas BTR 1-6. It is an excellent scope on my 18".
