Hi Ray, when I ordered my Disco I ordered a Leapers 3-9 by 40 AO with it. The scope was very nice, it had mil dot range estimating illuminated recticle, and very clear optics, and only cost me $79.00 here in Canada, so it is probably cheaper by at least $10.00 in the US. I did find the Leapers scope very heavy, and the adjustment turrets were very awkward to use. On my scope I found the adjustment knob almost impossible to seat without the scope clicking off of zero. Maybe I just got a dud scope. I also did not like the fact that the scope could only be adjusted with the assistance of an allen key. If your in the field and happen to knock your scope, (which I happened to do), you won't be able to readjust your scope unless you carry this with you. I replaced the leapers with a Bushnell Banner dusk & dawn 4-12 by 40 AO. It only weighs a fraction of the weight of the Leapers, and can be adjusted without the assistance of any tools. Simply unscrew the turret caps and there's finger knobs to adjust the scope. The optics are super clear as well. It cost me $129.00 at Walmart, so it's a little more that the Leapers, but the added simplicity of this scope is worth every penny. I guess I'm just not one for too many "bells and whistles". There's my 2 cents.
