Best for the $, good build quality (not great), adjustments are difficult. - ADE Advanced Optics 2.5-10x40mm Rifle Scope, 40mm

Purchased this for a takedown 10/22. It comes with necessary hardware to mount it to the factory scope mount that comes with the gun; however, I opted to spend $9 on a picatinny mount for the gun. Mounted great. Had to mount it as far back as possible bc the eye relief is quite short. I would not trust this on my AR bc jumping from target acquisition to long range would be difficult. Consequently, it is perfect for the 22lr. Build quality seems good for a scope this cheap. The laser is not sealed with a rubber O-ring, but the scope itself seems relatively well sealed. The reticle is solid as is the illumination.
Now to zeroing in the dang thing. If it came with directions I wouldn't have gone through 100+ rounds to zero at 50 yards. The adjustments are easy to make, it's just they aren't true for the amount of adjustment stated on the height and there are not markings to specify rt or lf or the amount of adjustment rt to left. In saying that, I was on paper out of the box. She did finally zero with some decent rounds (22's vary soooo much). Note: very experienced with scopes and firearms... Not user error. The laser is as bright as the Crimson trace on one of my handguns (don't expect to see it in sunlight unless looking through the scope at any distance beyond 25 yards). For the $$, it can't be beat at this point. Will see if it holds zero and update if not. 4 stars bc figuring out the adjustments was a pain.
