Things I liked:A relatively cheap sight that performs well. I like the postiive click adjusters for windage and elevation. This isn't a high-tech sight for top-level target shooting matches, but it does give you a quantum leap in performance over most standard (non-aperture) sights fitted to air rifles. Things I would have changed:It would be nice to have a more solid mounting system to connect the sight to the receiver dovetails. What others should know:The paint finish is glossy, so you need to either keep the rubber eye-cup attached and shove your eyeball right up to it, or put some sort of non-reflective coating around the aperture. I just used soot from a flame.
Things I liked:Accuracy. I use these pellets for 10 meter target shooiting, plinking and hunting. My rifle loves them! They are good out to 40-50 yards. They shoot very tight groups, so it is really hard to justify using cheaper but less accurate ammo. Things I would have changed:The tin needs a screw-on lid - it is inevitable that you will spill pellets because the lod doesn't stay on. The price - but I guess you pay for accuracy. What others should know:Transfer these H&N Sport pellets into a different container or tin. The Crow Magnum hollow-point design works quite well as a wad-cutter for paper targets, leaving a nice clean hole.
Things I liked:The price is right! If you're interested in 10 meter air rifle target shooting, then this front sight tunnel and ring insert make a perfect combination to use with a dipoter rear sight. Things I would have changed:At this cheap price, I wouldn't change anything. Making changes would push the price up. What others should know:The included ring sight insert is for circular targets. If you want to plink at anything other than circular targets, you'll need to get a post insert and use that instead. You may want to use an exacto knife to trim off some of the plastic flashing from the moulding seams.
