Things I liked: Comes with the adapter
What others should know: On the initial fill, plan on about an hour to let it cool every 5 minutes or so. I weigh around 165 and I can forget about controlled pumping after 2200psi. It is more like I have to get on my toes, lunge in the air and force it all the way down quickly. It may say 3600 psi, but you'd better be a big ole boy to do it. The good news, there is no reason to go past 3000 anyway. I get maybe 10 shots with 43.2gn Eun Jins at power 10.0 to drop the tank down to 2500 or so. Figure on 5 minutes to go from 2500 back to 3000, probably 50+ pumps, and sweat will be there. It is a "fun" way to work out. I do believe it is the exact same pump that has the Benjamin label, but it comes with the AF adapter. As others have stated, I used loctite on the handle and base plate screws before I ever used it. It doesn't appear to be greased which could be normal, but I don't know, time will tell.
Things I liked: Power and accuracy are great. On power 10, 43.2 Eunjins are exiting at 915 fps@ 200bar with a ragged hole at 25yds-30yds opening up around 1/2 inch at 40yds.
Things I would have changed: The crummy trigger shoe being plastic sucks. It really makes an otherwise great looking gun very cheap. Also, the machine work on the threaded barrel gets a big minus from me. Whoever cut the threads apparently didn't look at them to notice that the whole center section is stripped off from balling. At first I wanted to return it but I'm easy going. Also, the "flash hider" is aluminum and has a place for a set screw- but no set screw! Whoever is subcontracting this muzzle work needs a good smack!
What others should know: The trigger is not what I would call crisp. It is a little spongy, but it is a hunting gun not a target gun so it may take I little bit of getting used to. Just be prepared to feel a little creep before the hammer drops. This may get better after it breaks in.
Things I liked: They do exactly what I want from a 25 caliber air rifle, they deliver some serious wallop. Out of my Condor, at power level 10, they are exiting right at 915 fps (80 foot lbs. of energy) and I have proven that they will completely pass through a coyote skull (25 yard side shot). The accuracy is there too, I assume most shooters should be able to keep them around 3/4" or so at 50 yards.
Things I would have changed: I would like to buy them in bulk of around 500 or so.
What others should know: I have noticed that at least one of my shots had the pellet impact the paper sideways. The power was maxed out though at 13 on the Condor. It must have been either supersonic or just too much air trying to blast past the skirt upon exit. Even at power 10, you will be pumping up the tank frequently. It lost about 2 fps every shot and I guess about 100 to 150 psi every shot as well.
