Things I liked:Rock solid base. Very well manufactured. It not only has a lip on the front that you can see in the picture, but also a stop pin in the rear in order to help with the second springer recoil. Things I would have changed:Nada What others should know:I bought the medium rings to go with it, but feel they are too high. If I had to do it over again I'd definitely use the low rings. I have a 40mm scope and it sits way up high. Other reviews said that there was some obstruction that made the medium rings necessary, but now that I have it installed I can not understand what they are referring to.
Things I liked:Very well made - hold tight. What others should know:I bought these to go with the UTG RWS Base. These rings are too high. I wish I would have bought the low profile rings. I have a 40mm scope and there is more than enough room to use the low mounts.
Things I liked:I think they have tiny magnets in the tips. With my RWS 94 at 10 yds a 5 round group goes into the same hole. Not a ragged hole or a clover leaf mind you, but the SAME hole! Things I would have changed:The tin they come in. I've learned that it makes me very unhappy to spill 500 pellets on the floor. I save my old Crosman tins and photocopy the label from these tins. Glue the new label on top and I'm happy again.
Things I liked:I love the way it clicks into place while cocking. Cocking and firing cycle is very smooth. Accuracy is good. Things I would have changed:Trigger is bad. Scope is bad. What others should know:Mine was detonating terribly when I got it. I took it apart to clean it and found that the piston seal was torn. Pyramyd and Crosmand were great and sent me a new seal with no questions asked. Accuracy is good as stated above, but it is very hold sensitive. I definitely have to concentrate to keep the groups small. The trigger was terrible so I bought an aftermarket blade. It definitely improved things and now I can feel a second stage. The new trigger blade did not, however, turn it into a Rekord, so manage your expectations if you decide to do it. Bottom line is that I am now a believer in gas pistons, but I'll probably look into getting one that's less powerful so that it's not so hold sensitive.
