Things I liked: Im like the gun and the way it shoots, it hits hard a little hard to control but im getting it. The little washer and breach seal fell out and I had to put it back in hope it stays so far it is. The finish on the gun is good I wish they would just put a clear on the wood I just striped all the dark finish off my old model 36 and put clear on it, I realy like the real light color finish. Im not sure whats going on here but I shoot my 350 magnum from my up stairs window to a target 30 yards away also taking out some pesky sparrows. It will shoot dead on, then il put the gun away go to shoot it the next day and its off buy an inch or 2, everythings tight so I zero the scope back in and im fine. Ask BB he thinks mabe a temp change of 30 degrees or more may be the problem but I dont see that being the problem. I still only have about 300 shots though it so mabe it will get better in time?

Things I would have changed: Not much R W S makes a great gun I was looking for a more powerful gun and I got it. Only thing I would change is the finish mabe it a nice light color finish, mabe Il strip this one to this winter? and im still not sure how to that lubercating needle in where u lube the spring and piston, the cocking arm is in the way? I hate to have to remove it each time I have to lube it.

What others should know: It is a little hard to shoot and it has the power and recoil to go with it but once you learn it, its fun to shoot enjoy the power it has it. Ive been shooting premiers 10.50 gr in it to break it in after that im going to shoot the J B S 10.34 ot see what that dose.

Things I liked: My wife bought me this gun as a gift about 6 years ago, so mine doesn't have the T05 trigger. I would have bought it .22 version if I'd had the choice. That said, the .177 shoots a very flat trajectory which is useful in the field. It still packs a big punch, and penetrates very well. The ergonomics on this air rifle are excellent, given a brief break-in period (for your arm as well as the gun). Once you get used to it you can shoot hundreds of pellets in a plinking session. You will need a 10.5 grain pellet for accuracy. I like the H&N barracudas. You will also need the weaver scope mount made by RWS, or your scope will creep from the recoil. This gun can break a cheap scope (mine did) so get a good one. Accuracy is excellent once you learn the artillery hold. You need to keep your hand (or something soft) between the gun and any solid rest you put it on, or the gun will jump from the recoil before the pellet leaves the barrel.

Things I would have changed: I have heard that Umarex is offering upgrade kits for some of its guns. Is there one for this model? I would love to see a gas spring conversion kit that I could have installed at PA. I know that this would probably void the warrantee but it might be worth it.

What others should know: I have had to replace the mainspring and seals in this gun three times. The first time I just cleaned the barrel with bore oil, a big no-no. The next time I put too much of RWS' own chamber oil into the gun, and it made a sound like a .22 long. Someone needs to explain how to oil this gun properly. The third time the pellet I was using simply had some oily residue on it right out of the box, and the gun dieseled on me. Be very careful to keep oil out of the compression chamber and barrel of this air rifle. RWS will cover the cost of fixing the gun but not the cost of shipping to its headquarters in AK.

Things I liked: Style of the stock. The wood shines up well. Cleans up good. The barrel is solid.

Things I would have changed: I'd probably only put a marking somewhere that we could see to know what model exactly we have. Thats it. Nothing big, its the perfect rifle.

What others should know: Its got somw weight to it. Its not a light weight little air gun that smaller kids would need to be trying to use yet. Its sot some "meat" to it so to speak!
