Things I liked: Quiet. Puts 14.3 grain pellets out there at 900 plus fps with litttle more than a click. Until they hit something. Great trigger once sorted out. Accuracy settles in after a couple hundred rounds. The sense of quality of the parts is very high. The thing balances on the hand grip so handling the considerable weight is very good.
Things I would have changed: The manual is a joke. The conditions for the "lifetime warranty" are absurd. Who is going to send one of these things to UK every two years for a grease job? For $180 plus shipping? Add a power adjuster.
What others should know: Looks like one has to expect some teething issues with this one. It's well worth the fussing around to sort things out IMHO. This is an utterly fantastic air gun once you know how to drive it and much cheaper than other exotics. Be sure to use the 10% off coupon! As received, the trigger was as bad as a Chinese Gamo copy. It took a few hours of guessing and trying on the adjustments to get it where it should have been from the factory. But it got there. Accuracy was terrible at first: 2" groups at 10 yards!! I was ready to send the thing back. It finally got down to 1/4-3/8" after 200 rounds or so. There is no recoil so it was not a matter of managing a gigantic spring's thrashing. It takes 220 strokes of a hand pump to pressurize the big bottle and you get about 70-80 full power shots. No leaks, though. Came with nice soft case, but PA didn't put it in a plastic bag for shipping and it showed up a little dirty from sliding around in the shipping box. Looks like the Webley group is taking over Logun so the website is useless for now. Other info suggests Webley is not much concerned with quality control. I understand this gun is made in Bosnia. I can't guarantee this paragraph! It is extremely important to be sure to get the hang of the bolt with its latch. Works great, but it's different. "Supa speed" it's not. Once the magazine is inserted, one MUST pull the bolt all the way back and push all the way forward firmly until it latches to avoid feeding problems. Do this, and it feeds all pellet types just fine, thanks. If feed doesn't work right, pull the bolt back to it's hold open position and drop the magazine out. You can tell if it has misfed, index back to an empty chamber, etc., as necessary. Good arrangement, actually.
Things I liked: Look, feel, trigger, accuracy, price.
Things I would have changed: The o ring at the tip of the valve buried deep inside. This was the source of the leaks in both of my guns.
What others should know: If you can work on things, these are a great bargain. If not, avoid the hassles. Both of mine leaked within a couple of hundred rounds. I replaced the valve o ring with a no. 006 and the pump o ring with a 116 and both guns have been happy since. Trigger problems seem to be caused by the springs inside the grip together with burrs on parts in there that can actually cut through the springs. Again, if you don't like working on mechanical stuff, avoid this gun!!
Things I liked: The idea.
Things I would have changed: The sample I received had knife sharp corners where O rings have to slide past. Not good. I have a lathe so could fix it. Needs a way to keep liquid CO2 out of the gun.
What others should know: It looks like liquid CO2 will run into the gun and plug things up so pellets barely exit the barrel. Keep the muzzle level or slighly raised and it's mostly OK, but not great. Definitely store the gun vertical. When it's working, muzzle velocity is about 620 fps with RWS Hobbies. Most will go through a single hole at 10 meters with the occasional flyer. A remote set up a la paintball would likely be much more reliable and feed just the gas into the gun.
