Hello everyone I have a Element Max in 58cal I bought from a fellow on the forum here it was holding air when I got it but after I filled it, it leaked from the fill port no biggie I contacted Bin and he sent me new check valve parts that took care of the problem no leaks now. So I took it to the range to sight it in for late deer season but my scope wouldn't hold zero so I didn't get to hunt with it, but it was shooting 302gr well for two shots then the scope went haywire. I was originally looking for a .495 50cal because I have slugs and molds for the .495 50, but when Zach contacted me about his 58 I bought it to try out and now if anyone has a 50cal they'd like to trade for the 58 and the slugs I have it would be great, Cheplicki has a couple of videos of when he tested this rifle when he owned it. It's really clean and no problems I'm just wanting one in .495 50cal, comes with everything in the pictures except the bag of 300gr slugs. As you can see it has the barrel band, front pic rail and higher capacity air tank.
