Things I liked:The Umarex Steel Storm CO2 Gun is for the money the most fun, accurate, & well made air gun! It is extremely accurate when using an appropriate optic (I chose the Walther MRS) and I added a front verticle grip for enhanced stability. The single action mode produces very nice crisp shots and the 6-shot burst mode will put a smile on anyone's face. With 2 fresh CO2 cartridges your first 30 rounds on burst mode will surprise you in two ways, 1) The sound of the gun is much louder than you would expect and 2) the mass of flying steel will destroy a tin can instantly. The ergonomics of the gun are great, the pistol grip is perfect, the rear cocking lever is totally cool, the fact that you can see your 30 shot magazine reduce with every pull of the trigger is also very cool. The shot selector is very positive as well as the safety lever...nice click! Pyramid air totally surpassed my expectations with this gun...When I ordered it, it was on backorder for at least 3 weeks and to my great surprise it shipped the next day. I only paid for UPS ground and got second day Fed Ex air without even asking or paying for it. I WILL NEVER BUY AN AIR GUN FROM ANYONE ELSE...PYRAMID AIR IS AWESOME! Things I would have changed:Not much, maybe the option to buy another magazine because you will run out of CO2 pretty fast with this gun, and they do freeze up in colder weather. This is gun best suited for 60+ degerees (fahrenheit). What others should know:Buy lots of CO2 and BB's from Pyramid air!!! Trust me you'll be amazed at how fast you will go through them with this gun. It's so much fun to shoot that it's very hard to stop. It's also very easy to shoot. My 65 year old mother even gave it a try and was very impressed!
Things I liked:Very easy to adjust the sighting system and very accurate. Brightness settings are outstanding! Things I would have changed:Nothing What others should know:Much better for the Umarex Steel storm than a traditional red dot scope. It's very low profile and is very easy to install, zero and aim with. I give it an A+
