In my opinion the Em1 is an undervalued marker to say the least. You can land one of these sweet puppies for as low as $350 if you do some shopping on Ebay (just be careful). I recently purchased mine and am loving every second I play with it. The rate of fire is amazing, the multimodes are fun, and I have yet to break a a paint ball. The marker it self balances well and the trigger pull is amazing. The trigger can also be adjusted, mines pretty damn short. ;) The marker is as simple to maintain as an electro marker can get. Simply an all around quality upgrade.
Almost any marker will need a few upgrades out of the box and the EM1 is no exception. Obviously this marker should only be shot using nitogen or compressed air. If u use CO2 u deserved to be beat up by squirells and imprisoned in thier nut mines, u also dont deserve an EM1. The stock barrel is average like all Kingman stock barrels and could benefit from an upgrade. Dye's are always a good bet, the Freak will get that bore size right and the Armson Stealth is an amazing barrel. The only real complaint I have about the EM1 is the bolt sometimes swells and sticks, perventing the gun from recocking. A minor annoyance and one that can be fixed by upgrading to a swan creek N-bolt! Other upgrades you may want to look into are a drop foward, grips, and a motorized hopper is a must. Another small dis like is the hopper seems to sit very high, the guns vertical profile is huge and can making sqeezing into that bunker a little harder.
Overall great marker for the price. Kingman has constintly put out quality products and this marker is no exception. A great upgrade for anyone looking to play in tounaments and does not feel like shelling out 1000 beans for an angel or black magic autococker. Im not saying an EM1 is equal to an Angel, but for the price the little drop in quality is one I will take, leaves me more money to trick it out. Once again its an overall great marker, I did a lot of research and found I prefered this to the bushmaster as well as the shocker and impulse. I give it a nine because no marker is perfect until u upgrade it.
