J & J Ceramic barrel
Regulator - Bob Long Torpedo or PPS Stabilizer
New valve spring or clipped stock valve spring
New bolt - Alamo City top-cocking or simply add o-rings to the stock bolt.
Very aesthetically pleasing.
Side-feed for true military look.
Kingman tried to come out with a nice looking military set of markers, but this marker takes the cake as the worst of the bunch. In theory, it is wonderful. Stock board is capable of 25 BPS, side-feed gives it the tactical look, and with a bunch of other military features, the gun itself looks damn pretty. But alas, Kingman FAILED.
The board is nice. Not only that, but it's nigh impossible to damage it. Very nice milling, very durable, and a great look to it. The awesome extras remain awesome, but it's quite obvious this gun was never meant for serious play.
The stock barrel is not too bad, pretty accurate, but extremely loud. There are about five ports at the very end of the barrel to allow air to escape more easily, but unfortunately, it still sounds like an exploding firecracker. Not only that, but the way that the military shroud was milled renders it impossible to use a different barrel system on it (save for the J & J ceramic). And it's unremovable. The shroud houses and protects the valve, and holds the foregrip in place.
The body itself has few flaws. The anodizing on the gun is beautiful; haven't scratched it yet. The screws don't have comparable anodizing, but the effect that the worn away screws have on the military look is tremendous, giving it an aura of genuine vintageness. It is, however, imperceptibly heavy. The double-stacked tube in itself weighs over 2 lbs, making the gun itself nearly four.
I do like the offset feedneck for true rifle-like vision, but the crossbar stock interferes with the rail accomplishing its intended job. Even so, it still fits the standard 3/8" dovetail mount, so you can scope away without having to buy expensive adapters. The detents are kinda weak, but no more so than other Spyder detents.
Now, the operating system itself is the real problem. A high-tensile valve spring prevents the gun from attaining a manageable pressure. The stock pressure is around 850 psi, and without a regulator, this can spike as high as 1000 psi or more. Not only that, but the foregrip housing interferes installing a regulator via bottomline, so you're stuck buying an expensive inline one.
DO NOT LET THE ADVERTISING FOOL YOU. This incredible operating pressure renders the delrin ACS bolt completely ineffective, even after you break it in. It will chop balls no matter what loader you have, no matter how well you time your shots, and regardless of how durable paint you are using. I recommend an Alamo City replacement bolt ($18), or get a machinist to lathe o-rings onto the stock one.
Although the board is nice, it can't save the gun from anything, and despite Kingman's best efforts to introduce an affordable electroblowback military marker, this gun doesn't deserve credit given.
Do not buy this product. Save your money and buy an Ion or a Custom 98. The Spyder MR2 was a gargantuan flawed mechanical design by Kingman, and I would like to see them take some corporate responsibility and try to correct the chopping problem.
