Buy it in a six pack, one wont last a day of play.
Its strengths include, frankly, very little. More about this later on.
Terrible build quality, More on this later.
When I think Kingman, I generally thing low-end entry level markers, its what they have always done in a consistent and good manor. This Mr4, as it is called, is a terrible excuse for a marker. When I saw how the bolt is also the cocking knob, I had hope, as the old spyders used this setup, and was hoping maybe the build quality had returned, but I was wrong.
Build quality(Or lack thereof.): First Looks.
Under a mediocre milsim stlye coating, you will find a purebred piece of scat not word the name Kingman. Anywhere it was possible, its injection molded, where its not, it looks more like cast metal than anything. The valve stem looks very weak, and the cupseal was begining to deform after a single 200 round hopper.(200 .50 cal paintballs that is.) The hammer on this one was not finished, and had a number of burs down in the oring groove, which in turn shredded orings very quickly.
Test firing the Mr4:
After a look into this marker, we decided it was time to shoot it. Keep in mind that this was a brand new MR4, never used, just unboxed earlier that day. Topping off a 13ci tank for use with this(To test some of the mythical better efficiency theories.) we ventured out behind the shop with 200 rounds of Premium grade .50. I was not shocked to see this had zero accuracy after about 30 feet of travel downrange upon firing, I was, however, surprised when I saw that is velocity was a hair over 370 FPS. Knowing high FPS can create erratic paint flight, we chronoed it down to a usable 300. This took a while because of major fluctuations in the FPS, sometimes 30-50 FPS variances. Eventually we had it working, at 300 FPS, we averaged a flight distance of about 1/2 to 3/4 that of a .68 caliber marker at the same FPS, again, I was not surprised. What really surpirsed me was that by the end of the test, the cocking knob had bent itself forward, because when the marker recocked, it slammed into the back of the body from overpressure in the valve. But by this time the test had ended thanks to the cupseal deforming so far it leaked badly.
Returning inside, we degassed and took the paint out of the marker, cleaned the breach of gobs of paint(Yes, it chopped a number of times.) and started taking it apart. It took a while to get the bent cocking knob out, and then the rest of the dis-assembly wasnt to hard. I was shocked to find, after 200 shots, that the hammer had a nice amount of wear on it, and the sear was already dulled, this may have been the way it came, I do not know, I didnt check the sear before firing. The valve cupseal was trashed, Ive never seen something like this from a brand new marker.
Steer clear of this marker, Steer clear of .50 caliber. The smoke Milsim GI tried to blow up everyone's ass is utterly and entirely false. If you have a brain in your head you will not fall for it.
Dispute: I do not believe his reviews are accurate due to the fact that the Spyder Mr4 is not a .50 caliber marker and he keeps referring to using .50 cal paint.. if this is the case, he would by all means run into trouble continually--though this would not accurately reflect the quality of the gun. Other than that, from the sounds of it, he used it way too far on igh velocity--and then complained the equipment did not function well... using it at such high velocity for more than just a shot or two (to adjust) will most definitely cause some damage and thus--performance issues with the gun.
Good detail he provided but not exactly how the product should be represented to someone if they take care of it properly (anyone can damage or misuse (putting .50 cal paint in a .68 cal marker) a marker and it will NOT perform properly ;) )
