Started out about 12 months ago with a Wells, modded that until I got around 300 fps. Then tried the all-metal build. Put one together from AS parts with a few Wells parts to make it work, got consistent 400 fps. Accuracy over any distance not great though. Hop-ups will fix that, they said. Tried two different ones, no difference or even worse. So thought I’d go back to putting together a “better” Wells from the 3 I’d bought and all the parts I’d accumulated. Nylon receiver, nylon gearbox, with the usual mods. Ended up with a nice light, reasonably accurate blaster that would do consistent 300+.
Then I saw the Alpha Kings. I like the M4 platform, but boy, they did look nice. So I get the “goldilocks size” one. Not too big, not too small, the 74MS. Low Guido gets a 105, it does 280 out of the box, metal gears, shimmed, 1.3 spring, etc. This should be good I thought, maybe just do some cosmetic mods.
So, after finally getting the battery in, what does the chrono say? 220’s to 240! And that’s when the magazine is actually feeding gels Put it back in the box and went to the beer fridge.
Next day I pull it apart. I find a spring that is 1.2 to 1.25 thickness, and pretty ordinary on the spring dyno. The bevel gear shaft seems to have taken a liking to it’s bearing - it doesn’t want to part from it But it seems to spin quite freely so I put it back in for now. Put another 1.25 spring in that’s about 5% stronger than the stock one. Try it again, 270 to 280. Now have to find a magazine that works consistently. Others have had this mag feeding problem with these too.
It reminded me of the post from @calcifer in the “what makes better blasters” thread where he described how these things get built. I think Low Guido got the one put together by someone who knew what they were doing. Mine was done by grandma after a few rice wines.
