Bad how? I fail to see how a spring can be bad and blow your mechbox.
You mean miss labeled? |
Meaning because they are pretty linear (tighter coils only at the end) they are made stiffer. I've had a bastard of a time installing about half a dozen different PDI 150% springs over the course of the past year. Some are a bit easier (like what i have in my MP5 right now, but am taking out because I'm starting to get fractures in my Hurricane reinforced mechbox) than others, some are impossible to install. Add in the different spring steel used (the impossible ones are a thicker wire and longer) and varying lengths.......... my 150 shoots 350fps in my MP5 with 0.20g BBs, it measures 6 3/8" long, I've had springs on my bench, all PDI 150% that measure all the way up to 7" long. Heck, last Saturday I had to replace the piston in my MP5, took out the spring and have another 150% around as well, put the two together and the other one is about 1/4" shorter than the one I'm using. I've installed PDI 150% springs that shoot upwards of 425fps, others that do 350 or 370fps.
Fact is, I encourage people to buy the Prometheus springs, they are much easier to install and more consistant.
Warphotographer, you don't NEED to install a bearing spring guide, I just suggested it since they are solid, benefit the way your gun works, and will give a bit extra fps. And since the mechbox is open anyways...............
