It's an unbridged barrel, and actually came unbridged stock.

That's just it, I don't want to buy multiple springs to try. I'm just curious if anyone has been able to achieve the near 500 mark with the m130, if not then I'll end up getting an m150 and cutting it down.

I should have been more clear in the original post when I said that I didn't have the parts as they were still in transit. I'm achieving this fps with the stock spring, cylinder, and piston.

Also I'm aware of that rule of thumb and information as well, I just wanted to see if anyone has achieved that fps with this particular spring because it was free, like I mentioned. I don't want to buy and cut a coil if I don't have to. I'll likely just go the washer- spacer route.

That just seems to link me back to the index, but I am fairly certain I know the post you are referring to, I've been searching for someone who has hit 500 with an m130. I think that if I can hit 450 with a stock spring, I can get an m130 to hit 490 at the very least, via washer-spacers. I suppose all I can do is throw the bastard in, and get a real chrono.

Yep that's the one ha ha.

And that's why I thought/hoped, that maybe if I'm hitting 450 with the stock spring, I might be able to hit 500 with only an m130. Only time will tell at this point.
