It certainly seems that way. Lookit, most spring mods involve doubling the spring, or outright replacement. I don't have the energy to do all your research for you, but stock Nerf springs are typically 2kg to 3kg. So doubling stock springs typically brings a blaster to 4kg to 6kg, which is pretty low on the Nerf power spectrum.

If you're leaving the AR in place, doubling the spring is typically not a problem. I've done it to dozens of blasters and never had a problem. But when you remove the AR, the plunger slams into the bottom of the tube at full speed. You have to balance the strength of the plunger tube with the force of the spring. Some blasters can handle a stronger spring without an AR, and some blasters can't. I suggest reading the internet to figure out which blasters can't.

I'll wager that doubling a Longshot spring with a BBB spring isn't going to be a problem if you leave the AR in place. But as I said before, I haven't done this mod, and many Nerfers have advised against it.

Proceed at your own risk MMan.
