Source of good springfeed spring?

[The Inflicted]

I'm interested in converting my KP2 to springfeed.
Does anyone know of a good place to source the necessary springs of the correct length these days?

Depends on the length. The 20 rd rap4 stick mags for their stbb pistol would probably be the best. For a 10ish rd mag, DAM, Spyder or dmag springs would probably do it.

MCS should have what you need. They sell springs for 10 and 20 round mags that would work well. Just make sure they're roundball springs and not FSR springs when ordering.

Dye mags aren't a terrible option

Well look at that ,I was wondering the same thing.

If I recall correctly (MCB v2)... you can DIY with piano wire, a dowel, pliers, a spacer of sorts, and a drill.

You can make your own springs? Mind blown 🤯

How many you need I got about 6 or so of the Dye Mag stock mag springs you can have for shipping cost if you want. I could probably just throw them in a padded envelope because they are in Dmag protective tubes.

My local shop offers Dmag springs lots of guys change out the springs on the Dam mags to Dmag springs to shoot regular paint better (they are lighter). I use to change them out when I built DamHammers. I think I got some left.

Palmer's? They converted mine to spring feed.

What was the cost?

I spent about 700 getting everything done that I wanted, but that included re-tubing the barrel, adding a sight rail and a ball detent, RVA, dropout for the 12g, Fasst change knob, new pump handle, valve, rebuild, quick strip, and the feed. It's very playable now!

Palmers has these listed:

Spring Feed Spring – Palmers Pursuit Shop

These may be long enough:

DMAG Standard Feed Spring, 30 Round (2 parts) – MCS (mcsus.com)

The magazine springs I ordered from MSCUS arrived.
The 14-round DMAG springs are approximately 7.5 inches long at rest and the 20-round springs are 14.5.
These appear to be about the same strength as the spring in my old RAP4 Firestorm magazine but it's closer to 30 inches long.
