Questions & Answers
Will these fit the Maxim Defense 9mm JPSC?

No the maxim uses a shorter spring. You can order those online from jprifles, it's the extra short alternative spring pack

Product Info for JP Enterprises SCS System Alternative Spring Pack - 3 pcs

The Auxiliary Spring Rate Kit for the 9MM line of JP Silent Captured Springs allows custom tuning of the device to a given rifle and ammo. While the default spring installed in the JPSCS is selected to offer the best performance for the widest range of configurations, a simple disassembly and reassembly of the JPSCS with a slightly different spring rate can yield truly optimized performance.image

In selecting a spring for your rifle, install a heavier spring if you feel the buffer head fully compress and bottom out while firing the weapon. If the bolt will not lock back reliably on the last round fired, select a lighter spring.
