In Lead We Trust MPX Barrel Screws

Be aware their are two different screw head diameters on the mpx. Gen I and early Gen II use a .357 diameter head while later Gen II such as PCC and Copperhead use ~.340. If you have the one piece nut with bar that fits in the left side of receiver you will most likely require the ~.340 screws, if you have the two independent nuts then you will most likely require the .357 screws. Please verify which set you need my measuring the recessed opening on your receiver.
