    Super easy to do without tools.

    Having never owned a centerfire MP5, I wasnt sure what to expect.

    Takes 15 seconds. Remove bolt, rotate two pieces. Swap one, rotate back.

    Easy peasy. Like in the video its as easy as adjusting a gas block.

    Fucking awesome.

    The 70* lock with the Eley PCC is magic.

    Shot mine today with 115 FMJ Blazer Brass, 124 FMJ Super Vel certified and 147 FMJ Super Vel 900 fps. This was with the 80* lock piece.

    The 147 was softer compared to my CMMG RDB with hydraulic buffer. Dot barely moved. Easy double to the A zone if you just have a tight hold.

    The 124 has more recoil and the dot moved more.

    The 115s had about the same recoil as the 124s, but the dot moved less.

    My 70 and 60 lock pieces will be here by the weekend. Will be interesting. Looking to chrono different ammo and see what differences there may be.

    BTW, this thing was shooting dead accurate, even with "store bought" ammo.

    Finally installed the SD-G3.
    JP has a proprietary safety so you have to replace the safety to work with the trigger.

    To get the anti walk pins out you need two T8 Torx.

    This is going to be sweet.

    What makes Eley PCC PCC exaclty? Slower powder or something?

    Ive never had any interest in MP5s after shooting (and cleaning) them. The operating system is too weird for me to feel proficient and Im not interested in spending the time to learn the HK MOA. However this JP5 has me needing out on them big time just to learn about locking pieces and timing and whatnot.

    Im not a reloader so Im pretty ignorant on powder burn rates and such.

    Overall its loaded milder. In an 8 MPX it makes just around 125 power factor.

    In a handgun its subminor.

    For example 150 Syntech in an 8 PCC is still around 150 power factor.
