Finally read the FAQs

Finally read the FAQs (3/11)

  1. Big question I have is: Can you confirm that it is a proprietary upper+lower system and not compatible with gmr15 lowers?
  2. Can't decide on this or the czechmate... Honestly, if this doesn't have mag reliability issues, then it will be an amazing option.
  3. Kind of an odd request but I'm out in Boulder for the summer for work, couldn't bring any gear with me unfortunately. Anyone with an extra rig going to the Pike's Peak USPSA match next month who's willing to help out an experienced shooter? Would need... everything but will happily cover the ammo expense and loading tax obviously. Competed in Area 6 twice and various other level 2 matches so no worries on the experience front... want to get some USPSA matches down while I'm out here! Let me know if you can help, thanks guys!
  4. I just received my 12.5" Brekke custom upper. so much much much lighter than the heavy JP. I haven't shot it yet but I definitely think it's going to be an important switch. Most people are going towards medium weight setups now. Not ultra light nor heavy. I see the benefit of lightening up the front end. I cannot stress this enough, for PCC you already split fast enough, but where you'll win the matches is in transitions and movement. Both benefit from the lighter barrel. The dot movement at least in theory can be cleaned up with mount, stance, load development, and buffer system.
  5. To answer your question, first, the JP is worth the money if you are looking for a fully built tuned set up. I would recommend getting the shroud barrel and not the 14" or 16" full length. However, the full length has very very good recoil management. The MBX is okay too but there's not much to say about it. But also consider DaVinci Arms for their prebuilt options. Second, I would definitely not recommend the MPX as even the gen3 does not have enough precedent for the high round counts of uspsa... though you'll always find that one guy who basically want to f*#k their MPX they love it so much. Now, ck1 has a good point in saying that MaxL has insane performance out of cheap gear. I would also recommend following some of his builds. He has a few builds posted on here and insta where he uses a FM9 bolt etc. I would probably go with a JP lower receiver due to the importance of glock mag angle and then follow a Max or Hwansik build from there. PCC is very equipment geared and there is complicated topics involving short stroking, bolt speed, trigger performance, and barrel weight. It's a very complicated field which is why unless you follow a professionals build exactly (a good option) or have an experienced friend to help, I would probably recommend doing prebuilt.
  6. https://imgur.com/a/dVSpZyq Apologies Sarge, this is a photo of the bottom of my primer plunger. Just a single small allen key slot I think it is tightening the spring captured base.
  7. on the 650, the bottom of the spring, there is a tiny allen key. I'm not sure what it is for other than capturing the spring. The picture posted above, underneath the spring and the bottom black piece. I just don't know what it's for exactly. I'll send a picture in a few days when I can.
  8. Understood! so what exactly does the tiny allen key do? Is it to capture the spring?
  9. Hmmm. I am interested in that. The gold nut tightens the primer tray or does the tiny Allen key on the spring plunger tighten it?
  10. I have the flat faced jp competition trigger in my gmr. I can attest the 3.5 pull and the trigger freeze... I've been looking for a solution but its frustrating as the good hair triggers like the elfmann etc are not at all reliable for pcc. I think the forceful reset of the trigger that max leograndis talks about is super important but I still think it'd be great to get a hair trigger that offers that in a pcc.
  11. To get my primers seated properly I need to push with an insane amount of force. Like way too hard for the normal action of reloading, which is why I think something else is off in the tolerances... shell plate or assembly etc
  12. How many rounds before the spring wore out?
  13. That is fine and all... but the reputation is not flawless. Which is why you don’t see everyone shooting them. It’s not the price. That said yes the recoil is insane with the sig. If you could get them to run reliably with 20k rounds before spring and minor replacements, then it will be a viable choice
  14. Yes I found this out the hard way as well. The shell plate tolerance has a huge effect on the primer seating. Thing must be pretty snug then really really minorly backed off. Went and ordered the 650 grand slam upgrade kit. And I hope that will take some slack out of the system.
  15. I’m having the same high primer issue with my 650. Please do NOT reseat the primers on the live rounds! Set those aside for training. Prime an empty case, mess with a few things and reprime it harder. Keep in mind the primer should not be flat with the bottom of the case but recessed into the bottom
