  1. 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.
  2. 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
  3. How many rounds before the spring wore out?
  4. 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
  5. 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.
  6. 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
  7. Yep I’ve been trying to follow the same. Once it comes in I will try from 130-160 pf with 115s. I’m using a Jp bolt and short stroke silent capture spring. Which I think should be solid... I’ll play with the ammo before I start messing with weights in the buffer. I have to ask, what powder are you using and what do you suggest. I’m running titegroup as of now.
  8. You can’t post this data without saying what powder you’re using... otherwise it doesn’t mean much. I get ~100+ FPS more out of 14.5” with 115 and titegroup
  9. I’m on this next shipment for Brekke 12”. It’s going on a full gmr build so it’s got a ton of weight behind the upper. I think this may help absorb it along with the short stroke silent capture. With the 4” comp, you’re saying it’s possible to drive the comp a bit. Is this the way to go now? Just up the powder charge till it doesn’t move? Or just go for the lightest loads?
  10. That seems like a really iffy design where the gas ports onto the CF shield and through the top of the handguard where your hand might go
  11. Yep fully agree. Only was making the case of merit in lightening up the front end. There’s a bunch of different ways to accomplish that If handguard is what you want a cf is the way to go, if shroud then so be it! Sent from my iPhone using Tapatalk
  12. Smoke composites for sure. I understand the mental unrest that comes with looking at the price. Lightening up the front end actually may help you shoot better as your transition speed may be drastically improved. Now for most people that probably won't be the case. I'm coming from a full 14.5" JP Gmr upper which ways an astronomical amount. I've done experimenting with supper light uppers and transitions and immediately ordered a brekke upper with the CF handguard. PCC and open in my opinion are the most gear determinant divisions as the upper levels are super close in time and points.
  13. GZCLP, super versatile and scalable to different levels.
  14. Yep, it's a two fold problem. First is to move your feet and body correctly. The second is being ready to shoot. I agree, watching football players and other shooters is a great way to understand what's happening. One of my favorite shooters especially for movement is Lesgar Speedy Murdock. This man is an absolute legend for movement. I was able to watch him shoot at the last A6 and the level of efficiency is insane. Check him out on instagram and slow down his videos to see exactly what and when he is doing.
  15. Been throwing this around with my buddy for awhile. I'm not confident with my routine yet. Usually match morning I have a tiny amount of coffee, then during the match it's a lot of water and a gatorade. The part I'm unsure about is a redbull, which I'll have around stage 1-3. Without a doubt, I can feel a difference once the redbull is down. Sometimes I'm more focused, and sometimes I'm mentally foggy. The major issue for me, is being out in the Florida sun for 5 hours. Also I'm sprinting like I mean it. I often find that the last two stages I am physically exhausted, which is why I've been doing the redbull. This is obviously not the right way to solve this problem. Physical health and maintenance at the match is something that I need to work on... giant sun hat, fan, or umbrella, and little chair.
