  1. The one I posted pics of is a 512C. I'll post a pic of the side shortly so you can see the model # on it. The 512C is the aluminum model, the 512T is the titanium model. Not much difference otherwise.
  2. It's my understanding your exact scenario formulated the 512 and the 509.
  3. Coupled with the 509, it may be the perfect short distance carbine optics combo.
  4. My apologies for the poor quality phone pics. Trust me when I say it's clearer than the 510 because it's sealed and purged. 3 reticle choices; 65 MOA Circle, 65 MOA Circle + 2 MOA dot, 2 MOA dot.
  5. PM me an email address and I'll send you a pic of a prototype that I'll be shooting at the Noveske carbine match next week.
  6. If you like that style, wait a few months for the 512c (aluminum) or 512t (titanium). They're sick!
  7. If you haven't taken the battery out, wiped down the inside, then put it back in, try that. Worked for one of mine which was an early version.
  8. Wave spring is the way to go. Shortens the stroke while also reducing the recoil impulse then getting the weight back moving forward as quickly as possible.
  9. Jason Edwards is the only person I know running one on his PCC. Shot with him at 3GN Nationals and shot the gun some following the match. Definitely lightens up the front end. He seemed to be very pleased with it and had no issues with the 4" plates at 100 yards.
  10. Having both a tricked out MPX and a JP, I'd have to recommend the JP if you don't always shoot the exact same ammo. The MPX is more finicky feeding different profile bullets of differing lengths, however, it does have a more manageable recoil impulse. You can really tame the recoil of the JP by going to a cut down 223 recoil spring, all the tungsten weights and stacking 2 wave springs within the SCS. Both are viable options and have won major matches. I'm personally of the opinion that the factory guns are a better/more reliable option than building your own. While shooting PCC at numerous major 3 gun matches over the last 2 years, I have seen very few home builds make it thru a major without serious issues. The factory guns with maybe a different trigger or handguard seem to perform far better.
  11. Best recoil impulse, most trackable reduced dot movement from all the combinations we tried. The blitzkrieg hydraulic buffer with a 308 carbine spring, a spacer and a wave spring was the only other combination we felt was as good or better. No doubt Max did his homework.
  12. I followed Max's recommendation and went with 4 tungsten weights, the lightest 223 spring (white), and then inserted CS100-M11 wave spring in between the white buffer and the back of the SCS. That had the best recoil impulse IMO and runs everything including 115gr subsonic steel challenge ammo.
  13. Ahh, thanks Max. Read the following and just tossed it underneath the whole assembly... If any of you guys have the 9mm JP SCS, you'll want the CS100-M11 to do pretty much the same thing. It did improve the SCS for me a lot. You put it under the plastic bumper at the bottom of the SCS.
  14. No buffer detent used with the SCS. That's how it shipped from the factory.
  15. I would recommend the CS100-M9 as I think it would be easier to assemble/disassemble. It's 1/2" shorter.
  16. I'm telling you, it doesn't work as described in mine or my buddies. The legs on the upper are wider than the gap in the lower in front of the pin. It will go forward 1/4" and then it contacts the narrowing gap in the lower. You can see how it's narrower above the safety. The upper legs will not fit in there.
  17. That works on some guns but not the gmr13 with the billet lower as it gets thinner right after the rear pin...
  18. Compressing the SCS. The weights move fine but then pressing capture rod back enough to clear the rear of the carrier.
  19. Just tried the CS100-M11 behind the JP SCS in my gmr-13... Definitely less dot movement, however, putting the gun together was difficult and I'm not sure how to get it back apart... Any suggestions Max?
  20. I hope you don't feel like you need 8x for a match that doesn't have anything further than 200 yards...
  21. I've had a holosun on my 3gun PCC (JP) for 2 years and it's held up to a number of rounds (5000+), being tossed in barrels, falling on the floor and just general 3gun match shooting.
