  1. 2 things you should try. 1. Use thicker size battery. Duracell or Panasonic is thicker side I believe. Since DPP is not a screw down battery cap like SRO (DPP = a locking cap), when using thinner size 2032 battery can cause issues. 2. Use Dielectric Grease on the battery. You can just rub it around to thin coat the battery and it helps to have more consistent battery conductivity. This is what I use: https://www.amazon.com/Permatex-81150-Dielectric-Tune-Up-Grease/dp/B000AL2RI2/ref=sr_1_5?crid=1DT8SXVBSUBWS&dchild=1&keywords=dielectric+grease&qid=1603418574&sprefix=dielect%2Caps%2C252&sr=8-5 If there is no improvement, gotta send the optic in to fix.
  2. I own JP, a personal built with Taccom stuff (barrel, buffer, and bolt), and a build that's a copy of Max Leograndis' set up. Now I have 2 pcc that's a copy of Max's. I love it, it shoots the best out of all the pcc I have tried so far. I recommend you check out his build from his insta. (Brekke Custom sells the barrel and handguard). The parts I used to copy his build are 12"+4" comp Brekke custom barrel+comp and their Max handguard QC 10 lower (FM9 for back up) Hiperfire Eclipse trigger (competition trigger in the back up gun) Kynshot 5015HD buffer with their SS spacer JP 308 carbine spring 5 quarters in the tube Welded bolt (Taccom bolt in the back up) Anderson upper (same as Max) K2+ grip
  3. Is the Rom 3 max working good so far on your slide? Who did you choose to get your slide milled?
  4. 40 dollars? I didn't know that. I thought It'd be more like $100 to do that. I have no experience in getting one done so far.
  5. Black looks sexy! I just ordered the brass grip myself. I might try using black sharpie for the "coating" lol
  6. I have heard 5015HD is solid. I shot many round thru it runs w.o any issues so far.
  7. I am using Clean shot. Here is my load data. This is my current load powder weight OAL power factor RMR 115JHP Clean Shot 4.2 1.100 141 This is my old load. EV 115JHP Clean Shot 4 1.080 135 I have JP bolt and SSCS too. I don't use them but I can say the load I use may not be the best for your buffer system. I couldn't get the JP buffer setup as good as my current setup. The current setup cycles so much faster due to extreme short stroke. I like how the red dot comes back to zero super fast. End of the line, I would say as long as the dot comes back to zero for the second shot consistently without too much effort, it should be good to go.
  8. I was referring pulling the handguard in to the shoulder (chest) as push pull.
  9. You can check out Max leograndis' insta. He did some vids on his setup. I basically copied his build and ammo setup as close to his. I have tried 95gr, 115, 124, 147 loads from 130-160pf range. I find 115gr 140pf works the best for 12" brekke setup. Depends on your buffer setup and powder, I believe the ideal load may change.
  10. I have spent too much money tinkering to get the gun run reliable and good recoil. I settled with Brekke 12" with their 4" vertical comp, Kynshot 5015HD with their SS spacer, JP 308 carbine spring, 5 or 6 quarters in the buffer tube, and a welded Bolt (Taccom Extreme bolt works too). This way, I am short stroking a lot. It's been very reliable and the best recoil. I can shoot all As at 25 yards with .13 splits. I don't need to push pull much either compared to muzzle breaks. With vertical comp, the gun comes back down automatically. For this, I have to make sure to use lighter bullets (115 or 124) to produce enough gas. I currently use 115gr at 140pf.
  11. I have this one on my back up and I like it. I paid $50 back when it was on sale but not $99. https://www.primaryarms.com/brand-x-ar15-handguard-m-lok-free-float-12
  12. I have two of the Taccom 13/16 barrel and I am trying to find out how to ream it as well. Since I plan to shoot a match in a couple of weeks, shipping it out to a gunsmith is not an option. Would you mind sharing your experience with reaming the barrel? Also, could tell me where I can get the reamer? Thanks
  13. I had the same issue with my 13/16 Taccom barrel and FM9 lower. I simply filed the feed ramp to shorten it and mags seat fine (I still have to smack it in or open the bolt to seat 40-50 rounds loaded mags). HOWEVER, it still scratches the front of the magazine lip a bit. Most of my mags now has a dent in the plastic or even naked metal due to plastic falling off when it hits the feed ramp.
  14. No worries. Thank you for the replies. They were still educational to me.
  15. I made another batch with slightly less belling (0.382 ish) and made sure all the bullets are seated straight. I tested 100 rounds today and zero flyers. Thank you so much for your input. This Alpha dropper is pretty awesome. It does a good job with minimizing or even eliminating stickiness. I'd recommend this product, especially to people who automated their press.
