  1. GG Hybrid competition kit (with the NP3 sear) competition sear springs + the heaver trigger return spring +armory craft trigger. have about 0.012" pre-travel, zero over-travel , positive reset.....
  2. Reality is Primer production is limited even in normal times... Vista outdoor controls 70% +/- of the primer capacity in the US (federal & CCI) Winchester has been on a downward spiral in quality and capacity for several years and now has to manage Lake City as the new contract administrator stretching their administrative capacity.. Remington is bankrupt, ammo side has an offer to buy out for $65mil + assumption of debt, that leaves huge questions on the supply chain of raw materials for any new owners of Remington ammo.
  3. Never liked the 512 interrogated mount, the height over rail is to low (Absolute co witness height) so it requires a riser, glass is so so. Reticle is not bright enough for full AZ sun. Skip any Sig optic that is not a T version, IPX 8 vs IPX 7 environmental sealing are well worth the small cost increase. Replaced 4 UH-1 with Sig R8T’s, bigger window, clear glass , super crisp reticle, windage and elevation are adjustment are internal on the reticle. Windage and elevation are adjustment are in the mount in the UH-1, I had 3 where the windage tension loosened up after 25K and
  4. way I have done it for 30 years in USPSA is I keep mine loaded all the time until I make a decision to switch divisions for at least a mouth or 2.. down load and clean anything as needed on a stage then reload it and back in to rotation.. 2011's get new springs once a season, PCC's get new springs as needed when the springs get a curve in them..
  5. Yea same for me in 30 years at this sport I probably have less than 5 hours total of dry fire, no routine practice might do 100 rounds of drills if I am on a range to adjust a Zero or do some chrono work 2-3 times a year... I just shoot 6-8 matches every month
  6. STI is gone: http://www.digitaljournal.com/pr/4693452
  7. PN: 1810939-R / OP ROD 1810942-R / BOLT CARRIER, 37 HP, FG 2402083-R / BUMPER, RECOIL KIT-MPXUPPER / UPPER RECEIVER ASSY, MPX, SEMI, DUST COVER, EJECTOR, BARREL CLAMP, HARDWARE I called a few times and was told $50 shipping on me for evaluation (whole gun) , any aftermarket parts were automatic disqualifying on a warranty request and I was well over the 25K service life of the system... I finally got someone willing to work with me and have kept him as my POC, however I am a retired military armorer and held SIG certifications for
  8. common issue with the Carrier and spring guide .. the cross dovetail on the spring guide is what is gouging: 1. check your ejector to ensure it is tight in the upper receiver as this will contribute to the issue 2. shift to a faster burn rate powder OR shift to a restricted gas plug (0.052")...MPX's are burn rate sensitive I normally run speer 115gr TMJ that is 1400fps with .0520 restricted gas and 13% reduced recoil springs when I go to 115gr JHP @1400fps with 5.9gr of CFE Pistol or 5.2gr of Sport Pistol I have to change to the .114 gas plug( factory Open).. when I use fed 115gr JH
  9. What # of USPSA matches are you shooting per month? their is no substitute for shooting matches, will any of the clubs let you pay an additional fee and shoot the whole match 2 times as just another shooter on your squad? Are you evaluating your performance to the other divisions in HOA for the match and individual stages?
  10. I have been shooting this sport since 1990 and never heard of the veloicty limits your talking about... early on major PF was 175 so everyone targeted 180PF for comfort..had guys running 88gr JHP @2045 fps 115gr@ 1565 fps... FYI current USPSA velocity limit for PCC is 1600 fps... the 9BPLE and XM9001 are federal factory loads out of a 13.7" barrel garentee the would be faster from a 16"
  11. Yea ended up their after 3 years of development started with 124's with the stock flash hider Moved to 115gr after adding the MBX comp the 9BPLE Load: groups under 2" at 100 yds (100/26 yrd BZO ) matches up to the 500yard 5.56mm BDC point in the EoTec / trijicon /sig reticals @ 175 yrds for the long range targets at the AZ State PCC match only rises a max of 1.9" (@ 65 yrds) falls out of that 1.9" @115 yrds ( gives me a center hold on a 8' plate anywhare from 5-115 yards) Matches the CQB 7yd point of reference in the same recitals gives me sa
  12. MPX’s need to be tuned just like a blow back PCC however the process is different: 115gr @ 1425FPS: Speer TMJ , Federal 9BPLE, Federal XM9001 and a N340 reload I use a 0.0520 gas plug in 2 of my guns and a 0.0469 in the third with 13% reduced recoil springs in all 3 guns 115 JHP reload with 5.9gr of CFE Pistol I use a 0.114 (open) gas plug in 2 of my guns and a 0.0520 in the third with 13% reduced recoil springs in all 3 guns Same bullet weight, same velocity, same power factor = 47% change to the gas flow based on the power burn rate
  13. USPSA Added P226 LDC on 12/2/19... and I see them around now
  14. I have been using slide mounted RDS since 1995-6 ish ... just adding threaded holes with out any other stability is a recipe for RMR/SRO optic failure.. the slide cut contacts the DPP / R1Pro stabilizes the optic front to rear, and reduces the load on the screws that is why i didn't install the shroud on my R1P as it raised the optic up and reduced contact front and rear with the slide cut out..
