  1. did you use the PSA hammer or the JP hammer?
  2. Should a JP trigger work w. PSA 9mm Hammer in a PSA 9mm gun? I believe that folks are saying that JP triggers will run in most PCC's but I'm not sure if they are talking about JP hammer and trigger or just trigger. I have a CMC PCC trigger and it feels nothing like the ones I have in my other 223 rifles. Thanks
  3. I looked through several threads already so apologies in advance. I have a PSA AR9 lower, complete TACOM upper w. TACOM recoil guts and 14.5 barrel. CMC PCC trigger was working, then sputtered a little. I lubed it up and it kept running without another issue. Gun it/was very new w. 300 rds thru it. I have experimented w. JP trigger and stock hammer and disconnect or that came w. PCC. This combination of JP trigger, the two screw adj. one, and PSA stock hammer appear to work but have not shot it yet. Does can anyone please confirm that this combination SHOULD or SHOULD not work. Trigger pull is heavy as it still have stock hammer spring but I like the reset better than the CMC trigger. Ill order a JP RP spring provided this SHOULD work. thanks
  4. Dude, I think you have all kinds of gun/ magazine / ammunition issues. The MOST likely cause of a malfunction in an AR, and I have to assume its an AR as you don't say, are magazines and lube. Since you changed several items; I think the MOST likely cause is the ammunition, possibly the stock some how, and finally the magazine. The magazine is last provided you have had those magazines run in that gun before. Magazine extensions COULD cause failure to feed issues if there is something going on w. the spring or its assembled incorrectly or its just plain full of crud. "No problems other than one double fire" is a BIG problem that needs looked into, you also need to make sure you did not simply bump fire the trigger which can happen. Look at the ammunition again, are they really light hits or just firing pin dimples? Excessive sizing can cause issues and create an excessive gap between bolt face and firing pin.
  5. I might take a different approach to this one. While I don't exactly know what a tac rifle match is where you shoot, I might consider what the CLOSEST targets that I might expect. If, for example, "Close" targets are 25-50M, then I might consider a 2-10X scope. There are several good 2-10's out there but I like the Vortex. I know its a response that you did not ask for but that's what I would consider if it was me.
  6. Don't create solutions for problems that don't exist. Your rifle is fine, I suspect, with ANY primer, pistol or rifle. If the hammer is staying back, I don't think you will get a slam fire. Go shoot and check back in if you do. in the unlikely event that your rifle is not 100% fine, your not going to hurt anything.
  7. ummm. If the firing pin is striking the primer then the gun will go bang... How are you not getting slam fires? are you getting dimples on the primers? that's different... and normal. Is the hammer following the bolt when you release the bolt and hold the trigger? what exactly is happening?
  8. No..... A bushing in a bushing die does not "float". A bushing die, FL or NK allows you to control the OD of a sized case. This allows you to do a few things like control neck tension and eliminate the use of an expander button if you turn your brass. increasing or decreasing neck tension can have a positive effect on accuracy. Eliminating the expander button can help to eliminate excessive wear on case necks and reduce work hardening as well as the chance of split necks. Generally speaking, you want .002-.003 tension for a gas gun and .001-.002 for a bolt gun and a bushing die, or a custom honed die allow you to set the neck tension for a specific case or a specific neck turned batch of cases. If you switch to thicker neck cases you would have more neck tension than a thinner necked case. As already pointed out, bushing dies will not size all the way to the shoulder and all new brass should be FL sized in a normal FL die before using a bushing die. Bushing dies will allow case modification; i.e. you can neck down 6.5 CM to 6mm by putting a 6mm bushing in a 6.5mm CM bushing die etc. All things being the same, any quality die will load quality ammo with minimal runout provided you have good brass. I have all kinds of .223 and .308 dies from shooting NRA HP for years, the bushing dies are a bonus as you can work the brass necks a little less but that's about it. For the money, I really like the Wilson dies with a carbide button. If you are mixed brass, there is not an advantage and they do cost more.
  9. I adjusted my gas block to run w. my 62g short range ammo. That ammo has same powder charge as longer range ammo, 24.2 TAC, and I can go all the way down to 50g bullets and the rifle still runs w. same powder charge. I don't know, but I think that the gas volumes is the same as I'm running the same powder charges but the heavy bullets are running higher pressure, and as such the system still runs.
  10. not to burst your bubble.... I have found that PRIVI bullets don't shoot well, there is a world of difference between FMJ bullets and PRIVI are at the low end of the list. 50 yds is way too close to check loads for accuracy other than to see if the bullets are stable or coming apart; you need 100 yds at a minimum and really need to shoot 10 rds to get a good idea as you want to verify in a hot barrel. I am looking for 1.5-2" for 10 rds at 200 yds with a not terrible ES and that's it for 3gun, highpower ammo is different. I went the route of verifying that my 77g load worked out well enough and then tried same powder w. 62g H FMJs. They shot well enough for use to 200 yds. and close enough to same POI.
  11. So I went half way, psa lower w cmc pcc trigger and an entire taccom parts upper and taccom recoil system I opted for 14.5” w pinned comp
  12. Thanks all Fort polk is still here We do have a uspsa style club and its not too bad; last match we had 50! I think ill pull the trigger on the psa ar9 and put a jp silent capture short stroke kit into it and see what happens
  13. Team, Any comments on building up a PCC from PSA AR9's? I was looking at upgrading to the JP short stroke silent capture kit, comp and CMC 9mm PCC trigger to a base rifle and going from there. Do these rifles run? Alternative is building a mostly JP upper, a mostly TACCOM upper.... or .... yes I know, just buying a complete JP rifle. Thanks
  14. Thanks all. I will also try the shorter ammo
  15. The TMKs end up getting seated deeper in the case so you might have to back down your load. Also, seating stem compatibility is more of an issue w. TMK than w. SMKs or other BTHPs
