Hello: The Sig likes faster lighter bullets. I really like the 115's in my MPX at 138-141PF. It makes it cycle quickly so you can get back on target faster. I have not had to open up the gas port on 3 MPX's I have had and still have. It likes to be well oiled and around 500-1000 rounds it works great. Thanks, Eric

Hello: Some lowers are lighter than others as well. I like the QC10 because of the cutdown magwell area and they just run. I have Glock and Colt magazines lowers and they both work well. The lowers with very high round count around here are JP, Sig MPX and QC10 with some having over 50,000 rounds. I have over 10,000 rounds through one QC10 and only 3,000 on the other. I think some of the magic is in the lower but even more in the upper setup. Thanks, Eric

Hello: Oil is your friend. Thanks, Eric

Hello: No broken firing pin? Thanks, Eric

Hello: Make sure the bolt is well oiled. Running it dry causes all sorts of problems. Thanks, Eric

Hello: I have tried 7 different triggers so far and the ones that hold up and work in every PCC AR9mm I have tried them in are the Mil Spec trigger with JP springs and polish job, Hiperfire 24C and 24 3-gun and Eclipse, and also the JP trigger. The problem I have seen is that some of the milspec upper receivers have the bore higher up than some of the others. This causing the trigger not to reset or get hammer follow some times. Thanks, Eric

Hello: Is it not cocking or are you getting hammer follow? Thanks, Eric

Hello: Remember to take to twice as much ammo as the match will need. That way if you have a reshoot or three you will have enough ammo. Thanks, Eric

Hello: How many rounds are each stage? I typically carry two on the belt and one in the gun. That is over a 120 rounds if I use all big sticks which should be plenty. Thanks, Eric

Hello: If you like most of the parts on the JP then I would say it is a good choice. If you like building then I would build one the way you want. Alot of the problems I am seeing are with the angle of the magazines in the lower if using Glock magazines. I am having great success using the Quarter Circle 10 lowers. They just seem to have the angle correct and make building a PCC easier. I am not sponsored by QC10 or JP but do like their products. Thanks, Eric

Hello: Also train the RO's to look at the timer to see how far away they can get and still pickup the shots. Also have them look at the timer to make sure they get the last shot. Thanks, Eric

Hello: What type or bullets are you using? Did you check to see if the gas pistons rings are staggered so it seals? I use Tite Group and plated bullets mostly and have run 1000 rounds before I clean it. I do run a bore snake through it after a day of shooting. I also oil the bolt as well. I do put one small drop of ATF on the piston rings after I clean them. Makes cleanup easier I think. Thanks, Eric

Hello: I have been using the TTI plus 11 base pads and they work great. I have two that actually will hold 42 rounds and one in the PCC. I mostly load them to 36-38 rounds to keep them lighter and not over stress the spring. The biggest round count stage I have run here is only 38 rounds with some steel. Thanks, Eric

Hello: Going to try the Taccom coupler first on the Sig mags. The Taccom coupler works well on the Glock and Colt mags I have. I will use a 30 and a 20 first to see how they work. After that I will try the 30 and 30. I have been shooting the AR9 mostly right now so the Springer extensions may be a while on my Sig. Thanks, Eric

Hello: No riser for me on 3 different AR setups including a S&W 15/22. Thanks, Eric

Hello: they seem to be an OK setup but they are heavy. Thanks, Eric

Hello: Because I have shot both and the longer barrel works better unless you are in really tight areas. A couple of others have done the same here also finding the same result. The key is lighter weight for the 16" setup. Thanks, Eric

Hello: I would build a new upper for the AR9mm. 16" barrel and light. I suggest a Hiperfire trigger or a JP. They seem to be the only ones that will last around here. The recoil on the CZ are harsher than the AR because of the heavy bolt. Both will get the job done. Thanks, Eric

Hello: Springer Precision make a segmented extension pieces. Taccom make a coupler so you can join two mags together. I am using the TTI extension and they have been great. I may have to get one of these plus 20's to try. Thanks, Eric

Hello: Wow that is a fast load for the MPX. Is it a dirty load? I am using 3.8 grains of Tite Group with 124's. Thanks, Eric

Hello: You maybe able to build one cheaper than they sell theirs for? Start with a 8" pistol and go from there. Sell off the 8" barrel and get a 16" ILWT one and add all the parts you like. Thanks, Eric

Hello: If you are shooting at 100 yards use 124 grain bullets and a 1-3 or better scope. Know where your bullets hit at different distances and use 140-145PF loads. That has worked for me in the past at The Texas Carbine match even with a Mech Tech. For good groups use good bullets. Thanks, Eric

Hello: I think it depends on the weight of your handguard. As I have stated before I think you can make the too light. My lightweight upper weights 2lbs 1oz with no bolt or charging handle. I think it is about as light as I would want to go. My other lightweight upper weights a little more and I shoot it just as quick. I would turn it down to 0.700" diameter and try it. 5/8" diameter is kinda a standard measurement but I have also seen 0.560". If your barrel has a sight boss turn that down first and check it. It is easy to remove weight but harder to add weight to a turned down barrel. Thanks, Eric

Hello: I am using and have used Anderson sport, QC10, Matrix, JP, upper receivers. All have worked perfectly. The Anderson sport upper is the lightest I have used so far. The barrels I am using and have used are KAW Valley, Faxon, JP, and Wilson Arms. Hanguards I am using JP, Nordic 22 one, Taccom carbon and a KAW Valley carbon fiber one. Thanks, Eric

Hello: I am not so sure on "Welfare Open" since some guys have alot of money in their Carry Optic setup. It's all fun and if it brings more people back to the sport and into the sport what does it matter. Thanks, Eric
