Yeah, thanks Homie. Max always leaves me feeling woefully inadequate. LOL!

Got a couple spinners at my next match. Any reason not to use a mag of my 9 major ammo on the pesky rascals with my MPX??

I can't begin to list the guns that were bought for me that became my wife's and I couldn't be happier. ?

Mine has lasted forever. Then again it has been in my closet of unloved gun parts after the first time I shot it. LOL Seriously though, I don't know anyone that runs a stock trigger in competition.

Correct answer. I like it so much though that I just carry a spare. When my first one died at about 13K rounds I sent it in and Hiperfire made it right. Now it is my spare.

One thing to add here is don't be afraid to bump the PF up. There is almost no difference in recoil impulse to me between 130 and 140 unlike with my blowback gun.

I am with you on the JHPs. I experimented for a match or two with molys and the difference was really noticeable. N37 might be a good choice. I was thinking of trying N38 just because I like it so much in my Open guns and have it whispering to me from the closet.

Yeah, the answer kinda depends on what you shoot. Moly projectiles and/or dirty powder will increase the frequency. That said I run PD 124 jacketed rounds and a clean powder and I take mine apart every 800 rounds, clean the snot out of it and change tappets. I have four tappets and rotate them. When one comes out it soaks for quite a while in cleaner, gets a good scrubbing/scraping and then goes back in line.

I have run a 2moa Holosun 510c at high noon in the middle of the desert and have never had an issue with brightness.

Nah.... pull the rear pin, hold the receiver/handguard well and give the top of the stock a good whack....... Or pull both pins. LOL

Agree. Returning to the OP's question, I have a friend with an Sig who has an aftermarket 16" barrel that has been magnaported. It is a very soft shooting, very, very flat shooting MPX. it is a different platform and I can't attest to how much, if any of that is due to the magnaporting but it is a great shooting gun. YMMV

Correct.

It doesn't apply because the PCC addendum supersedes it.

Washer off of one of the bolts that secures the barrel??

I like full FWIW, but it really is a matter of personal preference.

The easiest way to drop weight is to take off the thermal dissapator and replace the handguard. This will take a lot of weight off the nose which is where she will feel the reduction the most. if you aren't in love with the SCS replace that with either a Blitzkrieg or Taccom unit.

A really nicely engineered/manufactured mount. Quality like that never comes cheap. Heck, half the time stuff that sucks doesn't come cheap. LOL

I am with L9. I found the .223 produced less recoil and more importantly less dot bounce. Don't ask me why, I'm just here for the ride. :-)

Yeah, that is how most of us lefty's do it with non-ambi lowers on ARs. Faster than one would think and almost certainly fast enough for everything but a GM level reloading classifier.

Yup, that is exactly what I do. :-) It is right up there with C-more modules and CZ slide stops. LOL

My Hiperfire worked great.... for about 8,000 rounds. Yesterday at the range it developed the issues one normally sees when triggers get beat up in PCCs. I immediately removed the malfunctioning trigger and have replaced it with a new 24C.

Fair enough. I've had them send me warranty parts based just on photos before including a bolt carrier. None were such massive failures however so I can see them wanting to take a look at the gun.

The not selling parts was an issue of availability. For a while Sig was selling every MPX they could build so were putting all parts into guns or warranty replacement. That situation has improved quite a bit lately but I am not sure I would rely on that option completely.

I think you misread my post. You are correct that they won't sell you a bolt just because you want an extra, but they will send you one under warranty.

Get some Grump!
