Anti rotation pins commonly used on cassette/drop in trigger units. Most of the units don't have the springs in the hammer or the spring foot from the hammer spring to keep the pins from sliding out.

 

They are part of an aftermarket trigger and hammer pin kit.
The plates prevents the pins from walking out of the holes when firing the gun or under recoil.

 

If you decide you want them, make sure to order .154 diameter. Depending on your trigger, they may be unnecessary, but I put them on both of mine.

Just my 2c worth...

 

Good question OP as I wondered about that as well. LostHawaiian, what size would I get for the Gen 2 Timney trigger, .154? What brand would you recommend?

 

I prefer the more subtle anti-walk pins if I wanted a set.

That's a great option with a attractive price.

 

Anyone here have experience with the Hipper trigger? (competition one)

I have used the Hiperfire Competition in the past for many matches. It’s good but the Eclipse is better and smoother (more expensive too) since it’s coated in Nickel-Boron. I have Hiperfire eclipse on both my MPX.

I used the heavier dual spring to get the lightest trigger pull of <2#. It’s a single stage and reset is very short. I have over 10k rounds with the Eclipse without any problems. I clean my lower by spraying non-chlorinated brake parts cleaner and blow it using my air compressor.

If you’re not competing, the stock Timney is more than enough. I used the stock Timney on my PCC model in a match and I was missing the Hiperfire eclipse on my main MPX (8” sbr).

 

@losthawaiian. What kind of bag is That in the pic..can u put both of your mpxs in it

 

It's a Savior T.G.B. 34" Discreet bag, and it's great. The quality is excellent and I really like the design.

You can use it for 2 rifles, but I have mine set up for just my PCC Competition model.

On the other side of the divider, it's all velcro and webbing so you can configure as you like. If you wanted another rifle there, you'd just put on straps. I have mine set up with Mag pouches and store my belt pouches there.

The whole front of the case is another section that you could store mags and stuff in if you have 2 rifles.

In this pic, the flap covered by the stretch cord can unzip and flip up and runs the while length of the case. It's fully lined with velcro. The short zipper at the top is another slip pocket that's fairly large. I keep a couple of velcro pouches in the main section with cleaning supplies, tools, and things I might need at the range, and in the smaller pocket I have some micro-fiber towels and my glasses.

The back has an ambi sling strap, which is great for toting around.

For my "K" I have 2 bags, one for the range and one that I carry around as my EDC.

Range: WRB 18" Pistol Case.

...and for EDC a SIG Sauer Laptop Bag

These are a little harder to find. I picked mine up new on eBay a while back. I can fit my laptop or iPad in there with my MPX K.

Hope this helps...

 

Thanks Hawaiian that totally helps out!

 

Cptroost,
Here’s my reply to your because you can’t receive any until you have 25 posts.

I haven’t tried the Calvin Elite due to some competition shooters having problem with them on the MPX.

I also haven’t tried the Franklin Binary because it’s not legal for use in USPSA. I strictly use my MPX for competition and nothing else.

 

Thank you for your reply!

 

Guys,

For the KNS Gen 2 mod 2 pins, I only see Gen 2 MOD 2 in this thread. Anyone know if the thicker gen 2 pins will work as well? I like the emotional idea of the thicker pin being that these guns are hard on hammers. I'm sure the Gen 2 Mod 2 is just fine but i like the look of the standard gen 2.
