Hi ..
after a couple of months i decided to finally invest in a Geisselle trigger. Reading a lot of reviews, i think that the SD-3G will be my choice but im a little confused regarding the 2 options that i can find on Midwayusa:

a.- Geissele Super 3-Gun Trigger AR-15 LR-308 Small Pin .154 Matte

b.- Geissele Super Dynamic Trigger 3-Gun Version AR-15 LR-308 Small Pin

Can anyone tell me which one should i select?
Do i have to order extra pins? I understand that it should be an easy "plug&play"?
Are there installation videos around? Specially for our MP15-22.
Thanks again guys..

Either one will work I believe, best thing to do is visit the Geissele web site for the difference. Just for reference any trigger for the AR15 should work in the 15-22. Same with installation, any video for the AR15 will explain the installation in the 15-22, they use the same FCG.
 
The Super is a curved trigger while the Super Dynamic is a flat trigger. The SD can feel like it has a lighter pull if you use the very bottom end of the trigger. Somewhat of a personal preference thing. The SD costs more also.
Personally I would not use any other brand and model of trigger, especially for action shooting.
 
Thanks photoracer and cjt50. Do i need extra pins?

15-22 uses standard AR platform pins

It does if you use standard pins. But if you want captive pins like the JPs or locked non-rotating pins like the QNS set they have to be longer because the S&W lower is thicker in the outside dimension. I think only QNS makes a longer set to use in the 15-22. Keeping the pins from rotating greatly reduces the wear on the holes in a lower receiver (I know that ARs do wear because that is the reason for over-sized .1555 pin sets). That is why I use them.

I assume these are the non-rotating pins you're referring to: https://www.primaryarms.com/KNS-NonRotate-Trigger-Hammer-Pins-for-S-and-p/mp15-22nrthpbk2.htm

Kinda pricey for pins, but I guess if regular pins are going to rotate a lot and eventually render the receiver unusable, it would be worth it.

Edit: Seems Geissele recommends against using KNS pins in their triggers. I suppose I'll go with Geissele's advice and hope the Geissele pins don't rotate enough to ruin the 15-22 lower, and if it does, hope that by the time that happens, S&W will sell 15-22 stripped lowers.

I have over 12k through my 15-22 and the pins are as tight as the day I bought it. Then again, I don't take the pins out every time I clean the rifle. IMHO, the overwhelming majority of the problem with rotating pins is caused by people disassembling the FCG every time they clean.

Good point. I've always felt that too many gun owners clean their guns too frequently. This might just be another reason to limit the amount of tearing down one does to clean their gun.

There's little, if any, reason to disassemble the FCG. 90 percent of the time, blowing it out with about 90 psi of compressed air will get rid of all the powder debris. Spraying a little CPL on the FCG before the compressed air will take care of the other 10 percent as well as giving it all the lube necessary.
 
I have used the KNS pins on both my 15-22 and my 3-gun AR with no issues at all. The only time I take them off is when I am changing something in the trigger like springs. I use a needle oiler to get some lube on the pins and use their grease (Mobil 28) on the lube points.
