Questions & Answers
Do I need any specific trigger pin for this trigger to be used in a MP 15/22? Expert Answer

Geissele states the Geissele Super Dynamic 3-Gun Trigger is only compatible with Mil-Spec AR15's and not compatible with pistol caliber variants. They do not state whether the Geissele Super Dynamic 3-Gun Trigger will work with an M&P15-22 and if using the trigger with that rifle will void the warranty. I recommend contacting Geissele to confirm compatibility of the Geissele Super Dynamic 3-Gun Trigger and that rifle.

looking for a fast trigger for a b&t ghm9k, 1 will this trigger work. 2 what anit-walk pins would I need to pin the trigger. Expert Answer

I would recommend reaching out to B&T directly as they state that only some AR15 style triggers will be compatible with the GHM9 but do not specify which. They also state a trigger upgrade will often require modification. B&T should be able to provide you with more information regarding upgrading your trigger.

Sd3g! Best trigger on the market by Tpow91, Verified Owner, November 12, 2017
This is my 3rd SD3G Geissele trigger and I can't say enough about them. I've had Hiperfire 24C's , Timneys, and CMC's but this is honestly the fastest , smoothest shooting trigger I've ever used. Geissele makes the best hands down, the packaging is p...

Awesome Single Stage Trigger by Monz, Verified Owner, October 29, 2025
I put this marvel in my Daniel Defense DDM4V7 and I was off to the races. I had read some mixed reviews but I'm glad I purchased this. I was a little worried that this was going to be too much of a feather light trigger. And despite being installed w...

Great trigger by Bob, Verified Owner, August 7, 2025
Im not saying the Geissele is the best trigger because I haven't tried every other options. I do have more than one Geiselle however as well as others, and all do their job well enough. I installed the 3 gun trigger with the lighter spring and measur...

fantastic trigger by VaOutlaw, Verified Owner, May 21, 2024
The Geissele SD3G is a fantastic trigger for trigger snobs like myself. I put the "black" spring in and I am getting constant 3 lb trigger pulls. The takeup is very short to non-existent. The break is crisp. The reset is very short and positive. The...
