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.

Helpful Positive Review Excellent Light and Quick. by Sixmilejohn, Verified Owner, November 2, 2024
If you're looking for an excellent light pull (4lb.)trigger with short reset and excellent break, this is it. Recommended for 3 Gun or Range Shooting. I would not use this in a Home Defense rifle or pistol carbine.

Helpful Positive Review 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...
