  1. I ended up with 1 spare part, one of the keeper springs. I had installed a maritime bolt catch, but due the nature of the hammer pin directions, the maritime bolt catch covers the left side of the hammer pin, the maritime bolt catch was in the way, and had to be removed.

  2. Help please! Trying to replace the mil spec trigger in the DD MK18 with a geissele. The lower trigger assembly does not just “slide right out” as seen on various YT vids. Seems to be blocked by the safety. Any advice?

  3. I like how people say two-stage triggers aren't for shooting fast and that they're for taking more precise shots. I think that they never shot a good 2 stage trigger because shooting off of the first stage of the reset is laughably fast if you put the training in. I think most people who hate two stage triggers are under the impression that you have to fully release the trigger after each shot and that you HAVE TO go through both stages for each shot, otherwise they just don't know wtf they're talking about. 🤷🏻‍♂️

  4. I use and prefer his wife's trigger better. ALG QMS….like a super single stage Mil-Spec and for under $50. I have one SSA that I bought on sale over a year ago for $170 and that was bad enough. I can't imagine paying $240 for one. That's more than I pay for the Daniel Defense cold hammer forged chrome lined parkerized 16" stripped M4 barrels I use. I have a guy who buys in quantity and sells them to me for a great price. That's a bit steep as far as I am concerned for a trigger.

  5. So I'm building an Aero/BCM pistol and will be getting BCMs bcg, but Primary Arms will give you a discount on the G2S. I have their SSA in a rifle and love it, but seems like this is a great option for home defense, maybe?

  6. My ar only sends one bullet and then i have to reset the whole thing. My friend’s ar send as many bullet as he wants w.o. Him having to reset the entire gun. How can i get my AR to cycle like his?
