Gentlemen - I just received my approved ATF Form 1 allowing me to convert a Sig M400 Tread Pistol https://www.sigsauer.com/sigm400-tread-pistol.html to a SBR. When getting my 50-yard zero, I found the trigger to be very heavy. I didn't put it on my trigger gauge but I'm guessing it's about 15 lbs.
I've replaced a couple AR triggers with the CMC units https://www.brownells.com/rifle-part...prod31715.aspx. These have worked well for me. Are there other proven alternatives I should consider? Thanks very much.
