I’ve been using a Bill Springfield’s worked 3lb trigger, very nice by the way, until I received the Alexander Arms trigger I ordered back in Aug. Package was very well protected and the items inside were sealed in individual sections, didn’t have to worry about thing missing in the packing. When I opened the package to inspect it, found they sent the wrong allen hex key used to fine tune the adjustment on it. Size is 0.035 and could not find one around town, so Sears.com to the rescue. Ordered a full set of small size hex keys along with a few extra straight ones (good thing as they sent the wrong size straight ones). Also sent an email to Alexander Arms on Dec 2 explaining that I needed the correct size allen key, still haven’t heard back from them as of yet. Got the trigger installed today with some rounds down range. It came with a detailed instruction sheet, but I still had to check their web page for a picture of the trigger spring setup. After that, no problems. While dry firing (making sure the hammer did not hit the receiver) to check the safety and reset, the trigger did not always reset by itself. Live firing on the range it did not reset by itself twice during shooting about 75 rounds. All it took to reset it was a slight push forward on the trigger. I may not have it adjusted just right yet. When it did work right, WOW! Very little takeup or slack, not too light before breaking and not much movement after firing with a quick reset. I’m thinking it was worth the wait. I will update some more after I work with it some this week.

Hey Dan - what are those tubes between the receiver and the barrel with the blue dots on them?
Those are witness marks on his DD Lite rail so he knows if the screws loosen up.
Looks good–ya’ll missed the spring in that pic----
RE4, those are part of the Daniel Defense Lite Rail. It is a free float rail system using a steel barrel nut, which allows the upper receiver to have a continuous uninterrupted upper rail platform.
