Know what your getting into - Elftmann Tactical Elf Pro SE Trigger

So here is the deal. This trigger is the best available for a mag fed shotgun so if your setting up a VR for open 3 gun you will need it. That said there are issues some are ELF design issues, some are armscor manufacturing issues, but combined if you dont know a fair bit about how ar triggers work and are scared to modify parts and or your gun you should probably move along. First the screws will come out and get lost the only solution is very strong loktite which essentially permanently installs the hammer. Next the pin locations vary enough they have to leave plenty of metal on disconnector and hook. If you don't know how to time the disconnector if yours won't reset stop here. Finally the hammer springs usually won't clearance vs the front corner of the reciever, so when you have to smash it in there your going to get coil binding and light strikes. ELF thinks thus has something to do with spring weight, it does not, you will probably have to remove metal from front of trigger pocket to make room this will solve the problem but it may not be for you.
