Hi all,

I purchased a new to me m&p10 today. I’ve done quite a bit of research on the proprietary bits, and I understand the trigger can be replaced with any Ar15 trigger.

After bringing home the rifle I decided to replace the stock trigger with a larue mbt2s curved bow trigger I had in another rifle for some time. Well when the safety is installed and on the fire position, the trigger will not release. I have tired the stock s&w safety, a battle arms development safety, and a mil spec safety with the same results. It does not matter if the grip is installed or not, the trigger will not release the hammer.

I then tired another larue mbt2s flat bow trigger. This trigger would not even function, even without a safety installed in the lower! The curved bow at least would function without the safety installed

Has anyone ran into any issues running aftermarket triggers in their m&p10s, particularly the larue mbt series? I’ve had both of these triggers for a year or two now and they’ve been nothing but great in other lowers.
