Working in s&w mp 15-22 - OpticsPlanet Exclusive RISE Armament RA-242 Enhanced Rifle Trigger

There was not a good answer about this trigger in the M&P 15-22 so I purchased it to try. The trigger fits and operates in teh 15-22. It feels good with a smooth short pull and positive reset. I gave it 4 stars because it has an odd feel if you manipulate the reset by hand. After some extensive searching I found one answer that this is per design and is intended to be for blow-back rifles. I think that should be somewhere in the trigger documentation. The anti-walk pins are too narrow for the M&P polymer, but I just used the Mil-spec pins that were in the rifle and they work fine.
