This will work with any standard mil-spec lower receiver, so this will work with your M&P-15 22.
AWP and ARP are not the same. AWP prevent the pins from walking out of the lower receiver, ARP does that too and adds 2 arms on either side of the receiver and makes a physical connection between the 2 trigger pins and prevents the pins from rolling in place and causing things like unpredictable double fires....... that said ARP are a mil-spec style trigger thing and add no value in a box trigger like the one above.
yes, this trigger will fit virtually all AR-15 lower receivers.
As long as they utilize an AR trigger and the receiver has a milspec trigger pocket.
Yes it will work. Highly recommend using a premium ammo like CCI. Anything cheap could result in failures to feed/cycle
yes, this is compatible with the DPMS AR's
The model is the same, just different anodized finish on the housing and laser markings
All RISE triggers come with small pin diameter bushings. You can reach out to help@risearmament.com for the large pin bushings
The RISE Armament Special-Edition DTOM Trigger Assembly will work with an M&P15 Sport 2.
The RISE Armament Special-Edition DTOM Trigger Assembly might work in a Sig MPX however, I recommend using the PCC specific Rise Armament Trigger or the Timney MPX Trigger at the link below.
