Questions & Answers
Will this fit a DPMS style AR-10? Expert Answer

The CMC Triggers AR Lower Assembly Trigger Kit might work with a DPMS AR10. However, do to dimensional differences between AR15's and AR10's as well as many AR10 models having different specifications fitment cannot be guaranteed.

by Hunter, Gear Expert, June 14, 2022
Will this work for a AR-9? Expert Answer

The trigger will fit a firearm that uses mil-spec trigger groups and has the cavity milled out to accept a drop-in style housing. There are specific PCC triggers because of the abuse that blowblack firearms impart on to the trigger group, so we normally recommend going with a trigger meant for pistol caliber carbines like this: https://www.opticsplanet.com/cmc-triggers-ar-single-stage-9mm-trigger-pull.html

Great trigger kit! by VonWhip, Verified Owner, April 26, 2021
