I looked around the web and this site and have found a few opinions but nobody has said i tried it and it worked or did not. I want to get a new trigger for my DPMS LR-260 and was wondering if i can use and ar-15 trigger. Thanks for any help.
AR triggers are typically interchangeable. As long as you're not swapping the trigger in a Colt AR-15, you'll be just fine. The Colt has a large pin whereas pretty much everything else is a small pin.
As has been stated, stick with Geissele. They're second to none.
