I have a lightly used Elftman Tactical Match Trigger for an AR15 or AR10. This trigger is amazing, but I needed to switch to a 2 stage trigger, so this trigger unit needs to find a new home. It has next to zero take up or creep or over travel, and really nice crisp break, and the shortest reset of any trigger I have tried. It is also extremely durable and safe. Worth every penny of the $250 msrp.
Here is a review of the trigger from The Truth About Guns:
I am letting it go to a new home for nearly half of what I paid for it. My loss is your gain. It still has the lifetime warranty.
