The ELF AR-9 Drop-In Match Trigger has been built for performance. Specifically developed for 9mm and .45 PCC platforms, after tens of thousands of rounds of testing in all platforms, the boss has decided this is the best trigger we have ever produced and does it all in every AR platform. It has a u-shaped captured disconnector that forces a positive hold on the hammer and also has a “pad” that matches up to an extension on the hammer. The pad is directly in line with the rear trigger pin so when the hammer is stopped by those matching surfaces it effectively eliminates trigger slap from the hammer hitting the disconnector and greatly enhances the feel of the trigger during live fire.
