This single stage trigger is user-adjustable from 2.75 to 4 pounds pull weight. It is absolutely drop-safe regardless of pull weight.

The ELF Drop-In AR-10 Trigger has been built to withstand the punishment of high powered calibers. The only AR-10 trigger using aerospace grade sealed bearings, making for an incredibly smooth and fast trigger pull. Our exclusive .043 double wound polished piano wire hammer spring ensures full ignition of any ammo including .308 and 7.62x39. Pull weight from 2 3/4lbs to 4lbs is so easy to adjust it can be done in seconds without removing the trigger from your lower receiver.

Needs refinement, redesign.

I really wanted this trigger to be a drop in, no problem solution to the standard trigger. First problem was that the screws on the bottom are non standard, couldn't find an Allen wrench that fit. Ended up using needle nose pliers. Next problem once trigger is installed , set screws are to be placed on top. Allen wrench fits these, yeah! Except spring legs block the holes where they are to be installed. Get a punch, work an hour trying to pry spring legs out of the way and finally get the 2 screws installed. Finally, nice crisp trigger with no problems. Wrong. Trigger is crisp and breaks nicely, BUT, disconnector sticks and has to be unstuck by pushing on trigger. GEEZ! for $250 there could be a LOT more thought put into the design. I'm not taking the damn thing out though because after an afternoon of screwing with the thing it's going to have to work as is. Disappointed.

Best trigger i own, read the instructions!


I read the previous review, and all is solved by reading the instructions. Cant comment on the spring legs (I have no idea why those are included or used, they’re not in mine and not in the instructions), it works fantastic. But, here’s the issue I ran into: I didn’t follow the instructions the first time (who does right?). I found out if you don’t set the set screws right or you go past the lightest setting, the trigger won’t reset properly. So it’s simple, just go back until it resets again and you’re at your lightest setting, and boy is it a smooth crisp, lightweight break.

Easy and awesome


this trigger is absolutely fantastic, EASY to install just read EASY to adjust pull and breaks like glass best drop in I have had so far
