When you say "take up" are you talking about slack or creep?

There are a few terms for triggers and how they work. They are:
  • Slack
  • Creep
  • Break or Sear Break
  • Over-travel

Each is unique. So, here's a little primer so we're all on the same page.

Slack
This is the free movement of a trigger before it's against the sear. This is most often found on pistols. The typical AR with a GI trigger usually doesn't have any slack.

Creep
This is the movement of the sear before it lets the hammer go. When you press the hammer back it comes to a stop just before the sear releases the hammer. Any movement from this point until the hammer is released is creep. The typical GI trigger on an AR has a lot of creep.

Break
This is the moment when the sear releases the hammer. Most guns have a clean break. Some, like the Glock, have a kind of spongy feel to the break. ARs generally have a very clean break. This is sometimes difficult to discern on a GI trigger because they have so much creep.

Over-travel
This is the trigger continuing to move after the break. Too much over-travel will cause the shooter to pull the gun off line. The M&P pistol has a lot of over-travel and this is the main cause of accuracy errors in that gun. Over-travel in the M&P15 is not consistent and must be evaluated for every gun.


ARs with a GI trigger usually have no slack when cocked, tons of creep, a decent break and very little over-travel. Almost all of the aftermarket triggers improve on all these points.
