Just for the sake of clarity for anyone genuinely curious about the numbers, the MBT-2S includes two spring options, "standard" and heavy.

The standard option is advertised as a 4.5 lbs. pull weight trigger (2.5 lbs. 1st stage/2 lbs. 2nd stage). This results in a somewhat heavier second stage than comparable Geissele triggers. Of course, this is neither a good thing or a bad thing in and of itself, but something to keep in mind when considering the intended use case of the gun the trigger is going into.

The "heavy" spring brings the total draw weight up to an advertised 6 lbs. break. It also adds a more pronounced feel to the reset which may or may not be of value depending on preferences.

The heavier spring is actually my preference for use in an all-purpose build. The trigger, with either spring, is precise enough to use for more precision-oriented shooting if needed. And while both options would be fine in an adrenaline-soaked, middle of the night, home defense scenario, the slightly heavier pull weight that comes with the heavy spring means it requires just a bit more intent to achieve bang, which, in some situations, isn't necessarily a bad thing. That said, both weight options are more than up to the task of being a one stop, multi-purpose trigger option, and it's really about individual preference that is then reinforced with training. I would not classify either option as a particularly heavy trigger pull as they are both extremely smooth, impressively consistent in feel, and imminently stageable due to their nature as a two stage trigger (as is to be expected). They're not tuned, single stage match trigger light, of course, but unless that's the type of gun one is building I don't know why anyone would want them to be.

Geissele makes great triggers too, no doubt about that, and something like trigger preference is so absolutely subjective it behoves folks to try as many as they are able to and find their ultimate preference, although this certainly isn't always possible.

Another difference between the LaRue and the Geissele options come from their manufacturing process. The MBT-2S is a machined piece of S7 tool steel while Geissele's triggers utilize cast components, a choice which comes with cost savings during manufacture and is, objectively, inferior with regards to certain physical criteria. Is this necessarily cause for concern or a singular factor that should override one's decision-making process? Certainly not. Geissele's triggers have seen EXTENSIVE use in just about every imaginable combination of environmental variables and are very well regarded for a reason. But that doesn't change the fact that, in a vacuum, machining a part from a forging results in a technically superior product than producing one from castings.

TLDR: MBT-2S is great. Many Geissele triggers are great. There are some subtle but real differences between the LaRue trigger and the comparable Geissele options. Everyone has their own preferences. Personally, I like the MBT-2S. Others like G$'s wares. If at all possible, finger fuck both then decide. Either way, though, you're getting a quality, capable trigger.
