POF Drop in Trigger AR15 Brand New

[mongoosesnipe]

How big (size/volume) that hammer appears is a clumsy indicator of mass (an objects resistance to acceleration). It is also a clumsy indicator of weight. The point being, do we know what the hammer is made of? Is it made of a lighter alloy than a Gieselle and so needs more volume to make the same weight? It could even be lighter than a Gieselle - and even though it has more volume the total system's mass is the same because it is propelled to the firing pin with more acceleration from spring tension (F=ma).

To be fair to 52', without any other information we can only go by the hammers shape and guess the amount of force that is likely to be impacting on the firing pin (inertia). To be fair to the manufacturer, it is only a guess. In the absence of engineering specs we can only go by personal experience and forum feedback. Manufacturers only list the weights needed to activate the stages of trigger release, not the weights of components or more importantly, the forces of inertia that result in what 52' is talking about.

We are using heuristics such as shape, price and brand equity to conclude a result. It remains an educated guess at best.

You won't know for certain until you actually try one.

if its made from anything lighter than steel it won't hold up, most aftermarket triggers use heavier hammers in order to be able to use lighter springs and still achieve reliable primer ignition
