Advantages Over MA5C
One advantage is that the BR57 jams much less often than the MA5C, its greatest competitor. Second, the clip is larger, allowing for fewer reloads. Second, the BR57 is also capable of three firing styles, whereas the MA5C is only capable of one. This allows for a better weapon in multiple types of scenarios. Lastly, this weapon has an efficient silencer capability through the use of the M34 Surpressor.

Disadvantages
The BR57, however, still has a few flaws. First, as with most firearms, it is still capable of jamming. Second, the weapon can has trouble penetrating armor, as the rounds were designed. Lastly, at long range, the BR57 does not have the capability desired.

Design Changes from BR55
The BR55HB FA has 3 different styles of fire: semi-auto, 4-Shot burst, and full-auto, whereas the BR55 only had the semi-auto and burst options. The FA also fires four shot bursts instead of the usual three, and its barrel is about four inches longer than the BR55's, allowing for greater accuracy.

Magazine
The magazine is slightly larger than the BR55's, as it carries 36 rounds instead of 50. To compensate, the magazine's spring system is a small upgrade to the original, preventing most malfunctions. Also, unlike the standard BR models, the magazine enters from the top of the stock, allowing for fewer jams. However, the bullet used is still the same.
