What are the benefits of the SCAR25 lower versus the factory FN polymer lower?

The SCAR25 lower is made of billet aluminum or magnesium (depending on variant). Our lowers are not prone to flex (commonly observed with the FN polymer lower) this increases shot-to-shot accuracy. Additionally, the Special Forces community has experienced problems with the polymer lower swelling in wet environments; our metal lowers do not have this issue. Finally, SR25/M110 pattern magazines are readily available, inexpensive, and have interchangeability between common 7.62×51 battle rifle platforms (FN factory magazines are less cost-effective, not readily available, and are proprietary to the SCAR weapon system).
