Builders Parts (BP) (ビルダーズパーツ Birudāzu Pātsu?) is a line of plastic accessories and effect parts kits for Gunpla from the Gundam meta series. Most of the kits are made in 1/144 scale and are compatible with High Grade and Real Grade kits, but some are non-scaled or 1/100th scale. The BP line is split into three lines: System Weapon (BPSW), System Base (BPSB) and Builders Parts HD (BPHD).
Reissues from 2019 onwards will bear the blue Bandai Spirits logo.
System Weapon[]
System Weapon (BPSW) (システムウェポン Shisutemu Uepon?) consists of 1/144 scale weapons that are more detailed than those supplied in regular Gunpla kits and can be customized to any configuration. Each set includes a display rack and extra hand parts. These kits are manufactured in China or Vietnam.
