The Boss-25 from Legacy Sports is an AR-style semi-automatic 12-gauge, and like any magazine-fed shotgun its practical capacity depends entirely on having spare magazines ready. This factory 10-round magazine is a serious step up from the flush magazine, which matters for 3-gun stages, defensive drills or simply extending a range session between reloads. Factory magazines are the safest choice for a shotgun because shell rim geometry and feed-lip tension are finicky, and Legacy builds these to the Boss-25's exact specifications. Load it with the shells the shotgun is set up for and it drops in and locks like the original.
