Question: Which company manufactured the rifle that the Bundeswehr replaced in 1997? Passage:The Heckler & Koch G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch in Germany as a replacement for the heavier 7.62mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1997, replacing the G3. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine. The G36 was made with the extensive use of lightweight, corrosion-resistant synthetic materials in its design; the receiver housing, stock, trigger group (including the fire control selector and firing mechanism parts), magazine well, handguard and carry handle are all made of a carbon fiber-reinforced polyamide. The receiver has an integrated steel barrel trunnion (with locking recesses) and a nylon 66 steel reinforced receiver. The standard German Army versions of the G36 are equipped with unique a ZF 3×4° dual optical sight that combines a 3× magnified telescopic sight and an unmagnified reflex sight mounted on top of the telescopic sight. Widely distributed, it has been adopted by over 40 countries and prompted other nations to develop similar composite designs, such as the FX-05 Xiuhcoatl.

Question: In what year was the house the Vogtei went to after the Lenzburg family established? Passage:The first mention of modern Hägglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromünster. In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned. Frederick I Barbarossa acknowledged the grants to the village in 1173. The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl. The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415. It was not until 1425 that Hägglingen, which was claimed by Lucerne, came under the authority of the entire Confederacy. It was first assigned to the district court of Wohlenschwil before it became an independent municipality from 1435-1712.

Question: When was the Brooklyn and Rockaway Beach Railroad founded? Passage:The New York, Bay Ridge and Jamaica Railroad was incorporated on November 20, 1875, to complete the work and operate the line to Jamaica, using the Brooklyn and Rockaway Beach Railroad (Canarsie Line) from New Lots to East New York and the LIRR Atlantic Avenue Division to Jamaica. The first piece, from the Bay Ridge Ferry (to South Ferry, Manhattan) to the crossing of the Brooklyn, Bath and Coney Island Railroad (West End Line) at New Utrecht, opened on August 23, 1876. Trains were operated over the BB&CI to Coney Island via trackage rights from this junction. Banker Austin Corbin incorporated the New York and Manhattan Beach Railway on October 24, 1876, to build a branch of this line to Manhattan Beach and extend it beyond East New York to Greenpoint and Hunter's Point. Corbin gained control of the New York, Bay Ridge and Jamaica Railroad on November 15, 1876. The NY&MB bought the eastern half of Coney Island from the town of Gravesend and renamed it Manhattan Beach.
