The most exciting multi-purpose firearm available, and the only non-banned, American-made Bullpup on the market! Use it for home defense; varmints, Saturday afternoon plinking - it does it all! Built by Bushmaster to our highest quality standards with Extended 2 Year Parts and Labor Warranty, Bushmaster's M17S Bullpup is a lightweight, short stroke piston, gas operated, self compensating, air cooled, magazine fed, semi-automatic rifle. In American Survival Guide, Paul Hantke wrote: "Short barreled rifles and smaller carbines designed from scratch have been around forever, and the next generation of design, The Bullpup, puts it all together in the most compact package yet". And, "the shortest, handiest, yet legal little rifle around". The gun "just seems to win over everyone that handles or fires it."
Though it does include 25 meter open sights in the see-thru channel under the scope rail, the Bullpup is designed to be used with any popular scope, red dot sight, or night vision device, and its Picatinney type rail will accept them all. The .223 Rem. caliber, 21.5" barrel - hard chrome lined in both bore and chamber - offers competition accuracy in a gun with a total length of only 30". This beautifully simple rifle is easy to maintain - it's hinged push pin system quickly separates the upper and lower receivers allowing full access to all moving parts. Bushmaster's M17S Bullpup is shipped complete with a black web sling, a 10 round magazine, operation manual and warranty registration card - all in our foam lined, hard sided, Bushmaster carrying case.
All parts for the Bushmaster M17S Bullpup are readily available.
