The Battle Arms Xiphos series of firearms are purpose-built as the next generation, blow-back AR style pistol caliber firearms. The heart of the firearm is the billet BAD-GS 7075-T6 aircraft grade aluminum receiver and free-float rail handguard with M-LOK attachment points at 3, 6 and 9 oclock positions. At 12 oclock is a full-length Picatinny accessory rail with our signature notch cut matching the upper receiver. Every firearm is equipped with a 4150 chrome-moly steel barrel and 8620 steel black nitride blow-back bolt for ultimate reliability and ease of cleaning. The Xiphos is outfitted with the RACK ambidextrous charging handle with monolithic handle and smooth side sliding latch that is built to take abuse. It is loaded with numerous enhanced components such as our extended magazine release, enhanced takedown/pivot pins for easy tool-less breakdown, one piece magazine catch, enhanced bolt catch, adjustable three position pistol grip and enhanced single side safety.
