The Aptus evolved from the popular Paratus rifle and features the same patented internal recoil technology and quick take down rifle technology. Chambered in 5.56mm the Aptus is Latin for ready. The patented internal recoil system eliminates the standard buffer tube/spring associated with most AR style rifles allowing it to be fired with stock folded. The rifle can be assembled in less than 60 seconds without the use of any tools. This tactical rifle comes with extraordinary custom detail and outstanding quality. It has an ambidextrous safety bolt catch and a left side non reciprocating charging handle. This patented quick take down rifle is designed for compact portability and discreet carry.
