Description
Top Rail
The MIL-STD 1913 Picatinny top rail runs the entire length of the upper receiver and is ready to accept your optics of choice.
Hand Guard
The smooth SDP handguard is slim and contours with the palm for control and for precision maneuvers in close quarter engagements.
Buffer Tube Plate
The SDP buffer tube has been carefully crafted with ample room for a small type 11.1v lithium polymer battery.
CCS
The two-position Compact Carbine Stock provides enhanced stability in both the collapsed and extended position over traditional telescoping stocks.
Metal Alloy Receivers
Metal alloy receivers provide a strong and lightweight foundation for the AEG and are responsible for and housing the KRYTAC Nautilus Gearbox.
INTERNAL OVERVIEW
MOSFET
An onboard MOSFET built into the Nautilus Gearbox regulates battery current to protect the trigger contacts. This system helps ensure the longevity of the gearbox while providing consistent performance with various battery types.
Padded Cylinder Head
The padded cylinder head helps soften and absorb the shock transferred to the gearbox while in use, it also provides proper angle of engagement between the piston and sector gear.
Reinforced Piston
The KRYTAC Reinforced Piston is both strong and lightweight, durable to handle the high cyclic rate of the Nautilus Gearbox and light to conserve energy.
Rotary Hop Unit
The KRYTAC Rotary Hop-Up unit is designed to optimize the range and accuracy of your AEG. The rotary adjustment wheel is precise and definitive, each click position is numbered with a tactile and audible feedback when adjusting.
Easy Spring Change
The Nautilus Gearbox features an easy spring change that does not require the full disassembly of the gearbox.
