Tensioner

2A Defense hand-fits all of its uppers and lowers providing the tightest tolerances between the two parts. However a time may come after lots of use that you may wish to add some tension to the uppers takedown lug for continued snug support. To achieve this we have added a lug tensioner to the lower which allows the operator take up the slack if needed.

Integrated Rail Platform
Integrated Rail Platform Kit

Integrated Rail Platform

True to its namesake, the Integrated Rail Platform (IRP) upper receiver is a rigid design allowing you to mount your optics, lasers, and other sighting devices anywhere along the top rail without impediment from delta rings and rail bolt-up systems. This minimizes accuracy issues related to misaligned, loose, or improperly installed rails found from other manufacturers, and gives you the strongest platform available in an AR pattern rifle.

 

Interchangeable Rail Panels

The IRP Upper Receiver boasts removable rail panels at the 3, 6, and 9 o’clock positions. Simply unscrew the mounting screws on the side you need to swap, slide out the existing panel and you’re ready to install the rail section you need. This system allows you to easily adjust from a lightweight slab-sided rail, to a mixed combination of our panels to fully accessorize to your mission.
