Frequently Asked Questions

What is the SIGH conversion kit?

The SIGH conversion kit from Reap Industries transforms a standard AR-15 into a bullpup configuration. It allows users to maintain their existing AR lower and upper receivers while significantly reducing the overall length of the firearm without requiring NFA paperwork.

How is the SIGH conversion installed on an AR-15?

Installation involves attaching the SIGH unit to a milspec AR lower receiver, using its integrated pins along with the standard AR lower pins. An AR upper receiver is then mounted, and the trigger bar system is adjusted for proper function. The process requires precise measurements and alignment.

What are the benefits of the SIGH AR conversion?

Key benefits include a drastically reduced firearm length, making it more maneuverable, and the fact that the SIGH unit is not an FFL item, allowing direct shipping. It also adds minimal weight (12 oz for the unit) and features a lifetime warranty.

Are there any potential issues with the SIGH conversion?

Some users may experience issues with trigger reset if the unit's screws are overtightened. Additionally, the lack of a traditional shell deflector on some compatible uppers, like the BRN180, can cause ejected casings to hit the shooter's forearm in certain shooting positions.
