R5 RGP (Remington Gas Piston) is a carbine that was designed and manufactured by Remington Arms.[4][5] It is an AR-15 type rifle which uses a unique mid-length gas piston operating system in an attempt to improve the reliability of the weapon,[6] and featured a monolithic upper, as the upper receiver and handguard were machined as a single piece.

The R5 was available from Remington until some time prior to 2016. A Remington representative compared it to the expensive HK 416, and that how the R5 was double the price. It is assumed that the weapon did not sell as expected and was thus removed from offer.
