The LoneStar Future Weapons RM277 is an American battle rifle developed by Texas-based firearms manufacturing venture LoneStar Future Weapons. It is chambered in a proprietary ammunition, polymer-cased 6.8mm TVCM manufactured by LoneStar's parents company, True Velocity. It was unveiled in 2021 and submitted for evaluation by the United States military for the Next Generation Squad Weapon (NGSW) competition to find a design to replace the M4A1 in military service. The design was originally conceived by General Dynamics in 2019 before LoneStar took over development of the project. In mid-2022, the RM277, along with other NGSW submissions, were rejected in favor of the SIG-Sauer MCX-SPEAR.

Like the MCX-SPEAR, the RM277 is also designed to use the Delta P Brevis III 3D-Printed suppressor in normal operation. Due to the weapon's prototype status, it is believed only a handful of firing examples were ever produced.
