About LWRC
LWRC makes piston driven ARs like the M6 and IC series. Their short stroke piston keeps gas and carbon out of the action.
Founded 1999, Cambridge, Maryland, Made in USA · Gas piston · Military and LE supplier
Why LWRC
LWRC began in 1999 in Virginia as Leitner-Wise Rifle Company and moved to Cambridge, Maryland in 2008. It's a piston gun maker, and its rifles have gone to the Pentagon, Jordan's military and SWAT teams.
The short stroke, self regulating piston keeps gas and carbon off the bolt and receiver, so the action runs cooler and cleaner. The M6 and IC rifles are the AR-15 line, with REPR and SABR in .308.
Lowers are the part builders buy most, at around $600 against roughly $215 for the typical lower. Many of those are complete IC lowers, not bare receivers.
Pistons add weight up front and cost a lot more than direct impingement, and piston uppers use LWRC's own parts. We'd buy one if you run suppressed or short barrels and hate cleaning, not for a budget build.
- LWRC rifles use a short stroke, self regulating gas piston that keeps gas off the internals, cutting heat and carbon fouling.
- The M6 series is LWRC's main line.
