The LMT Classic M203 receiver is the receiver for the LMT 40mm M203 launcher in the barrel-mounted M16/M4 design. It is supplied as a receiver only, so the barrel, front mount and sight are bought separately. LMT lists the 40mm launcher caliber and a barrel-mounted style for this part, which makes it the starting point for building a classic under-barrel launcher. Builders choose it when they want the traditional M203 layout rather than a rail-mounted version.

Key Specifications

• The launcher caliber is 40mm, the standard size for M203-pattern launchers.
• The mounting style is barrel mounted, in the M16/M4 under-barrel design that the classic M203 uses.
• The part is supplied as a receiver only, without a barrel, front mount or sight, so you can choose each to suit the build.
