The M33 is built to fit the M16/AR15 carbine. The handguard provides 2 mounting rails, complete with thermal rubber rail covers and heat shields. No tools or gunsmithing required for installation.
One thermal rail has been cut into two pieces to allow a M3 light to be mounted with the remaining rail being covered. When both pieces are placed on the rail they fit together nicely. $43.00 SHIPPED to CONUS or trade for a quality vertical foregrip or other quality AR parts. SPF
