I am trying to install some triangular handguards onto my DPMS DCM. It appears the new handguargs are not sized for the free float tube, and are to long.
1. Can I file the handguards down to fit, or are they simply not meant to fit over the float tube?
2. Concerning the length, are the handguards made to indusrty length, or are not meant to be installed with the trinagular end cap and rest directly on the front sight post?
