Questions & Answers
Will this fit an m16a4? Expert Answer

The Troy Modular AR-15/M4/M16 Rail Drop in Forend will fit any AR platform rifle that uses a mid-length gas system, 2-piece handguards, and a triangle front cap. Most M16 style rifles with an 18" barrel or longer use a rifle length gas system meaning this forend wouldn't be compatible.

Will this fit a sig sauer ar15 2.23/ 5.56 m400 Expert Answer

The Troy Modular AR-15/M4/M16 Rail Drop in Forend is a 2-piece handguard that only fits rifles with a delta ring and handguard cap. It would not be compatible unless you install a delta ring and handguard cap on your rifle.
