General advisements:
*AR grips with extra tang may not fit.
*When attaching accessories to the handguard M-lok slots, avoid using screws with Loctite, as it can easily strip the polymer slots. Use screws without Loctite for best results.
*Handguard with 16" barrel my inhibit use of certain suppressor mounts.
