Excellent upgrade, but buy better grade allen bolts! - Midwest Industries MP5 Clones Mil-Spec Top Rail Handguard, M-Lok Compatible

Excellent upgrade to your HK and Cloned Firearms. The only reason for a 4star and 5stars is the two smaller Allen screws will not be able to be torqued to the specific they recommend without stripping the Allen heads! I used a professional Gun smithing torque stick for that job and it was the correct torque specification and correct size Allen bit!!! I’d recommend go to your local hardware store and buy a better grade Allen screws! I’d say stainless ones would be hard enough.
