Easy to install upper receiver handguard combo looks great too! - Aero Precision M4E1 Upper Receiver and MLOK Handguard Combo

Aero Precision knocked it out of the park with this combo. Its so easy to mount your barrel to the enhanced M4E1 upper with no gas tube timing necessary. Another plus is it comes with the barrel nut wrench which mounts to your torque wrench with 1/2" drive at no additional cost (Geissele, cough). It has the Mlok slots at 3,6 and 9 o'clock positions. Once I completed my rifle it came out looking great when paired up with the M4E1 lower receiver from Aero Precision. So far I got about 400 rounds through my 15" handguard combo and its exceeded my expectations.
