Excellent combo - Aero Precision M5E1 Upper Receiver and KeyMod Handguard Combo Gen 2

This upper and hand guard look absolutely amazing. Very pleased with the overall quality and look. A lot of upgrades have been done to the receiver making the removal of the dust cover, forward assist and hand guard easier than ever. There is also a set screw under the rear take down pin which allows for custom tuning of the upper and lower to stop rattling.
