Aero Precision M4E1 AR-15 Upper Receiver + Gen 2 Free Float Rail Combo Set

This item may have cosmetic blemishes. Functionality is not affected.

This Upper Receiver Handguard Combo now includes the new Gen 2 Enhanced Handguard!

Key features include the addition of quick disconnect sling sockets, enhanced milling design for grip and visual appeal and a new profile for the picatinny top rail.

The state of the art M4E1 platform starts with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Since the rail mounting surface and upper are of the same forging, not only is it a stronger system, but it also provides for easy installation of the gas tube with a pre-aligned gas tube hole. Additional lightening cuts save weight and allow for more efficient cooling.

Easy barrel installation - Simply insert your barrel assembly into the M4E1 upper and tighten it using the provided barrel nut and wrench. Then slide your rail on and tighten the screws. Within minutes you have a modular, free-floated rail.

When it comes to great USA made products at an affordable price it's hard to beat Aero and Tom's Tactical. Couldn't find a blemish on either the receiver or hand guard. The enhanced upper made it a breeze to install my barrel and the hand guard marries perfectly and looks great. Highly recommend this setup! Tom's had the best price by far with free and prompt shipping. Thanks!


The product- I had a hard time finding any blemish, and it went together fine and functions like it's supposed to. This was my first purchase from Tom's - it probably won't be my last - great price , and fast shipping .


Shipping was really fast. Came in and I could t be happier.


Great product! shipped next day. Couldnt find the blem..
