*Please note - This handguard uses the BAR interface and does not work with a standard barrel nut. If you are using the M4E1 Enhanced Upper Receiver, no additional pieces are needed. If attaching this handguard to a standard upper receiver, you must use a BAR barrel nut (select check box above).This handguard is specific to the AR15/M4E1 platform. It is not compatible with the M5 .308/M5E1 platform.

I really like this Aero Precision Handgaurd. It seems very well made and looks great on my Aero Precision rifle. Tom's Tactical did a great job and got it shipped to me super fast.


This was a great find. Great price, easy installation, and a rock solid product. I wish I would have found Tom's sooner, could have saved a lot of money.


Very happy with the quantum, Good on weight, better on price. I wish it had a QD slot but you can't ask for too much at this price point solid handgaurd fit perfectly on my Aero upper and BAR barrel but.


Very solid, fit and finish are great as is typical with Aero stuff. Not quite lightweight their their enhanced handguards though, just as a heads up. Order processing and shipping was quick as can be too, always a plus


Great price and fast delivery from Tom.s This is the first time I have used the Quantum handguard and I am impressed. Very light weight and fit perfect on the Aero upper with the Aero barrel nut.
