If you are on the market for a lightweight minimalist handguard, the Aero Precision Quantum M-LOK handguard is the one for you. It features a smooth octagonal shape with M-LOK attachment points on every flat, so you can easily adapt this rail for any situation. The rigid M-LOK attachment system allows you to quickly rearrange rail sections, lights, grips, bipods, and more without the extra weight of full length rails. This free float handguard is made from 6061-T6 aluminum and has a hardcoat anodized black finish that can withstand harsh weather and hard use. The built in anti-rotation tabs combined with the proprietary locking system on the M4E1 enhanced upper receiver ensure that this rail won’t loosen over time. The slightly larger 1.78” inside diameter is designed to be used with most 1.5” suppressors and muzzle devices. The 12” length is also capable of fully covering mid-length gas systems as well as partially cover rifle length systems. The Aero Precision Quantum AR-15 handguard is the perfect addition to your M4E1 enhanced upper receiver.
