Aero Precision Mod 4 HG by johnchip, Verified Owner, December 21, 2024
The Mod 4 brings some much needed upgrades over the Altas series rails. No barrel nut timing, steel reenforced qd mounts, 7 sided M-Lock, t marks, and a way better anti rotation system. I do not think it is worth the asking price and you mine as well...

Great upgrade by Andy R., Verified Owner, January 20, 2025
Got this to replace the Atlas R-One on my latest build. Super easy to swap out. No need for shims as the barrel nut doesn’t need to be timed. Handguard attachment is rock solid. Really pleased with this upgrade.

Outstanding quality by Jay, Verified Owner, October 23, 2025
Outstanding quality and well executed in design…not for 10.5 inch barrels…for 11.5 or bigger. No Shins, tighten down barrel nut and install gas tube and gas block, slide hand guard on and tighten up the screws. Done….very simple to install. The anodi...

One of the best FF Rails out there by Taz8654, Verified Owner, May 7, 2025
Things my second one of this rail. First one was black for my 6 ARC build, this one was green. I am happy that the anodizing wasn’t the typically shiny effect you see on a lot of other brands. I did have to make a relief groove where it locks up to t...

Product Info for Aero Precision Mod 4 AR Handguard

The Aero Precision Minimal Optical Deflection (MOD) 4 handguard seamlessly blends robust construction with an ergonomic form factor, ensuring no compromises between the two. Machined from 6061-T6 aluminum, the handguard is engineered with a focus on stiffness to drastically reduce deflection under load. It attaches to the upper receiver via a steel barrel nut, which also serves to significantly reduce point-of-impact shift when using an infrared laser aiming device under load.image

In addition to its premium engineering, the MOD 4 handguard offers several quality-of-life improvements. A full-length, 7-sided M-LOK™ interface allows the user to customize their build according to their preferences. The steel-reinforced QD sockets are a small but important detail, enhancing the sheer strength of the sockets and ensuring they do not wear prematurely when interfaced with standard steel QD sling attachments. Installation of this handguard is simplified at the barrel nut, as the need for timing has been eliminated, and the barrel nut lug pattern matches mil-spec castle nuts, removing the need for specialty tools. Finally, the inclusion of two anti-rotation set screws adds redundancy and ensures a more tailored fit when the handguard is used with third-party upper receivers.
