Details
The Cross Machine Tool UHPR Mod 2 HDX Handguard is a free float AR-15 rail built from 6000-series extruded aluminum with a patented 17-4PH cored stainless steel mounting attachment for a secure, tool-free-timed mount. At just 13 ounces with hardware included, this 15-inch rail is sized for 16-inch rifle builds.
- 6000-series extruded aluminum, Mil-Spec Type III Class 2 hard black anodized
- 7075 aluminum barrel nut, Type III Class 2 hard anodized
- 17-4PH cored stainless steel rail mounting attachment (patent pending)
- M-LOK slots on all 7 flat sides
- 4 nitrided steel QD sling sockets, 2 per side at 3 and 9 o'clock
- No barrel nut shims required for installation
- 1.315" internal diameter
- 13 oz total weight, including mounting hardware
- Made and assembled in the USA
Anti-rotate tabs time the rail to the upper receiver, and once installed the rail floats over the gas tube without any points of contact, keeping barrel harmonics free of handguard interference. Four nitrided steel QD sling sockets, two per side, give you rear and forward sling mounting without an extra accessory purchase. At 15 inches, this is the longer option in the UHPR Mod 2 HDX line, still sized for 16-inch rifles but with additional M-LOK real estate up front for lights, grips, or a bipod mount.
Cross Machine Tool builds precision-machined AR-15 components for shooters who need their rail to maintain zero, backing every rail with US-made construction and a veteran-owned commitment to quality control.

Great rail
by JT -
In my opinion, Cross Machine Tool makes one of the best handguards on the market right now. Especially for the price, even though I think they might have increased some, but what hasn’t. They’re nice and light, have a good mounting system, and I really like the qd sling mount cups that are steel inserts. Because a steel qd mount will eventually chew away at the softer aluminum. It’s just a nice touch that you never see on cheaper handguards. I have mounted a few of them onto BCM upper receivers, and they fit perfectly.
Nice handguard

Got it on sale during Memorial Day. Minor fitment issue with Anderson Manufacturing upper receiver - likely upper's fault, Andersons can have sloppy tolerances. Anti rotation tabs and top rail not aligned. Filed to fit, I made it work.
It's rather light, as advertised. It's also skinnier than an anorexic model. This can cause problems with certain M-Lok accessories at 10:00 and 2:00 interfering with accessories on the top rail, like BUIS. Most slim rails seem to have this problem though.
The mounting system is pretty nice and everything else is fine. Good for a light carbine build.
