The Angstadt Arms Reticent 360L is the long, 8-inch version of the company’s .36 caliber multi-platform titanium suppressor, rated for pistols up to 9mm and rifles up to .360 caliber (brand part no. AARET36LTB). The L stands for Long, and the extra internal volume gives gases more dwell time for a quieter, lower-frequency report. Angstadt Arms prints it from Grade 5 titanium using direct metal laser sintering, which holds the weight to 8.5 ounces without a mount. It is HUB compatible and includes a 1/2×28 direct thread mount, so one can can move between a 9mm carbine and a rifle. It suits a dedicated host where the quietest shot matters more than length.

Key Specifications

• Pistol calibers are rated up to 9mm, which covers common handgun and pistol-caliber carbine loads.
• Rifle calibers are rated up to .360 caliber, a wide range for one titanium can.
• Length is 8 inches, the extended size that gives gases more room to slow and cool.
• Diameter is 1.55 inches, a slim tube for a can with this much internal volume.
• Weight is 8.5 ounces without the mount, light for a full-length multi-caliber suppressor.
• Weight is 11 ounces with the mount, the figure to use when planning a complete rifle.
• The body is Grade 5 titanium, a strong alloy that keeps weight off the muzzle.
• It is made by direct metal laser sintering, which allows internal gas paths that machining cannot produce.

• The mount is HUB compatible with a 1/2×28 direct thread mount included, so standard HUB adapters also fit.
