The Precision Armament TiTrex 300SD is the Severe-Duty, Inconel-core version of the TiTrex 300 suppressor (Precision Armament part no. R10232). Precision Armament describes it as the hard-use variant, optimized for high-temperature, high round-count firing schedules, and says it adds about 4.2 ounces over the titanium model in exchange for that durability. It uses the X-CORE exchangeable core design inside a serialized XBand containment housing, so the core can be replaced without touching the serialized part. It is aimed at high-volume precision and PRS shooting, heavy AR use and training.

Key Specifications

• The caliber is .30 caliber, and Precision Armament rates the TiTrex line for .300 RUM with no barrel-length restrictions.
• The core is Inconel 718, chosen for heat tolerance on long strings of fire.
• Weight is 11.4 ounces for the body and 13.4 ounces with the mount and front cap.
• Length is 5.9 inches for the body and 6.2 inches with the mount and front cap, and outside diameter is 1.65 inches.
• The mount is HUB compatible and the front is compatible with SilencerCo Bravo-pattern front attachments, so common mounts and front caps carry over.

Frequently Asked Questions

How does the TiTrex 300SD differ from the TiTrex 300Ti? Precision Armament calls it the Inconel, hard-use variant of the TiTrex 300, about 4.2 ounces heavier and optimized for high-temperature, high round-count firing schedules.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.

What is the XBand housing? It is the serialized 17-4 stainless steel containment housing with an H900 heat treat that supports the blast chamber, so the exchangeable core can be replaced without altering the serialized part.
