CGS Helios QD TI

Overview of the CGS Helios QD Ti

The CGS Helios QD Ti is a refined, titanium-built system designed for compact, quick-attach performance. It is primarily engineered for 5.56mm platforms. The model features CGS’s specialized “varying core diameter” design. This structure improves internal gas flow and helps maintain consistent operation. It keeps the strength of the original Helios QD but delivers a noticeably lighter titanium version.

Expanded Bore Design

The unit includes a .36-inch bore, which increases caliber compatibility. The broader internal space naturally reduces gas blowback. This helps create a smoother overall cycle on supported platforms. The internal tapers are carefully shaped to reduce the chance of endcap or baffle contact. CGS recommends a 10-inch minimum barrel length for ideal function on 5.56mm systems.

Titanium Construction Advantages

A key highlight of this model is its balance of strength and reduced mass. The Helios QD Ti is built from Grade 5 titanium, allowing it to retain strong structural integrity while cutting unnecessary weight. It provides the same sound-reduction performance found in other CGS designs but with a slimmer profile. The modular sealed end-cap system adds additional flexibility for different platform setups.

Dimensions and Performance Rating

The unit measures 7.2 inches from the rear hex to the front hex. It weighs about 9.6 ounces, although the weight may vary with different endcaps or attachments. With a 1.75-inch diameter, it maintains a stable forward balance suitable for modern rifle layouts. The model is rated for use up to 300 Norma Magnum, reflecting its durable titanium construction.

Included Components

The package contains several compatible parts. These include 1/2×28 and 5/8×24 rear-thread caps. It also comes with sealed front endcaps and a 1.375×34 adapter ring. These components expand compatibility within its intended technical category.
