CGS Helios QD - DEMO
Capitol Armory is licensed in all suppressor-friendly states. Form 4 or 4473? Read 4473 vs. Form 4 Suppressors. Your choice during checkout. See how suppressors direct to your door works or choose to send to your local dealer.
Under ATF's October 9 policy, you can buy a suppressor on a 4473 in some states. We still recommend a Form 4: it stays compliant if the policy changes, and ATF approvals come back in days.
USED CGS HELIOS QD SUPPRESSOR
The CGS Helios QD is a 3D printed 718 Inconel rifle suppressor optimized for 5.56mm rifles and carbines. It has a .36 bore to reduce backpressure and allow use with 7.62 caliber projectiles, and it is rated up to 300 Norma Magnum. CGS's Varying Core Diameter design reduces sound and flash while keeping point of impact shift minimal, and the taper interface between the suppressor and muzzle device prevents carbon lock. It is full auto rated with no barrel length restrictions. The rear uses a HUB/Bravo (1.375x24) interface. This kit includes two direct thread mounts, a compatibility ring for third-party Bravo mounts, and two front caps. The flow-through front cap reduces backpressure further.
USED CONDITION
This suppressor has minor handling marks, a little burnt plastic residue on the DLC finish, and minor carbon fouling. The round count is estimated at under a few hundred rounds. Images are not of this specific suppressor and may be generic images.
