Thread pattern: 1/2″-28 TPI — the standard AR-15/5.56 muzzle thread in the U.S., so a direct-thread or 1/2×28 mount will fit barrels with that thread.

“Ghost” name: several manufacturers use the name Ghost (Dead Air’s Ghost family is the most common modular product line). There are multiple Ghost models (Ghost-M, Ghost-45, Ghost fixed mounts and mounts for Ghost-M/Wolf series) and also other companies’ 5.56 cans or flash-cans called “Ghost” or “Ghost-style.” Make sure you’ve got the exact manufacturer/model.

What the “5.56” implies: rated for 5.56/.223 family (supersonic vs subsonic performance varies by can and baffle configuration). Confirm the suppressor’s rated calibers and full-auto rating if you need it for rapid fire.

Mounting options: many Ghost suppressors use modular mounts or fixed 1/2×28 direct-thread mounts (Dead Air offers dedicated 1/2×28 fixed mounts and piston/mount accessories).

Exact model & manufacturer (Dead Air Ghost-M, Ghost-45, Griffin GP-5, or a generic/replica?). Different models have different lengths, weights, bore sizes and material (Ti, stainless, aluminum).

Specs: length, weight, diameter, material, rated cartridges, thread/mount type, and whether it’s full-auto rated. I can pull a spec sheet for the exact model.

Legal & import: suppressor laws vary widely by country/region — check local regulations before purchase or shipment. (If you want, tell me your country and I can look up rules and local availability.)
