Fulton Armory HUB Mount Brings M14 Threads Into the Suppressor Era

Fulton Armory has released an M1A/M14 HUB Mount that adapts the rifle's old .595x32 muzzle threads to the 1.375x24 HUB interface now common across the suppressor industry, giving owners a more direct path to running a can on an M14-pattern rifle.

Snapshot

GarandThumb's review walks through the Fulton Armory mount's specs, fitment and installation, noting it solves the M1A's longstanding thread-compatibility headache for $89.95. The piece stresses this is a spec-based review, not range-tested data, and that the mount is one piece of a larger suppressor conversion rather than a complete fix.

Key points

• Specs: Product FA-M-186 is hardened 4140 steel with a nitride finish, converting .595x32 rifle threads to 1.375x24 HUB, priced at $89.95 with an optional $12.95 wrench.
• Fitment: It works on 18.5-inch and 22-inch barrels; 18-inch models fit too, but the mount must be removed for gas-piston cleaning, meaning careful reinstallation and alignment checks each time.
• Front sight tradeoff: Removing the traditional flash suppressor assembly can eliminate the rifle's front-sight mounting point, so iron-sight users may need a gas-lock front-sight base not included with the mount.
• Gas system: GarandThumb notes the mount doesn't address M1A backpressure issues; owners may need an adjustable gas plug or lower-backpressure suppressor to avoid harsh cycling.
• Alignment: The article stresses checking suppressor bore alignment with a rod after installation, since damaged threads or debris can cause a costly baffle strike.

Quick take

GarandThumb's assessment is that the Fulton mount is a sensibly priced, well-made answer to the M1A's outdated thread pattern, but it's best suited for owners who already understand the platform's gas system and have a sight-replacement plan, not a plug-and-play suppressor solution.
