AIM7 FROGFOOT Linear Comp 4″

AIM7 FROGFOOT 4″ Modular Linear Compensator & Alpha-Cone Front Cap (1-1/8×28 Alpha)

The AIM7 FROGFOOT 4″ Modular Linear Compensator & Alpha-Cone Assembly is a precision-engineered blast redirection system designed for lightweight versatility, structural concentricity, and seamless 1-1/8×28 (1.125×28) Alpha-pattern compatibility. Crafted entirely from premium aerospace-grade 6061-T6 aluminum and protected by a durable matte black hardcoat anodized finish, this modular setup delivers forward-directed blast management without adding unnecessary front-end weight.

Engineered specifically for smaller caliber platforms—including .22 LR, 5.7×28, and .223 / 5.56 NATO—this assembly pairs our 4-inch modular compensator extension tube with the blast-shaping Alpha-Cone front cap to drive concussive sound, flash, and expanding propellant gases straight downrange away from the shooter.

Key System Features

• Alpha 1-1/8×28 Compatibility: Threaded precisely to the 1.125×28 TPI standard across internal and external interfaces for universal fitment with popular Alpha-pattern adapters and modular muzzle components.
• Focused Blast Redirection: The Alpha-Cone front cap directs concussive muzzle wave and escaping propellant gases linearly downrange, preserving peripheral situational awareness.
• Featherweight T6 Aluminum: Machined from solid billet 6061-T6 aluminum to keep front-end muzzle heft down to an agile 3.0 oz while sustaining high operational heat and muzzle stress.
• Uniform Outer Profile: Engineered with a slim 1.290″–1.291″ OD for a flush, snag-free transition under slimline handguards and modular mounts.
• Hardcoat Anodized Shield: Type III hardcoat black anodized finish provides maximum resistance against carbon buildup, scratching, and environmental corrosion.

Important Disclosures & Compliance

• Policy & Classification Compliance: THIS ITEM IS NOT A SILENCER, SUPPRESSOR, OR NFA COMPONENT. It is strictly a non-baffled linear compensator extension and blast-forwarding device designed exclusively for directional concussion management. It contains no internal acoustic baffles, dampening media, or sound-muffling components, and does not diminish or suppress the sound report of a firearm.
• Fitment & Concentricity: Always inspect host barrel concentricity, adapter thread seating, and projectile clearance with an armorer’s alignment rod prior to live fire. Installation by a certified gunsmith or experienced armorer is strongly recommended. Always confirm firearm is unloaded, safety engaged, and chamber empty before mounting.
• Legal Responsibility: The purchaser assumes all responsibility for verifying compliance with applicable local, state, and federal firearms laws and regulations.
• California Proposition 65 Warning: This product may contain trace chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
