Sons of Liberty M4 — Direct Impingement, Ambi-Safety, B5 Hardware (Compact, Tactical-Ready)

Meet the Sons of Liberty M4: a lean, mean AR-style platform that won’t argue about your accessory choices. Built around a tried-and-true direct impingement system and packed with practical upgrades, this rifle is ready for range days, rigs, or whatever project build you’re scheming.

Quick, cheeky summary: dependable guts, modern controls, and parts you actually want to touch.

Why buyers like it

• Direct impingement action — classic AR cycling that’s easy to maintain and familiar to most shooters.

• Quick ambidextrous safety (50° throw) — faster, cleaner manipulations whether you’re lefty, righty, or just impatient.

• B5 Bravo stock — comfortable, rugged, and adjustable so the rifle fits you, not the other way around.

• Button Cut, V2 profile threaded barrel — slim but strong profile with threading for your muzzle device of choice.

• L89 Drivelock handguard — secure mounting, low profile, and plenty of real estate for accessories.

• B5-P23 grips — ergonomic texture and shape that make long range sessions less hand-cramp-y.
