Susismith's RAHE R-20 / AR15 / M4 5,56mm Muzzle Cover

The RAHE R-20 Muzzle Cover is a simple, rugged solution to protect your rifle’s crown and bore from contamination and corrosion. Made from durable, weather-resistant polymer, the cover fits snugly over most standard 5.56 mm AR-style muzzles and stays put under movement or vibration while remaining easy to install and remove — even with gloved hands. Its slim profile preserves clearance and won’t interfere with optics or slings while mounted.

Ideal for patrols, range transport, vehicle kits and storage, the cover prevents abrasive grit and moisture from entering the barrel, helping maintain accuracy and shortening cleaning time after exposure to harsh environments.

Key features:

• Snap-fit plastic cover for 5.56 mm AR15 / M4 muzzles
• Fits most standard AR-style muzzles — secure, low-profile fit
• Protects bore and crown from mud, dust, and moisture
• Durable, weather-resistant polymer construction
• Easy on/off — usable with gloves
• Lightweight and compact for kit storage

The RAHE R-20 5.56mm Muzzle Cover is a small, mission-focused accessory that protects your rifle where it matters most — the bore and crown — so your weapon stays ready and accurate in the field.
