Strike Industries Blast Shield for A2 Birdcage Flash Hider Review
What are some common accessories to add to the Strike Industries Blast Shield for A2 Birdcage Flash Hider?
- Carbon Removers/Solvents: Regular cleaning with appropriate solvents helps maintain the interface between the A2 birdcage and the Blast Shield, ensuring consistent fit and function.
- Brushes & Scrapers: Some kits include specialized tools or scrapers designed to remove carbon buildup from specific areas of muzzle devices and bolt carriers. These help ensure the Blast Shield's quick-attach mechanism functions smoothly.
- Bore Cleaning Kits: A comprehensive bore cleaning kit will help maintain the barrel, which is essential for overall firearm performance. While not directly for the shield, a clean bore and muzzle contribute to the consistent performance of any attached muzzle device.
- Muzzle Device Wrenches/Armorer's Tools: An armorer's wrench is vital for correctly installing, timing, and securing the A2 birdcage flash hider to the barrel. A properly secured and timed A2 birdcage ensures the Blast Shield mounts correctly and functions as intended. Some armorer's wrenches have specific fittings for A2 flash hiders. It's important to use the correct tools to avoid damaging the firearm or the muzzle device.
- Heat Resistant Gloves: Heat-resistant gloves, such as those made with materials like CarbonX or specialized leather, allow for safer handling of the firearm and the Blast Shield if it needs to be removed while still hot.
- Heat Resistant Pouches/Covers: For operators who might need to remove and stow a hot blast shield quickly, a heat-resistant pouch or cover can prevent burns to personnel or damage to other gear.
- Degreasers: Before installing the A2 birdcage, ensuring the barrel threads are clean and free of oil or grease is important for proper torque and seating.
- Thread Lockers (for A2 Birdcage): While not applied to the Blast Shield's QD mechanism, ensuring the A2 birdcage itself is securely attached to the barrel is paramount.
