The Kel-Tec Sub 2000 is a unique and popular pistol-caliber carbine known for its foldable design and ease of use. However, one aspect that often sparks questions among owners and prospective buyers is the charging handle. This guide dives deep into the Kel-Tec Sub 2000 charging handle, addressing common concerns, modifications, and troubleshooting tips.
Understanding the Kel-Tec Sub 2000 Charging Handle Mechanism
Unlike many firearms, the Sub 2000's charging handle isn't a traditional reciprocating handle. Instead, it's a non-reciprocating design, meaning it doesn't move back and forth with each shot. This contributes to the gun's smooth operation and reduced felt recoil. The charging handle's primary function is to lock the bolt back after the last round and to chamber a fresh round when needed.
How the Charging Handle Works:
- Charging: To charge the weapon, pull the charging handle fully to the rear. This strips a round from the magazine and chambers it.
- Releasing the Bolt: To release the bolt (allowing it to go forward), simply push the charging handle forward.
This simple, intuitive system is a key element of the Sub 2000's user-friendly design.
Common Issues and Troubleshooting
While generally reliable, some users experience minor issues with the Sub 2000 charging handle.
Problem: Stiff Charging Handle
A stiff charging handle can be caused by a few factors:
- Break-in Period: New Sub 2000s often have a stiffer charging handle initially. This typically improves with use.
- Lubrication: Insufficient lubrication can lead to increased friction. Applying a high-quality gun lubricant to the charging handle mechanism can resolve this. Always consult your owner's manual for recommended lubricants.
- Dirt or Debris: Dirt, dust, or debris can accumulate in the mechanism, hindering smooth operation. Regular cleaning is essential.
Problem: Charging Handle Failure to Lock Back
If the charging handle fails to lock back after the last round, it may be due to:
- Magazine Issues: Ensure you're using a properly functioning magazine. Bent or damaged magazines can cause feeding problems.
- Ammunition Problems: Using ammunition that is not compatible with the firearm can lead to malfunctions.
- Mechanical Issues: This could indicate a more serious problem requiring professional attention from a qualified gunsmith.
Modifications and Upgrades
While the factory charging handle generally performs well, some aftermarket modifications exist:
- Enhanced Charging Handles: Some manufacturers offer charging handles with improved ergonomics or a larger surface area for easier manipulation. These modifications are primarily for enhanced comfort and control. Always ensure compatibility before purchasing any aftermarket parts.
Maintaining Your Kel-Tec Sub 2000 Charging Handle
Proper maintenance is crucial for the long-term reliability of your Sub 2000.
- Regular Cleaning: Regularly clean and lubricate the charging handle mechanism, removing any dirt, debris, or fouling.
- Proper Storage: Store your firearm in a clean, dry environment to prevent rust and corrosion.
Conclusion
The Kel-Tec Sub 2000 charging handle is a key component of this versatile firearm. Understanding its operation, troubleshooting potential problems, and performing regular maintenance will ensure your Sub 2000 functions reliably for years to come.
