The Kel-Tec Sub 2000 is a popular pistol-caliber carbine known for its unique folding design and affordability. One frequently asked question revolves around its barrel threading. This guide provides a comprehensive overview of the Kel-Tec Sub 2000 barrel thread specifications, compatibility, and considerations for modification.
Understanding Kel-Tec Sub 2000 Barrel Threading
The Kel-Tec Sub 2000's barrel threading isn't standardized across all models or years of production. This lack of consistency is a crucial point to understand before considering any modifications. Some models feature threaded barrels, while others do not. Therefore, determining whether your specific Sub 2000 has a threaded barrel is the first step.
Identifying Your Barrel's Threading
The simplest way to determine if your barrel is threaded is by visually inspecting the end. A threaded barrel will have clearly visible threads at the muzzle. If you're unsure, carefully examine the area. Do not attempt to force anything onto the barrel if you cannot visually confirm threading. Improperly forcing a suppressor or other attachments can cause damage to your firearm.
Thread Pitch Variations
Even among threaded models, the thread pitch can vary. While the most common thread pitch for the Kel-Tec Sub 2000 is 1/2x28, it's essential to verify this with your specific firearm's manual or through the manufacturer. Using the wrong thread pitch can result in damage to your firearm and is potentially dangerous.
Compatibility and Modifications
Once you've confirmed your Sub 2000 has a threaded barrel and determined the thread pitch, you can explore various accessories.
Suppressors
One of the most popular reasons for a threaded barrel is suppressor compatibility. Many suppressors are available for pistol-caliber firearms, offering sound reduction and recoil mitigation. Remember to always ensure any suppressor you choose is compliant with local and federal regulations.
Flash Hiders and Compensators
Beyond suppressors, threaded barrels also allow for the attachment of flash hiders and compensators. These accessories can help reduce muzzle flash and recoil, enhancing both the shooter's comfort and accuracy.
Other Attachments
Other accessories compatible with a threaded barrel include muzzle brakes and thread protectors. A thread protector is highly recommended when not using a suppressor or other muzzle device to prevent damage to the barrel threads.
Considerations Before Modification
Before modifying your Kel-Tec Sub 2000, consider the following:
- Legality: Always check your local and federal laws regarding firearm modifications. Some modifications may be restricted or prohibited.
- Warranty: Modifying your firearm may void the manufacturer's warranty. Review your warranty terms before making any changes.
- Safety: Improper modifications can be dangerous. If you are not comfortable performing these modifications yourself, seek assistance from a qualified gunsmith.
Conclusion
The presence of barrel threading on a Kel-Tec Sub 2000 significantly expands its customization options. However, careful attention to detail is crucial. Always verify your barrel's threading and thread pitch before purchasing any accessories. Prioritize safety and legality throughout the process. Consult with a qualified gunsmith if you're unsure about any aspect of modification.
