Finding parts for your Glenfield Model 20 can sometimes feel like searching for a needle in a haystack. This rifle, a rebranded Marlin 39A, boasts a loyal following thanks to its robust design and accuracy. But as with any firearm, parts eventually wear out or break. This guide will walk you through identifying Glenfield Model 20 parts, sourcing them, and performing basic maintenance.
Understanding Your Glenfield Model 20
Before diving into parts, let's establish a baseline understanding. The Glenfield Model 20 is essentially a Marlin 39A made by Glenfield, a subsidiary of Marlin Firearms. This means many parts are interchangeable. However, slight variations exist across production years, so precise identification is crucial.
Identifying Your Rifle's Specifics
To effectively source Glenfield Model 20 parts, you'll need to identify:
- Model Number: Confirm it's truly a Model 20, not a different Glenfield or Marlin variant.
- Serial Number: This helps determine the year of manufacture, influencing part compatibility. You can often find the serial number on the barrel or receiver.
- Barrel Length: Barrel length affects some part choices, particularly sights and stocks.
- Stock Type: Different stocks (e.g., Monte Carlo, standard) might require specific parts.
Common Glenfield Model 20 Parts and Their Functions
Glenfield Model 20 parts fall into several categories:
1. Action Parts
- Receiver: The main body of the rifle, housing the firing mechanism. Damage to the receiver is usually serious and requires professional repair.
- Bolt: The mechanism that cycles cartridges. A worn or damaged bolt can significantly impact functionality.
- Firing Pin: Strikes the cartridge primer, initiating the firing sequence. A broken firing pin means a non-functional rifle.
- Extractor: Removes spent cartridges from the chamber. A weak extractor can lead to malfunctions.
- Ejector: Forces the spent cartridge out of the rifle. Malfunctions here cause spent casings to remain in the chamber.
2. Stock and Forend
- Stock: The wooden or synthetic part of the rifle that the shooter rests against their shoulder. Cracked or broken stocks can be repaired or replaced.
- Forend: The wood or synthetic piece protecting the barrel. Like stocks, these can be damaged and require replacement.
- Buttplate: The rearmost part of the stock, protecting the shooter's shoulder. A worn buttplate can be replaced for comfort and preservation.
3. Barrel and Sights
- Barrel: The metal tube through which the bullet travels. Barrel damage is usually catastrophic.
- Rear Sight: A sight at the rear of the barrel that the shooter aligns with the front sight.
- Front Sight: Located at the muzzle end, the front sight aligns with the rear sight to determine point of aim.
4. Trigger Group
- Trigger: The mechanism that fires the rifle when pulled.
- Hammer: Strikes the firing pin.
- Sear: A safety mechanism that prevents accidental firing.
Sourcing Glenfield Model 20 Parts
Locating parts can be a challenge, given the rifle's age and the fact it was rebranded. Here are your best options:
- Numrich Gun Parts: This is a reputable source for many older firearm parts, including Marlin and Glenfield components.
- eBay and GunBroker: These online marketplaces often have individual sellers offering parts. Be cautious, though, and verify seller reputation.
- Gunsmiths: Experienced gunsmiths may have access to parts or know where to find them.
- Marlin Owners Forums: Online forums dedicated to Marlin rifles can connect you with others who may have parts or advice.
Maintaining Your Glenfield Model 20
Regular maintenance will extend the lifespan of your Glenfield Model 20 and prevent future part failures. This includes:
- Cleaning: Regularly clean the bore and action to remove fouling.
- Lubrication: Use a gun-specific lubricant to prevent wear and corrosion.
- Inspection: Periodically inspect the rifle for any signs of wear or damage.
Conclusion
Finding Glenfield Model 20 parts requires patience and research. By understanding your specific model, using reliable sources, and practicing diligent maintenance, you can keep your rifle in top shooting condition for years to come.
