Remington Model 1100 Disassembly: A Step-by-Step Field Strip Guide for Owners and Technicians
The Remington Model 1100 remains one of the most successful shotguns ever produced, and understanding its disassembly process is essential for safe maintenance, troubleshooting, and repair. This article provides a detailed, objective walkthrough of how to properly field strip and partially disassemble the Model 1100, emphasizing critical safety steps and manufacturer recommendations. By following these procedures methodically, owners and technicians can maintain reliability while avoiding damage to components or injury.
Safety is the first principle of any firearm maintenance procedure, and it begins before the weapon is even handled. The fundamental rule is to treat every firearm as if it is loaded until you have personally verified, through a safe and consistent routine, that it is not. With the Remington Model 1100, a smoothbore shotgun designed for reliability and ease of use, correct disassembly for cleaning and maintenance follows a logical sequence that prioritizes the ejection of ammunition and the confirmation of an empty chamber. This guide explains the standard field strip and basic disassembly steps, drawing on the design intent and specifications common to the Model 1100 platform.
The primary objective of disassembly, particularly for routine cleaning, is to access the action, barrel, and internal components without compromising the integrity of the shotgun. For the Model 1100, this process is intended to be straightforward, allowing a competent user to remove the barrel, separate the receiver, and clean or inspect the bolt and carrier system. However, complete "takedown" to the level of individual trigger or carrier parts is typically unnecessary for standard maintenance and should only be performed by qualified gunsmiths to ensure proper reassembly and safety. The following steps reflect the standard procedure recommended for field-level maintenance.
Before beginning any disassembly, ensure the shotgun is completely unloaded and safe. Remove the magazine tub by pressing the release button or rotating the designated lever, depending on the model year and specific variant. Visually inspect the chamber and magazine well to confirm they are empty, then physically verify by running a finger or a cleaning rod through the chamber. Only when you are certain there is no ammunition present should you proceed to the next stage of handling.
The initial step in accessing the internal components involves separating the barrel from the receiver. Begin by locking the action open by pulling the forend rearward and engaging the tang safety, if so equipped, or by holding it in the open position. With the muzzle pointed in a safe direction, grasp the forend and move it forward. On most Model 1100 configurations, the forend travels along the magazine tube and will clear the action, revealing the barrel nut or pivot pin located at the front of the receiver.
Once the forend is removed, attention turns to the barrel attachment. On many models, a barrel nut or locking ring secures the barrel to the receiver. Using the appropriate wrench or specialized tool provided with the shotgun, carefully loosen this nut in the direction specified by the manufacturer, which is typically counterclockwise. Apply steady, even pressure and avoid using excessive force, as components can be damaged if leverage is applied incorrectly. If the barrel is secured by a pivot pin rather than a nut, the procedure will involve carefully tapping the pin's retainer pin to release the barrel for removal.
With the barrel nut loosened or the pivot pin released, the barrel can be carefully pulled forward and away from the receiver. On the Model 1100, the recoil spring is typically housed within the buttplate or the rear of the stock, so this component will remain attached to the receiver assembly. As the barrel is extracted, take note of how the recoil spring and associated components are arranged, as this layout must be replicated exactly during reassembly to ensure proper function. Laying these parts out in the order they were removed is a best practice that prevents confusion later.
The receiver is now exposed, allowing for inspection of the action bars, bolt, and internal surfaces. To remove the bolt assembly, locate the bolt lock or retention mechanism, which may be a button, lever, or set screw depending on the exact model and year of manufacture. Engage the safety and depress or rotate the bolt lock to release the bolt, then carefully retract the bolt and its associated carrier from the receiver. This exposes the main spring and plunger, which are housed in the bolt face or carrier channel. Note the orientation of the main spring, as it is often specifically designed to fit in one direction to maintain correct compression.
When disassembling any internal components, it is crucial to keep track of small parts and springs. These components are under tension and can be hazardous if they are released unexpectedly or lost. Using a clean, organized workspace with a tray or mat can prevent the loss of small pins, springs, and detents. Never use excessive force when removing parts; if a component feels stuck, double-check for hidden retaining pins or the correct release mechanism before proceeding.
Documentation and reference materials are valuable assets during disassembly and reassembly. The owner's manual specific to your Model 1100 variant provides model-specific instructions, torque specifications (where applicable), and diagrams that illustrate the proper sequence. Photographs taken during disassembly can serve as a visual guide when putting the shotgun back together. If the manual is not available, contacting Remington customer support or consulting verified online resources for the Model 1100 platform can provide clarification on specific steps.
Reassembly is essentially the reverse of the disassembly process, but it requires the same level of care and attention to detail. Each component must be returned to its correct position and orientation, with springs properly seated and retention mechanisms secured. Before final assembly, it is good practice to inspect all parts for wear, damage, or excessive carbon buildup, replacing any components that are compromised. Once the shotgun is reassembled, a function check should be performed without chambering ammunition to verify that the action cycles smoothly and that all controls operate as intended.
While the field strip and basic disassembly are suitable for routine cleaning, more extensive work such as removing the trigger group, replacing internal springs, or working on the firing pin safety should be left to qualified professionals. Improper reassembly of critical components can lead to malfunctions or safety hazards. For most owners, sticking to the barrel, forend, bolt, and action bar cleaning provides ample maintenance capability without venturing into complex gunsmithing.
Regular and correct disassembly and maintenance significantly extend the service life and reliability of the Remington Model 1100. By following the manufacturer's guidelines and prioritizing safety at every step, owners ensure their shotgun remains a dependable tool for years to come. Understanding the sequence and reasoning behind each step transforms maintenance from a chore into a fundamental aspect of responsible firearm ownership, reinforcing the relationship between the operator and the equipment.
