Cleaning a semi-automatic shotgun isn't just about keeping it looking sharp. If you own a Remington 1100, regular strip-down and maintenance prevent carbon fouling from causing stubborn feeding jams. You don't need a gunsmithing degree to clean your receiver, magazine tube, and gas system, but you do need patience, the right tools, and an orderly workspace. Let's walk through the complete teardown process safely and efficiently.
Before you touch a single pin or screw, verify the chamber and magazine tube are completely empty. Point the muzzle in a safe direction, pull the charging handle back, lock the bolt to the rear, and visually inspect the chamber. Drop the bolt home only after you're certain no rounds remain. Remove any tactical slings, shell carriers, or slip-on recoil pads so they don't get in your way. Grab a flathead screwdriver, a brass punch set, a nylon cleaning brush, gun oil, and a clean workbench lined with an old towel or silicone mat.
Removing the Barrel and Fore-End
The first milestone in field-stripping your shotgun is separating the barrel from the receiver and stock assembly. This exposes the gas system and magazine tube, which accumulate the heaviest carbon buildup during a day at the clay pigeon range or duck blind.
Unscrew the magazine cap located at the very front of the fore-end wood. Pay attention as you twist it off. Some configurations feature a detent ball and spring inside the cap, so don't let it pop out and roll under your workbench. Once the cap is free, slide the metal or synthetic fore-end forward and off the magazine tube. Set these parts aside safely.
Grab the barrel by the rib or near the muzzle, pull firmly forward, and slide it out of the receiver ring. The barrel extension and gas piston rings will clear the magazine tube easily. If it feels stuck, check that the bolt isn't locked forward in an awkward position or that you didn't leave a magazine plug retainer clipping anything inside. You now have the barrel isolated for separate cleaning.
Teardown of the Gas System
The gas-operated system is what makes the Remington 1100 cycle shells reliably, but it's also where carbon bakes on thickest. If you neglect this area, your gas ports will clog, leading to short-stroking and failure-to-feed issues.
Slide the piston seal off the magazine tube. Behind it, you'll find the piston rings seated on the gas cylinder collar welded to the barrel. Inspect these piston rings for cracks or excessive wear. They should fit snugly around the magazine tube without binding. Wipe down the magazine tube with a solvent-dampened cloth to remove burned powder residue and plastic fouling left behind by wad travel. Avoid scraping the steel with hard metal tools, as deep scratches can disrupt the smooth travel of your action sleeves.
Removing the Trigger Assembly
Getting inside the receiver requires dropping the trigger group. This is where many first-time owners make mistakes by trying to force pins out the wrong way or losing small internal tension springs.
Locate the single trigger plate pin passing horizontally through the rear bottom of the receiver. Use a brass punch and a small hammer to tap this pin out from either side. Once the pin is clear, push forward slightly on the trigger guard and swing the entire trigger assembly down and out of the receiver housing.
Don't panic if the carrier dog or shell latch shifts slightly. The trigger plate houses the hammer, sear, and disconnector mechanism as a single modular unit. Set it down on your mat and resist the urge to strip the trigger components down any further unless you're replacing a broken spring. Deep internal trigger work requires specialized jigs and isn't necessary for routine deep cleaning.
Extracting the Bolt and Operating Handle
With the trigger assembly out of the way, you can slide out the internal bolt components. This step requires freeing the operating handle and carrier assembly from the receiver channels.
Pull the charging handle straight out to the right side of the bolt. It's held in place by friction and a detent ball, so a firm, steady tug will release it. Reach into the receiver, push the bolt slightly forward to clear the internal rails, and slide the bolt assembly forward out through the front of the receiver.
Next, detach the action bar sleeve from the bolt. The action bars run parallel alongside the magazine tube when the gun is fully assembled, transmitting the gas pressure rearward to cycle the bolt. Inspect the weld points on the action bars for cracks or fatigue. This is a high-stress area, especially if you shoot heavy magnum waterfowl loads regularly. You can reference specific parts diagrams and safety bulletins via the Remington Official Site.
Cleaning, Lubrication, and Inspection
Now that your shotgun is fully disassembled into its core modules, inspect every component for wear and tear. Look closely at the recoil spring housed inside the wooden stock, which you can access by removing the buttpad and unscrewing the stock bolt with a long flathead screwdriver or socket extension. If that tube is packed with grit and old grease, wash it out with aerosol gun scrubber and apply a very light coat of synthetic oil.
Apply a quality solvent to the barrel bore, letting it sit for a few minutes to break down plastic residue and copper fouling. Run a bronze brush through the chamber and bore from breech to muzzle, then follow up with clean patches until they emerge white. For more detailed technical specifications on firearm mechanics, you can consult resources hosted by the Bureau of Alcohol, Tobacco, Firearms and Explosives.
When lubricating, remember that less is often more. Excess oil attracts unburned powder, dirt, and field debris, turning into an abrasive paste that accelerates wear. Apply a thin film of oil to the magazine tube, the outside of the bolt, and the sliding contact points inside the receiver rails. Wipe away any pooling droplets before reassembly.
Reassembly Sequence
Putting everything back together requires the reverse of your teardown steps, but sequence matters to avoid jamming parts together incorrectly.
- Slide the action bar sleeve back onto the magazine tube and align it with the bolt assembly inside the receiver.
- Push the bolt assembly rearward into its operating tracks until it seats correctly against the internal action springs.
- Reinsert the charging handle into the bolt slot, pressing firmly until you feel it click into its internal detent.
- Position the trigger plate assembly back into the bottom of the receiver, hooking the front into the receiver recess first, then swinging it upward.
- Tap the trigger plate pin back through the receiver holes using your brass punch.
- Slide the barrel back onto the receiver, ensuring the gas cylinder ring seats properly over the magazine tube and piston seals.
- Slide the fore-end wood back into place over the barrel and magazine tube.
- Screw the magazine cap back onto the front of the magazine tube hand-tight, making sure the detent engages securely.
Once reassembled, perform a safety check. Clear the chamber, verify the safety button works correctly, and cycle a couple of dummy snap caps through the action to confirm smooth feeding and extraction.

Frequently Asked Questions
How often should I perform a complete breakdown of my Remington 1100?
You should conduct a thorough disassembly and deep clean every five hundred rounds, or immediately after hunting in wet, muddy, or sandy environments. Routine surface wiping after every range trip is usually sufficient for normal operation.
Why won't my bolt lock back after the final shot?
This usually happens because carbon buildup is restricting the travel of the gas piston rings or the magazine tube is too fouled to let the action bars move rearward freely. Clean the gas system thoroughly and ensure you haven't over-lubricated the magazine tube.
Can I interchange barrels between different 1100 gauges?
No, 1100 receivers and magazines are caliber- and gauge-specific. You cannot mount a 12-gauge barrel onto a 20-gauge receiver, and vice versa, due to major dimensional differences in the frame and bolt face.
What causes light primer strikes during shooting?
Light primer strikes often stem from hardened oil or dirt trapped inside the trigger group or the bolt assembly around the firing pin. Strip the bolt and trigger group, clean out old gunk, and ensure the firing pin moves freely back and forth without binding.
