Though a Kolar shotgun is arguably the most dependable and reliable firearm known to man, you should take proper maintenance precautions to ensure that it will function flawlessly. As with any type of firearm, residue can collect. Carbon, dirt, powder, dust, and even grease buildup can lead to gun malfunctions.
Luckily, these malfunctions can be avoided by keeping your shotgun properly cleaned, maintained and stored. Proper gun maintenance is a must for any responsible gun owner.
Storing Your Kolar
The gunsmiths at Kolar recommend that all Kolar shotguns be stored with the hammers dis-engaged. That being said, it is a good idea to release the hammers before you slip your Kolar into a gun sock or gun slip, or break it down into your hard case. To disengage the hammers, ensure that your firearm is unloaded and safe. Then, pull the trigger twice -once for each hammer. Some shooters prefer to use snap caps while dry-firing the gun; however, snap caps are not necessary for your Kolar shotgun. Dry-firing will not harm your Kolar shotgun in any way.
Cleaning Your Kolar
We recommend that you wipe down the exterior and interior of the barrel, the action and the receiver after each use. Rem Oil Wipes make this task quick and easy.
To remove dirt and to prevent rust after operating under rainy conditions, use a bore brush, such as the Comp-n-Choke Tornado Cleaning Brush, to clean the forcing cones (and the choke tube threads while you are at it). Then, run a Tico-tool or bore snake through the barrels to finish the job. Doing this will help to ensure your barrels stay strong and smooth.
Periodically, you should also remove and clean the trigger mechanism and the back-end of the receiver tang, which is only exposed with the stock removed.
When cleaning, you might find gun cleaning picks helpful for removing hard to reach carbon and powder build-up. Most gun cleaning picks are made of a high-strength polymer and will not scratch the surface of your gun.
It is also important to note that the trigger and receiver mechanism should be left dry. It is not recommended to leave standing oil or lubrication in the trigger or in the receiver. An air compressor or aerosol spray bottle both function well to remove any left-over oil that may persist after cleaning.
Greasing Your Kolar
In terms of grease, less is more. Excessive grease application can cause your Kolar shotgun to malfunction, especially if using grease that might thicken and/or freeze when used outside in cold temperatures. The gunsmiths at Kolar use Birchwood Casey RIG® gun grease. Over greasing or using relatively thick grease can cause residue to migrate into spaces that can hinder your shotgun from functioning properly.
It is recommended that you apply a rather thin layer of grease to the (1) trunnion cut-outs on each side of the barrel, (2) forearm locking mechanism on the barrel and (3) the forearm hinge surface. You should also periodically apply some grease to the locking bolt receptacles at the face of the barrel. Please see the below photos for guidance. Please keep in mind that old grease should be removed prior to applying new grease.
