Keeping your rifle clean is essential to keep it functioning properly. Before installing your BoAR Grip, consider cleaning your AR-15 to give it that new-gun feel.
Start by disassembling your rifle. It’s best to do this on a flat surface with a container to keep smaller parts in during the cleaning process. Make sure the firearm is unloaded and begin disassembling.
Next, you must separate the receivers. Release the upper and lower receivers by pressing the front and rear takedown pins from left to right. Bring the upper receiver up, pull the charging handle back while pressing it down, and remove the bolt carrier. Using the tip of the charging handle, depress the buffer retainer on the lower receiver and remove the spring and buffer.
Now that your rifle has been broken down into its major subassemblies, it’s time to strip the bolt carrier. Fully press the bolt rearward into the carrier and push the retaining pin with a small object until you can remove it with your fingers. Remove the firing pin. Rotate the cam pin 90 degrees and remove it from the bolt. Now you can remove the bolt from the carrier. Push the extractor pin out of the bolt using the firing pin. Your rifle is field-stripped and ready to be cleaned.
If you haven’t cleaned your rifle chamber recently, the interior probably has a greasy coat of black carbon residue. To keep your rifle in shape, it’s important you remove this residue. Unless you have an aerosol cleaner, you’ll have to get a little dirty. Using a powder solvent (CLP is also a nice option!) and a cloth or toothbrush, start scrubbing anything with carbon residue on it. Next, you must clean your Bolt Lug Recess Area. To properly clean this area you must have an AR chamber brush. This area can accumulate significant buildup, as it is where the lugs interface with the barrel extension. Using your brush and a cleaning solvent, scrub all debris off the lug recesses.
Now onto the bore. This part is a bit tricky and you may want to invest in some products to help you. You will need a cleaning rod, a way to keep the upper and lower separate, and bore solvent. Cleaning out the copper fouling build-up in the bore is very important and shouldn’t be neglected.
Once everything is cleaned, it’s time to inspect and lubricate. Make sure your parts aren’t cracked, bent, aligned, and sealed. Also, make sure you do a function test on your rifle so that you’ve confirmed it is operating properly. Now that you’ve ensured the integrity of your rifle, apply lube on every part that appears to have it’s finish rubbed down by friction. Don’t go easy on the lube, as these rifles need it in abundance!
If you’re not sure where the parts are or what part is which, there are plenty of guides to learning more about your rifle, including diagrams. Once your rifle is cleaned, reassembled, and you’ve done a proper function test, it’s time to slap your new BoAR grip on and get back to shooting!
