How To Clean Bolt Carrier Group

Equally reliable as the AR15 platform is, every gun needs cleaning now and and then. Even though a properly build AR-15 tin become thousands of rounds without cleaning reliably (I've done it), a clean rifle will always be more reliable than a muddied ane once lube starts to burn off. Most chiefly, how can yous flex your  expensive bolt-carriers logo, if it'due south too muddy to exist seen? So let's intermission downwards cleaning your BCG, from start to finish.

Disassemble Your Rifle

Safety Beginning

Please, PLEASE, earlier all else, make certain y'all're being condom. We've all heard of the accidents that happen when someone doesn't properly clear their weapon earlier cleaning information technology.

Before anything, make sure the rifle is e'er pointed in a safe direction. Secondly, drop the magazine. Finally, clear the chamber by cycling the bolt with the charging handle and visually verify that the chamber is clear.

I am somewhat neurotic and will cycle the bolt multiple times, fifty-fifty though I know the weapon is clear. If I prepare down a weapon fifty-fifty for a second, I'll re-clear it earlier I go back to cleaning or dry-fire or whatever I was doing. It's better to be overly cautious, than to accept not been cautious enough. Go along a perfect prophylactic record.

Disassembly

Thankfully the AR-xv is a simple rifle, and field-stripping it takes all of ten seconds.

First, make sure the bolt is forward, so the upper and lower receivers can separate.

Second, push out the rear takedown pin.

Third, pull out the entire bolt-carrier with the charging handle.

Cleaning Your Bolt-Carrier (BCG)

This looks pretty dirty, merely it'due south simply a few hundred rounds.

Disassembly of a BCG

First, remove the firing pin retaining pivot which is located on the side of the bolt carrier that does not have the forward assistance serrations. This can be done using a pair of needle-olfactory organ pliers, a selection, a pen, the tip of a bullet, or other tools capable of gripping the pocket-size pin.

After removing the retaining pin, the firing pin should easily slide out. If there is carbon build up that prevents the firing pin from sliding out (like there was on mine), you can easily remove it by tapping the commodities carrier on to the table or using your finger to pry it out.

The side by side disassembly pace includes removing the cam pivot. This pin is located underneath the gas central and fits into the bolt. In club to remove this pivot, you will demand to brand certain the bolt is pushed inward. You volition and then demand to rotate the cam pivot nearly ninety degrees then that the rectangular caput of the pin is parallel with the commodities carrier. After rotating the pin, you will be able to pull it out. After removing the cam pin, the commodities volition hands slide out.

Cleaning a BCG

To prepare upward your BCG cleaning workspace it is helpful to lay downward plastic, such as a piece of plastic wrap, or a small garbage purse. This makes clean-upwards quick and like shooting fish in a barrel.

The best fashion to brainstorm cleaning your bolt carrier grouping is to rub a small layer of CLP or other type of gun cleaning solvent on each of the BCG parts. If you accept a meaning amount of carbon build-up, it will be helpful to permit the CLP sit on each of the parts for a few minutes.

After allowing fourth dimension for the cleaning solvent to break down the carbon, y'all will demand to piece of work on some of the difficult to reach locations. Cotton fiber swabs are bang-up for helping yous clean the inside of the bolt carrier also as on the bolt. Dip your cotton swabs in the cleaning solvent while wiping the areas with more carbon build up.

After cleaning the smaller areas of your BCG, make certain to rub down each part, including the firing pin, retaining pin, and cam pivot to remove whatsoever remaining carbon build upwards. Y'all tin do this with an old toothbrush, cotton patches, or cutting upward pieces of an old t-shirt. Once you have removed all the carbon, do a final wipe down of each part with a clean cloth or sometime t-shirt.

Lubricating Your BCG

Before reassembling your BCG, y'all need to oil each function. Having a properly oiled bolt carrier group will help your AR-fifteen run more efficiently. The general rule of oiling is to place oil in any location where there volition exist metal on metallic contact. You tin can employ a little CLP or whatever specialized firearm lubricant. I personally prefer an oil with a needle tip applicator which makes information technology easy to apply in areas that are more difficult to accomplish.

After lubricating each office, your BCG is fix for reassembly and another day out on the range.
