Could someone help me out and give me a brief explanation or point me to a resource on how to break in your brand new AR-15. How does the cleaning work when you take it to the range for the first time? Thanks Alot. Justice_Keeper |

Cleaning: The first thing you want to do is to go and buy some CLP. The easiest way is to just buy a large Can of BreakfreeCLP $7.95. A quick rundown of cleaning/removing the grease. 1. Pull the carrier and bolt. Pull the take firing pin retainer, then firing pin, then turn the bolt cam 90* with the bolt all the way back and remove the cam, then pull the bolt straight out. Wet these parts down, then wipe off the CLP/grease, then give them a quick shot of CLP and re-assemble. 2. Give the inside of the upper, the inside of the barrel, and extension a shot of CLP. Then give the Gas tube(inner) a shot of CLP. Let the barrel/gas tube soak for a few minutes, then run a brass brush down the barrel a few times. This will help the CLP remove the grease, but even better, it will remove the burs from the gas port opening in the barrel. Wipe down the inside of the upper, then use the chamber brush and give the chamber/barrel extension a few strokes. Now use a Q-tip and clean the barrel face and barrel extension lugs. The last thing to do on the barrel is run a few clean patches down the camber and barrel. Note: Always remember to run the rod from chamber to muzzle. Never push a rod from the muzzle, or you may damage the crown. The last thing that gets over looked is the buffer and tube. Start by pressing the buffer retaining pin down and allowing the buffer to walk past the pin. There is a second lip on the buffer that will require you to either turn the buffer to one of it's flat spots, or you can us a pick and press the retainer a second time to allow the buffer to fully walk out of the tube. Give the buffer, tube, and spring, a shot of CLP and let it sit for a minute or two. Then wipe off the CLP/grease on the parts. Lube(CLP or Grease) the parts and re-insert. I should note that regarding the buffer tube/spring/buffer, some only use CLP to lube the parts while others use a light grease. Both ways are fine, but if you prefer to lessen the prong sound made by the buffer, the light grease will do the trick. The other part to clean is the barrel, which requires you to remove the hand guards. This is done only to remove any grease and is then lightly oil to prevent the barrel from rusting. If you skip this step, the barrel will smoke a bit while the grease is being burnt off the barrel. The clp will smoke also, but will not baked on like the grease. Breaking in the rifle: Depending on the barrel: If the barrel is chromed lined, then just shoot the rifle. Take your time and don't allow the barrel to over heat and you will be fine. It the barrel is a production non-chromed barrel, then again, take your time shooting and clean the barrel once your done. If you prefer, you could Fire Lap the barrel, but this will be mute if you plan using the rifle for anything other than target/match shooting. The first time you go buck wild and start to over heat the barrel, you have just wasted your time Fire lapping the barrel. If it is a Match barrel that has not been Lapped, Then check with the barrel manufacture. Note: Lapping, either hand or firing, is done to unify the rifling. The reson for keeping the barrel clean is to allow the bullet/slug to polish the rifling edges consistently. On a fouled spot, the rifling edge is not polished. The last and most important thing to do on your new rifle during the first outing is to run the bolt and carrier wet with CLP. The upper/carrier/barrel extension will be little rough and will need to mate with each other. After a few hundred rounds, you can cut back on the CLP used to keep the rifle running. Hope this helps. |
