Airsoft Gun BB Mechanics

Did you know that the weight and quality of your chosen 6mm airsoft ammunition can play a huge role in how long your new airsoft gun lasts?

Cheap airsoft bb's are a good thing, Cheaply made airsoft bb's are not. Let me explain...

Todays stock airsoft guns are shooting hotter than ever and many airsoft manufacturers now feature brand new Airsoft Electric Guns known as AEG's that are shooting 350 FPS plus out of the box. For instance the newest line of AGM full metal airsoft clones are shooting 380 FPS with .20 gram bb's out of the box with no upgrades installed. If I use lighter .12 gram bb's in one of these guns my FPS will jump to 450 plus which is to high for most official airsoft fields in the USA. Most fields designate any gun that chronographs over 400FPS as a sniper weapon and strict rules of engagement are levied on the player. 6MM .12 gram bb's are not as dense as the heavier .20, .23, .25 and higher weight bb's and do shatter often in the barrel causing dangerous shards of bb's to be propelled at your target. Besides the obvious safety issue this causes it will also create excessive jamming that will lead quickly to expensive repairs.

Airsoft BB Rule Of Thumb: If your gun shoots faster than 300FPS then only use .20 gram or heavier bb's.
The other big difference between cheap airsoft ammunition and precision grade airsoft ammunition will be the hardness of the material used to make the bb's. If you squeeze a bb with a pair of pliers it should flatten, deform and finally crack on the edges when enough pressure has been applied. If the bb shatters it is too hard of material and can shatter in the gun as explained above. Also of concern is the quality control parameters held for the Diameter of the bb's. Today's airsoft guns feature precision tight bore barrels that can only handle micro variations of size before big problems set in. Proper barrel cleaning procedures are a must and are shown in the picture to the right. Excessive jamming, broken air nozzles and broken tappet plates are almost always caused by jammed bb's. Jammed bb's can be attributed to a dirty barrel, a faulty hop up bucking or irregular airsoft ammunition. If you are having allot of mechanical and repair issues with your airsoft gun and you are properly cleaning the barrel after use and are not having hop up problems, then you may want to examine your current bb's or try using a new brand of bb to see if this helps alleviate problems. Airsoft gun repairs can be both frustrating and expensive even if you DIY so be sure you are using high grade precision bb's as this is the first step to good airsoft preventative maintenance.
