Airsoft Rifle Product Details

King Arms Colt M4A1 FPS-450 AEG Electric Airsoft Rifle

Airsoft Rifle Product Features

Electric Airsoft Rifles use batteries as their power source and they shoot very fast. Some Electric Airsoft Rifles come with semi-automatic fire. That means that when you pull the trigger only 1 BB will come out at a time. Other Electric Airsoft Rifles come with full-automatic fire. This means that when you pull the trigger multiple BBs will come out at a time. The longer you hold the trigger down the more BBs come out. Check the description above to see which kind of gun this is and if it is right for you. Electric Airsoft Rifles don’t require any pumping or cocking, just simply point and shoot. This is a High End Electric Airsoft Gun. Please only use .20 gram high quality BBs with this item in order to keep it in proper working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. Also, to keep your Electric Airsoft Gun working properly, do not fire the gun when there are no BBs in it as it may cause damage to your gun. You must be 18 years of age or older to purchase this Airsoft gun.

Airsoft Rifle Tactics

Airsoft rifles are very effective weapons. They can shoot over 140+ feet. Airsoft rifles like the gun have broad applications on the airsoft field from close range skirmishes (keep in mind the safest minimum engagement distances and guidelines) in addition to long-range engagements. For CQB, hold the rifle in such a way where you can quickly aim and shoot at targets. This consists of using the rifle’s stock to bear the airsoft weapon in addition to holding the rifle at angles away from your cover.

An additional method to shoot this brand rifle in close-range environments is to secure the stock (or rear of the weapon) between your bicep and body to shorten the overall length of the airsoft weapon in front of you. This technique is practical to keep the weapon closer to your body when using the gun in areas which allow players to shoot airsoft rifles in enclosed areas for room to room clearing and close quarters combat.

When shooting the King Arms Colt M4A1 FPS-450 AEG Electric Airsoft Rifle rifle at long ranges, shoulder the weapon’s buttstock for a firm and stable shooting stance. This will provide the very best precision for shooting airsoft BBs over longer distances at 100+ feet.
