How To Reduce Your Ar-15 Weight

If you discover that your AR-15is heavy to handle, it is pertinent to find a way to cut the weight down to ensure you can use the rifle the way you wish. However, you are in luck as we will be giving tips on reducing the weight of your AR-15.

In the first instance, the barrel of the AR-15 is the part of the rifle that takes the most weight; hence, reducing the barrel’s weight will drastically cut down the weight of the AR-15. There are three different styles of reducing your barrel’s weight: reducing the barrel’s profile, fluting, and shortening.

Fluting involves the total change of your AR-15 profile and can be done by purchasing a better profile. Profile reduction is another awesome way of reducing your AR-15 weight and involves changing your profile to pencils. Lastly, shortening involves cutting down the length of the barrel to a shorter length. Shortening is the most recommended method.

It would be best if you also remembered to check out the Bolt Carrier Group, otherwise known as BCG of the rifle while attempting to reduce its weight. The BCG is another important part of the AR-15 and is critical to the adequate functioning of the rifle, although it also adds to its weight. However, you can reduce the weight of the BCG without causing any damage to your rifle.

Your AR-15 buttstock might also add weight to the rifle, and to reduce the impact of the buttstock, locate a nearby gun store and purchase a buttstock of about 5 ounces, depending on your choice to replace the existing one. It would help if you also considered getting a lighter rail alongside the buttstock to reduce the weight. However, you may find divergent rails attractive, making it difficult to choose one, although this will depend on your budget. We suggest a light rail of 0.7 ounces (0.32 kg) or less than this.

To cap it all, the last accessory you should also consider is the lighter optics will go a long way in reducing your AR-15 rifle weight. However, you should not just go for any optics but the most suitable one for your rifle. There are several optics with varying weights, such as 1.3 or 1.2 ounces, 0.08 pounds (0.03 kg), and so on. Out of this, we will recommend you purchase the lightest available lighter optics since the big ones might be too heavy for your rifle.
