Top 3 Best Quad Rail for Ruger AR 556

[content-egg-block template=custom/all_offers_list groups =”t1,t2,t3″]

Types of Quad Rails

The three types of Quad Rails are Picatinny (also known as MIL-STD-1913 Rail), Keymod, and M-LOK. The quad rails lined up vertically along the top, back, and sides of a rifle or shotgun to add sights for aiming, lights for low light shooting situations (such as night hunting), and grips for recoil control.

Picatinny

The Picatinny rail system is the most popular type of rail. It utilizes slots or grooves spaced at uniform intervals to allow accessories, such as sights or flashlights, to be mounted perpendicular to the gun’s barrel. This allows for a large selection of accessories and easy removal without having to remove the rail itself.

Keymod

A newer type of mounting system for firearms, Keymod is more modular than Picatinny rails because it uses a series of keyhole slots instead of one large slot. You can mount an accessory on several different elevated surfaces within a particular location.

M-LOK

It is a mounting system for firearms that uses small holes drilled into the rails, which allow accessories to be attached or detached without removing any rail sections. It allows shooters to customize their firearms with attachments such as grips and lights without disrupting shooting consistency.

What To Consider While Buying The Best Quad Rail for Ruger AR 556?

When purchasing a new Quad rail for your Ruger AR 556, there are many things that you should keep in mind before you buy it from any store. The following article will give you an in-depth look at what factors need to be considered before purchasing.

Less Weight

First of all, you should consider the weight of the rail. The lack of a quad rail can considerably bring down the overall weight of your Ruger AR-556, so it would be best to buy one if you plan to use it for competitive purposes. It is always better to save as much weight as possible if you participate in a shooting competition.

Quality of Material

Secondly, you should make sure that the rail is made out of high-quality material so you won’t have to worry about breaking it while you are using it. A low-quality quad rail can break down after extended use.

It can also wear off easily and leave you with no way of replacing it if anything goes wrong, which would inconvenience your shooting experience and affect your performance on the field. You should always choose only those products made from solid steel or aluminum because they have been proven to last longer than other materials for years.

Design

The rail must be designed specifically for your Ruger AR 556 model, or it might not fit into your gun. Many shops don’t state which models they have parts for, so you should always ensure by measuring them with those from the manufacturer and asking them if their components will fit your Ruger AR 556 rifle before buying anything from their store.  You should also check out the product’s ergonomics because a poorly designed quad rail can be more work to use than one that has been well thought out for your specific firearm.

Price

You should also consider the price of the quad rail before buying, which gives you a lot of options to choose from, depending on your budget. If you want only the best quality products available on the market today, then go for the pricier ones made from solid steel or aluminum. Still, if you just need something decent and simple, then cheaper models will do.

Helps with Accuracy

Lastly, you must consider the level of accuracy that each quad rail can offer because this will give you an idea of how well your Ruger AR 556 will perform without any trouble in competitions. Most drills require extreme precision when aiming, so make sure that your barrel includes a quad rail in case there are going to be many shots taken during the game.
