Why Choose a Drop In Handguard
When it comes to drop-in handguards there are a few functions. The primary purpose is comfort and safety. They provide an excellent anchor point and improve your accuracy without conducting heat from the barrel. But handguards also can accommodate additional accessories for your AR-15. They can add Picatinny rails, M-LOK and KeyMod functionality.
The main benefit of a drop-in style handguard is that it is generally easier to put on and take off than the free-floating version. This means you can add the handguard without altering the existing AR-15 hardware.
Before you start picking the handguard that’s best for you, there are a few things to consider. Weight, heat resistance, and installation type are the first things to look at.
Adding too much weight to your AR-15 can tire out your arm and reduce the safety of the weapon. It can also impact the balance of the gun, so finding a lightweight grip is important.
Heat resistance will determine the effectiveness of the handguard–if you’re burning your hand after just a few shots… Yeah, not gonna work!
Also consider how the grip installs. This could mean making sure it fits your barrel length. But it also requires keeping mind how easy taking it on and off will be. You want something that balances ease-of-use with stability.
Once you’ve established the basic functionality and qualities of a handguard, you can start thinking about the bells and whistles. What sort of look are you going for? Does the handguard accommodate accessories, and if so what type of mounting system? Does it improve or take away from accuracy?
Drop-in vs Free-Floating Handguard
Why choose a drop-in handguard over a free-floating handguard? Convenience is the #1 reason, though people tend to fall on one side of the debate or the other. The main reason is that any gun with a delta ring and a front sight base is made to accommodate the drop-in. If you wanted to install a free-floating handguard you’d have to remove or shave down both of those parts.
Drop-ins also tend to be lightweight and inexpensive compared to free-float models.
That said, there are some advantages to free-float systems like less heat transference and better accuracy. But we’ll cover those another day.

- First and foremost, make sure it is unloaded! Remove the magazine and examine the chamber. Firearms safety should never be ignored.
- Gather your parts: your AR-15, your new handguard, the proper size hex key (often included with the handguard), an AR Combo Tool, and (if you have another handguard installed) a handguard removal tool.
- If you’re removing an older handguard, use your tool to pull back the delta ring and remove the old handguard.
- Take the new handguard apart using the Allen wrench if necessary, and separate the parts
- Insert the non-tapered end of the top piece to the area around the front-end cap. Then, use the handguard removal tool to insert the back end into the delta ring. Be sure to align the grooves in the barrel nut.
- Repeat with the bottom part of the handguard, making sure to line everything up.
- Use the supplied screws & hex key to fasten the handguard together.
- At this point the installation is complete, and you’re free to attach any additional rails or accessories.
