Frequently Asked Questions

What AR platform rifles is this handguard compatible with?

The Reptilia 15" M-LOK handguard is designed to fit all M4 upper receivers. It mounts securely using the included barrel nut and comes with all necessary hardware for installation.

What does M-LOK mean, and what accessories can I mount?

M-LOK is a modular mounting standard that uses slots along the handguard. Any M-LOK-compatible accessory—tactical lights, foregrips, rail sections, sling mounts, and more—can be attached directly to the handguard without additional adapters.

Is the barrel nut included, or do I need to buy it separately?

The barrel nut and all installation hardware are included with the handguard, so you have everything needed to mount it to your upper receiver.

Why is this handguard made from 7075-T6 aluminum?

7075-T6 is one of the strongest aerospace-grade aluminum alloys available. Combined with MIL-STD hard anodize finish, it provides the rigidity needed for precision shooting and the durability to handle rough field conditions without flexing or wearing prematurely.
