Initial Thoughts

The NBS Free Float M-LOK Handguard is an American Made handguard. It features a monolithic rail, and is machined from a 6061-T6 extrusion. The finish is type 3 hard coat anodizing.

The handguard is nice and slim, feels nice in hand. It fit nicely over my low profile gas block, and features 7 sides of versatile M-LOK attachment slots. The handguard also includes a barrel nut, and its non-indexing! It makes it easy to properly torque the nut and even easier to install the handguard over it.

Field Tests

After installing the NBS Free Float M-LOK Handguard, we took our AR-15 to the range. Handling with the 12″ handguard was good. The rail is slim enough to get a good grip on. Instead of blasting a few thousand rounds of ammo through the AR, we dealt with some reload issues. We discovered that our .223 reloads had slight deformations under the shoulder, causing bad chamberings and feeds. The handguard got a beating while we tried to chamber and extract the rounds.

After changing out ammo, we spent time shooting with the NBS Free Float M-LOK Handguard. It worked well, felt good, and never moved on us. Even after the abuse.

Critical Observations

We really couldn’t find any issues that we had with the NBS. Its manufactured well, has a nice finish, it did its job, did not move, and was more than we expected from a budget handguard.

Conclusion

The NBS Free Float M-LOK Handguard is a great value, backed by a lifetime warranty, Made in America, and uses a non-indexing barrel nut. It is equal or superior in quality to handguards that are 2 or 3 times the price. It looks great, and works with nearly any AR15 build budget. We’d recommend the NBS Free Float M-LOK Handguard for any AR build.
