The Q-SERT Accessory Rail – 4.5" is built for shooters who demand more than off-the-shelf. Machined from lightweight, durable aluminum and finished to survive abuse, this rail locks into your Q-SERT handguard with zero drama.

Perfect for mounting bipods, grips, lights, or whatever else you need to finish the fight (or the hunt), the 4.5" size strikes the balance between compact and capable. Installation is stupid simple, rock solid, and keeps your rifle sleek without unnecessary bulk.

When you run Q-SERT, you’re running lighter, cleaner, and stronger. This isn’t M-LOK with a new sticker—it’s Q’s take on doing rails right.
