Description
Q built the Q-Sert handstop for folks who want a reliable, no-nonsense support hand reference without dropping serious cash on the machined aluminum version. It's molded from glass-filled nylon, which is the same tough material Magpul and plenty of others lean on for polymer grips, so it shrugs off range abuse while staying light. This is the black polymer 2-slot version, running about 4.5 inches long and tipping the scale at roughly 0.60 oz. That length gives your support hand a generous surface to index against and pull the rifle back into your shoulder pocket.
What the Q-Sert Handstop Does on Your Rifle
A handstop's whole job is repeatability. It gives your hand a consistent stopping point run after run, which keeps your grip and pressure the same shot to shot. Pull into it, drive the gun forward against a barricade, or just use it to keep your fingers clear of the muzzle. The generous girth on this one fills the hand nicely, so it works well whether you're running a long-range setup off a bipod or working through tighter, faster drills.
Why the Q-Sert System Is Different
Here's the thing to understand before you buy: this is not M-LOK or KeyMod compatible. Q-Sert is Q's own proprietary interface that skips the friction-and-locking-tab approach entirely. Instead, it uses stainless steel threaded inserts pressed into the handguard and a direct screw-in design, so accessories torque down onto steel for a repeatable, seriously strong lock-up. That means this handstop only fits Q-Sert equipped handguards found on rifles like The Fix, the MiniFix, and Q's AR-15 handguards.
Installation is about as simple as it gets. Line the handstop up with the Q-Sert slots, run the screw into the steel insert, and snug it down. No barrel nut removal, no hunting for tiny T-nuts, no fuss. If you're running a Q-Sert handguard and want an affordable way to lock your grip in place, this polymer version is tough to beat.

Frequently Asked Questions
Will the Q-Sert handstop fit my M-LOK or KeyMod handguard?
No, it will not. This handstop uses Q's proprietary Q-Sert interface, which relies on stainless steel threaded inserts rather than M-LOK or KeyMod slots. It only fits Q-Sert equipped handguards, such as those found on The Fix, the MiniFix, and Q's AR-15 handguards.
How is the polymer handstop different from the aluminum Q-Sert version?
Both share the same shape, size, and Q-Sert mounting, but this one is molded from glass-filled nylon instead of machined aluminum. That keeps the cost down significantly while still delivering a tough, functional handstop. The polymer version weighs about 0.60 oz, so it's genuinely light on your setup.
Is the Q-Sert handstop hard to install?
Not at all. You line it up with the Q-Sert slots on your handguard, thread the screw into the steel insert, and tighten it down. There's no barrel nut removal or fiddling with tiny T-nuts, so most people have it mounted in under a minute.
What is a handstop actually for?
A handstop gives your support hand a consistent reference point so your grip and pressure stay the same from one shot to the next. You can pull into it to load the rifle back into your shoulder, brace it against a barricade, or use it to keep your fingers safely behind the muzzle. It's a simple upgrade that pays off in better control and repeatability.
