Description
The Die Free Co Full Stop is one of those simple parts that earns its spot on a rifle fast. It bolts to any M-LOK handguard and gives you a rear index point for your support hand, a finger stop to keep your grip consistent shot to shot, and a hard edge to load against a barricade or door frame. The gray version wears a clear Type III hardcoat anodize, so you get that silvery natural-aluminum look that pairs nicely with FDE, gray, or two-tone builds.
What the Full Stop Brings to Your M-LOK Rail
Die Free Co machines this one from 6061-T651 aluminum and keeps it small on purpose. It measures about 1.3 inches long, 0.6 wide, and 1.36 tall, and tips the scale at roughly 0.8 ounces, so it adds control without adding bulk or weight. The compact footprint means it plays well alongside a light, laser, or vertical grip without crowding the rail. The textured face gives your hand something to bite into whether you are running it as a straight hand stop or leaning into cover.
Getting the Full Stop Dialed In
Installation is quick and repeatable. Die Free Co recommends biasing the Full Stop toward the rear of the firearm so the M-LOK rear recoil lug seats against the slot, which keeps it from creeping under recoil. Use a 3/32 Allen bit and torque the hardware to 25 in-lbs, with 35 in-lbs as the ceiling, and a dab of blue Loctite is a smart call for anything you want to trust hard. From there it just stays put.
Die Free Co is a small New Hampshire outfit built by folks who came up in the firearms world, and this Made-in-USA piece reflects that no-nonsense approach. If you want one accessory that covers a hand stop, finger stop, and barricade stop in a clean gray finish, the Full Stop is an easy pick.

Frequently Asked Questions
What rifles does the Full Stop fit?
The Full Stop mounts to any handguard with M-LOK slots, which covers most modern AR-15, AR-10, and similar rifles running M-LOK rails. It bolts on directly with the included hardware, so no adapter is needed. Just make sure you have an open M-LOK slot where you want your index point.
How do you install the DFCO Full Stop so it doesn't move?
Bias the Full Stop toward the rear of the firearm so the M-LOK rear recoil lug seats into the slot, then torque the hardware to 25 in-lbs with a 3/32 Allen bit, staying under the 35 in-lb max. A drop of blue Loctite on the screws helps it hold up to repeated use and recoil. Once it's seated and torqued, it stays locked in place.
Is the Full Stop really a hand stop, finger stop, and barricade stop in one?
Yes, the design pulls all three jobs. It works as a rear hand stop for support-hand indexing, a finger stop for a consistent grip, and a hard edge to load against barricades or cover. How you use it is up to you and your shooting style.
What does the gray finish actually look like?
The gray Full Stop uses a clear Type III hardcoat anodize, which gives 6061 aluminum that natural silvery-gray look rather than a dyed color. Keep in mind anodize shade can vary slightly from part to part, which is normal for this kind of finish. It pairs well with gray, FDE, and two-tone builds.
