Keeping Traditions Alive Since 1953

Sig built this kit to give M400 Tread owners a full toolbox of forend options in one box instead of buying pieces one at a time. It bolts onto any M-LOK rail interface, so while it was designed as the factory replacement for the Tread series, it plays nice with pretty much any AR-style handguard running M-LOK slots. Everything is molded from high-strength polymer in a matte black finish that matches the rest of the Tread family, and the whole kit tips the scale at only a couple of ounces so you are not adding real weight up front.
The idea here is options. You get a vertical grip for a traditional straight-down hold, a barricade stop for bracing against cover or a shooting bench, plus long and short handstops for folks who like an indexed, hand-forward position. There are also long and short M-LOK rail panel sections in the box, so you can fill open slots or build out a specific hand stop. Mix and match until the rifle feels right, then swap it around later if your setup changes.
Install is about as simple as M-LOK gets. The kit ships with the screws and T-nuts you need, so all you bring to the table is a hex key. Loosen, slot, tighten, done. Because you can reposition anything along the rail, there is a lot of room to fine-tune reach and grip angle without buying extra parts.
Shooters running short-barreled builds and pistol setups have found this kit especially handy since the compact handstops give you something solid to grab on a tight forend. Whether you are stabilizing off a barricade, keeping your hand off a hot handguard after a few mags, or just want a cleaner index point, this one covers a lot of ground for one purchase.
Yes. It was designed as the factory kit for the M400 Tread, but since every piece attaches through the M-LOK interface, it works on any handguard with M-LOK slots. That includes most AR-15 style rifles and pistols running M-LOK rails.
No. Everything mounts with the included screws and M-LOK T-nuts, and all you need on your end is a hex key. It is a quick, tool-friendly setup that most folks can knock out at the bench in a few minutes.
The whole idea is flexibility. Instead of guessing which grip style suits you, you get a vertical grip, a barricade stop, and both long and short handstops so you can test different holds and reposition them anywhere on the rail. It saves you from buying accessories one at a time to find what feels right.
It works well for compact setups. The shorter handstops give you a solid index point on a tight forend where a full vertical grip might feel cramped, which owners of short-barrel and pistol builds have appreciated.
