Description

Sig Sauer, M400 TREAD, Semi-automatic, 223 Rem, 556NATO, 16″ Stainless Barrl, Magpul SL-5 Stock, M-Lok Handguard, Black Finish, 1 Mag, 30Rd.

It’s hard for most of us to look at the AR platform with the eyes of a new shooter, but I recall the time I laid eyes on a Colt catalog as I shopped for my first AR rifle.

I remember looking at a dense page of type that listed about 50 rifles, one per line, using an impenetrable shorthand for every spec and feature. The differences between models were stated as nothing more than a letter or number in a string of text; CL 14.5, 1/2-28, FSB, FH, CLG, H2.

In context, all those cryptic abbreviations make perfect sense now. But, years ago I had no idea what any of that meant. Further, if I wanted to pick up a new handguard or other accessory, I was still feeling around in the dark since I didn’t know what terms like, “delta ring compatible,” meant or what muzzle thread pattern I needed to order when adding a brake.

It’s with these wide eyes I look at the Sig Sauer Tread program and smile. There are a ton of ARs on the market, and on its face the M400 Tread is exactly that… just another budget-priced, factory AR built by a reputable manufacturer competing for space on very crowded gun store racks.

The Tread differs from its competitors in one, very important way that has nothing to do with the rifle itself. Along with the M400 Tread, Sig’s releasing a suite of OEM upgrade parts that remove all the mystery of compatibility from the AR upgrade process.

Choosing compatible parts for the Tread is as simple as finding the Gadsen yellow logo on the box of a Sig accessory. It makes the Lego concept that veteran AR owners take for granted and makes it accessible to the newb. To quote Sig’s EVP of Commercial Sales and Chief Marketing Officer Tom Taylor, “It’s like Garanimals for guns.”
