SIG Sauer Introduces the New SIG TREAD Snakebite SE

The two primary improvements that have been made to the Snakebite SE are its new Hybrid Compensator/Flash Hider and 2-stage match trigger. The SIG Snakebite SE will also feature an enhanced 13-inch free-floating M-LOK handguard. The unite flash hider/compensator combo offers the shooter minimal flash for low light shooting and reduced muzzle rise.

Meanwhile, the two-stage Matchlite trigger gives you an ultralight trigger pull for increased accuracy with the benefit of takeup that only a two-stage trigger can offer. The trigger features a flat-bladed design which blends well with the reduced angle pistol grip that the TREAD has. In addition to these upgrades, the SIG TREAD Snakebite SE still carries over the same great durability that its Cerakote finished receivers and barrels offer and will be 100% backward compatible with all currently available SIG TREAD accessories.

The barrel features a full-length high-temperature FDE Cerakote and a 1:7 twist rate for pairing with heavier grain bullets (77-grain). This is in stark contrast to the more versatile 1:8 twist tread models. Much like the other TREAD models, the SE version of the Snakebite comes with fully ambidextrous controls, and the Magpul SL-K stock.

The Snakebite SE starts with a unique flashhider/compensator component upgrade. The combo maintains minimal flash and reduced muzzle rise.

“We have a hybrid compensating flashhider,” said Patrick Hanley, Rifle Product Manager, SIG Sauer. “That’s right, this allows you to have the flash-suppressing ability while also having compensating in the top here to allow for reduction in muzzle rise.”

Meanwhile, a two-stage Matchlite trigger delivers an ultralight trigger pull. Featuring a flat-blade design specific to this model of the Snakebite, the trigger should help keep shooters on target.

The heart of the rifle then comes via a high-temperature FDE Cerakote-finished barrel. Measuring 16 inches in overall length, it features a 1:7 twist for stabilizing some of the popular, heavier 77-grain bullets on the market

A PDW grip, SLK stock, ambidextrous controls, and free-floating handguard with M-LOK attachment round out the complete rifle package. Like all SIG TREAD models, the new Snakebite SE works with the full line of TREAD accessories. For even more info, please visit
