The SIG 50: SIG SAUER’s .50 BMG Rifle

SIG SAUER has unveiled their tactical rifle chambered in .50 BMG at the 2011 SHOT Show in Las Vegas. Nevada. The bolt action, magazine-fed rifle has a match grade 29″ barrel with a 1:15 twist. The stainless steel barrel is fluted to reduce overall weight and help cooling and comes with a custom-tuned Remington trigger system with pull set at three pounds, which is further customizable by a qualified gunsmith. The Duracoat finished fiberglass stock is pillar bedded and the barrel free floated.

The action itself is hand fitted to ensure the barrel axis is perfectly perpendicular to the bolt face. Superior ergonomics are achieved with a spacer system to allow the length of pull to be adjusted to fit the shooter and a fully adjustable cheek piece to promote proper cheek weld.

Recoil is relatively mild due to the MacMillan muzzle brake.

From the press release: “SIG SAUER, Inc., the leading manufacturer of commercial, law enforcement and military firearms, renowned for accurate, high-powered rifles, now offers the ultimate in big-bore, long-range power with the addition of the SIG50 bolt-action tactical rifle.

Designed with the shooter in mind, the SIG50 offers a match grade trigger that breaks cleanly at 3.5 pounds. Fully user-customizable ergonomics include an adjustable cheek rest and ergonomic pistol grip stock with a butt plate adjustable for length of pull. Additionally, the stock also detaches for ease of transport, yet locks up firmly to provide optimal support and strength.

A 29” heavy fluted barrel features a recoil-reducing muzzle break that minimizes wear and fatigue on the shooter. Weighing in at only 23.5” pounds, SIG SAUER has created the perfect blend between lightweight portability and manageable recoil.

The full length machined M1913 rails allow for rock solid, repeatable mounting of optics, night vision, bipods and laser designators. Designed with input from former military snipers, the SIG50 is a durable, accurate tactical rifle that delivers robust down range energy.”

  1. That’s totally different from the SIG .50 that I saw in March at IWA (Germany). Google SAN511 .50 you’ll see what I mean.
