The MCX Spear is now fit for public consumption.

SIG Sauer’s MCX-Spear will soon be available for the general public to purchase.

This is the same great platform that won the Next Generation Squad Weapon (NGSW) contract with the U.S. Military, but with a twist.

The MCX-Spear that is sold to the public will not be full-auto select fire, unfortunately, and they will be available in 308 Winchester, 6.5 Creedmoor, or .277 Sig Fury.

You can expect to be able to purchase the MCX-Spear chambered in .308 and 6.5 Creedmoor before February, while it will take a bit longer for the .277 Sig Fury chambering to hit the shelf.

The MSRP is going to be $4,199.00, so start saving now!

There are flush-cup sling attachment points at the front and rear of the MCX-Spear.

Interestingly, the military’s MCX-Spear will have a 13.5-inch barrel. Unlike the military’s, the civilian MCX-Spear will come with a 16-inch barrel. With one exception, there will be a .308 pistol offering that comes with a 13-inch barrel.

One advantage of the MCX-Spear is the ability to swap the barrels easily and change the caliber. This allows you to buy a 6.5 Creedmoor MCX -Spear, plus a .308 Winchester barrel and a .277 Sig Fury barrel, and change the platform back and forth between the three.

And of course, the Spear’s muzzle is threaded in the common 5/8×24 TPI for mounting suppressors or other muzzle devices.

SPECS MCX-Spear

  • Caliber: 277 SIG FURY / 6.8 x 51
  • Overall length: 34.1 inches
  • Overall height: 7.97 inches
  • Overall width: 2.98 inches
  • Barrel length: 13 inches
  • Barrel Twist: 1:7
  • Weight (w/magazine): 8.38 lbs.

The MCX-Spear has basically the same controls as the MCX, but it also comes with an ambidextrous safety and two charging handles. You have the same rear charging handle as you would find in the familiar AR platform, as well as a side charging handle that is non-reciprocating and lays flat against the rifle when not in use.

This rifle has a short-stroke gas piston with two gas settings; suppressed and unsuppressed. Because the bolt and gas system are totally different than traditional ARs, the bolt is confined to the upper receiver, and a folding stock is featured which doesn’t interfere with the function of the weapon when folded.

To round it out, the trigger is SIG Sauer’s match trigger with a pull between 4.5-6 lbs. As configured, it’s been noted to print groups of around 1.5 MOA consistently.

    No 5.56mm NATO?

      The whole point of the MCX-Spear is to provide a multi-caliber rifle (277 SIG FURY, 6.5 Creedmoor, 7.62 NATO) that has more power, distance, and accuracy than the 5.6mm NATO round.
