This is a 16″ .388 Spectre rifle from Chattahoochee Munitions. This will be one of the sturdiest feeling weapons as everthing is designed in tight tolerances. All of our rifles are equipped with HIPERFIRE (High Performance Firearms) Triggers; all are 2.5lb single stage Reflex (curved) or Competition (straight with shoe); Reflex is pictured. Superlative Adjustable Gas Blocks are standard on our rifles.

History of 338 Spectre

Marty ter Weeme of TEPPO JUTSU invented and developed the 338 Spectre as a dual purpose round, much like his 458 SOCOM round in early 2001. The parent case is that of a 10mm Magnum, which is a lengthened 10mm case and should not be confused with the shorter round. The case is necked down to accept a .338″-diameter bullet and this in turn offers quite an array of projectiles for the reloader and shooter.

Early prototypes and development of upper receivers used integral suppressors for sniper security teams and other clandestine operations. This was easily accomplished because of the low gas volume generated by the 338 Spectre which makes it an ideal cartridge for use with suppressors.

What is it good for?

This extremely versatile round is useful in many situations from law-enforcement and military scenarios to hunting medium-sized game at close distance to casual or professional level target shooting applications. In many ways, this round is superior to the 300 Blackout.

The case head shares the same dimensions as the 6.8 SPC rifle cartridge. Likewise, 6.8 SPC rifle magazines will hold a full payload of cartridges as opposed to 5.56 NATO magazines which will hold a reduced amount. AR magazines intended for 7.62 x 39mm will hold the full number of rounds intended as well.

For the subsonic loading, a 9mm pistol suppressor will suffice to keep it quiet. Suppressors such as this are much cheaper than the heavy duty suppressors intended for 338 Lapua Magnum. (Check with suppressor manufacturer to verify rated for 338 Spectre if using any other than a Hybrid 36 or 46, or 338 can.)
