TriggerTech Rem 700 Primary Trigger (Flat or Curved) – photos may depict flat triggers with shoes; they no longer have shoes
The Rem 700 Primary is the ideal upgrade to improve accuracy and precision on any Remington 700 model rifle. Featuring TriggerTech’s Frictionless Release Technology™, this drop-in trigger provides a true zero-creep break, extremely short over-travel, and offers outstanding reliability, even in the harshest environments. Utilizing CLKR Technology™, the pull weight is quickly and confidently adjusted from 1.5 – 4.0 lbs in 1oz increments from an externally accessible set screw.
Due to the exceptionally crisp break, most shooters report the pull weights feeling ~0.5lbs lighter than a friction-based trigger of the same measured pull weight. Frictionless Release Technology™, along with hardened 440C stainless steel internal components, ensures corrosion resistance and an extended service life. As Frictionless Release Technology™ does not rely on coating, polishing, or lubricating the key engagement surfaces, trigger pulls will be more consistent from shot to shot and after thousands of shots, more than you ever thought possible.

Why the 8.6 Blackout Rifle is a Game Changer
The 8.6 Blackout rifle has taken the industry by storm, often referred to as the “Big Brother” to the .300 Blackout. By utilizing a fast twist rate (available in 1:3 or 1:5), this rifle stabilizes heavy, sub-sonic projectiles with immense rotational energy, resulting in devastating terminal performance on game.
Our CM7S build is designed to maximize these ballistics. With a 16″ barrel and a total weight of just over 6 lbs, it provides the perfect balance of maneuverability and stability.

Optimizing Your Build: Subsonic vs. Supersonic
When choosing your 8.6 blackout rifle, the twist rate is a critical factor. The 1:3 twist is specifically engineered to maximize the rotational energy of heavy subsonic rounds, making it a favorite for suppressed hunting. If you plan on running a variety of ammunition, the 1:5 twist offers excellent versatility.
To complete your setup, explore our CM Suppressors to take full advantage of the 8.6 BLK’s quiet yet powerful nature. For those looking for a more compact footprint, check out our CM7S Bolt Action Pistols.

Frequently Asked Questions (FAQ)
Q: What magazines does the 8.6 Blackout Rifle use? A: Our CM7 chassis is designed to accept standard AICS-style (short action) magazines, which are widely available and highly reliable.
Q: Can I use a suppressor with this rifle? A: Absolutely. The 16″ barrel comes threaded in 5/8×24, the industry standard for .338 and .30 caliber suppressors.
Q: Why choose a 1:3 twist rate for the 8.6 Blackout? A: The 1:3 twist rate is designed to spin the heavy .338 projectiles at incredibly high RPMs. This results in better stabilization for subsonic rounds and massive energy transfer upon impact.
Q: Is the CM7S action compatible with other Remington 700 parts? A: Yes, the CM7S uses a Remington 700 footprint, meaning it is compatible with most R700 triggers, bases, and stocks (though it comes standard with our premium CM7 chassis).
Q: What is the lead time for this rifle? A: Lead times are approximately 2 weeks, as each rifle is meticulously assembled and inspected to ensure match-grade performance.
