The Lancer Systems Nitrous Compensator, .308/7.62, 5/8×24, Black Nitride (Lancer part no. LNC-308-BK) is a tunable compensator and muzzle brake designed for competitive shooters. A blast chamber and adjustable jets redirect gas to reduce muzzle climb and felt recoil, so follow-on shots come faster and more consistently. This version is threaded 5/8×24 for .308/7.62mm rifles and carries a Black Nitride finish. It is a natural fit for 3-gun, PRS-style and range builds where you want to tune how the rifle recovers.

Key Specifications

• The compensator is built for .308/7.62mm rifles, so it matches the bore and thread of AR-10 and similar platforms.
• Thread pattern is 5/8×24, the common .308 muzzle thread.
• The finish is Black Nitride, a hard surface treatment that stands up to heat and cleaning.
• Two adjustable jet locations at the 12 o’clock position direct gas upward from the blast chamber, creating downward force on the muzzle to counter climb.
• Angled blast baffles reduce recoil and stabilize the rifle.
• The jets are tunable, and Lancer specifies tightening them to 8-10 inch-pounds after each change.
• It includes a crush washer, wrench and adjustable tuning jets, so you have the mounting hardware you need.

Frequently Asked Questions

How do I tune the Nitrous Compensator? Shoot rapid strings of three to five rounds offhand at 25 to 50 yards. If the group strings upward, fit larger-orifice jets; if it strings down, fit smaller ones, torque both jets to 8-10 inch-pounds and repeat until the group holds at the same elevation.

What thread and caliber does this one fit? This version is for .308/7.62mm rifles and is threaded 5/8×24 with a Black Nitride finish.

Should I tune it from the bench? No. Lancer says to tune it shooting rapid strings from an offhand position, not from a bench or a supported position, and to confirm the firearm is unloaded before adjusting or replacing the jets.
