Answered by Ethan, Gear Expert, from IL, United States, on August 30, 2022

Yes, 6.8mm Remington SPC has a bullet diameter of 0.277" while this VG6 Precision Lambda PRS30 Muzzle Brake is bored for .30 cal, making it compatible as long as you have 5/8x24 threads.

Will this work on a 7.62x39?

Answered by Brandon, member, from UT, United States, on January 11, 2021

Caliber wise, yes, but fitment of this brake will depend on your thread pitch. Assuming we're talking about an AK, most AK's don't have 5/8x24 thread pitch. Check out the VG6 Precision Episilon AK, threaded M14x1 LH specifically for AK's.

Not at this time, the Lambda is designed as a stand-alone PRS muzzle device. VG6 Precision is currently finalizing the design of a blast forwarding device.

This muzzle device as it is would not be safe to use with a .458 SOCOM rifle. It would need to be bored out in order to use it with that caliber.

If the barrel is 5/8x24 threaded, yes it should absolutely work.

Q
Charlie, member, from NC, United States, asked on October 01, 2020

Is there a model with this jam nut for the 5.56/.223 round?

A
Answered by Brandon, member, from UT, United States, on January 11, 2021

There is not. The thread pitch also isn't going to be compatible for most 5.56/.223 caliber rifles - you would need 1/2x24 thread pitch. You would also be losing a lot of the effectiveness of a muzzle brake by having an oversized caliber brake. I would recommend the VG6 Gamma or Epsilon in conjunction with the VG6 CAGE for a similar effect.
