Questions & Answers
Can I use the 308 on a 300 blackout Expert Answer

Yes, the .308 Spikes Tactical ST Dynacomp Extreme Suppressor will function as intended with 300 Blackout. Both 300 Blackout and .308 have the same bullet diameter, meaning any muzzle device that works with .308 will also work with 300 Blackout.

can this be pin and welded on 13.9 inch barrel? Expert Answer

The Spikes Tactical ST Dynacomp Extreme Suppressor is 2.25" long. So it could be pinned and welded to a 13.9" barrel.

Best Muzzle Device for the range by Brian, Verified Owner, April 6, 2024
I own quite a few muzzle devices and this one is the best by far for control of muzzle rise and recoil without offending everybody else trying to shoot at the range near you. I own 3 of these for 5.56/223 and 1 for 7.62x51/308 and worth every penny....

Great Recoil Reduction .300 Win Mag by Scott, January 17, 2025
Easy install on my 300 win mag and significantly reduced the felt recoil of the cartridge. I actually enjoy shooting the rifle now. The only downside, which is to be expected with any muzzle break, is the additional decibel increase. No way around it...

Product Info for Spikes Tactical ST Dynacomp Extreme Suppressor

The Spike's Tactical Dynacomp is a muzzle brake designed to redirect muzzle blast in a manner that reduces both recoil impulse and muzzle climb to provide faster follow-up shots. The ports on these AR15 Muzzle Brakes & Compensators by Spike's Tactical are ball dimples for smooth expansion of gases and rapid heat dissipation, and the front of the device is 0.25in thick to better handle the abuse of full auto fire. The direction of the blast on the Dynacomp is balanced along vertical (upward) and perpendicular planes of the muzzle to lower muzzle rise in order for you to have a steadier shot. Equipping the Spikes Tactical Dynacomp Muzzle Brake will help balance the direction of the muzzle blast along those same planes, lowering muzzle rise and providing a steadier shot.image
