View Full Version : Linear Comps, Flash, Dust, and Hearing Preservation

An upper built around a BCM 11.5" barrel is in my future. Primary use would be home protection, plus being easier to carry then my 16"on my ATV or in a vehicle. The ultimate answer to the following questions is probably a true sound suppressor, but finances for such are a long way down the road. In the mean time, assume that we hold ammo selection as a constant and the comparisons are between different muzzle devices. I'm thinking flash suppression to preserve my own low light vision is an important consideration.
I'm leaning toward a Smith Vortex for flash suppression. When used prone or in other unconventional obstructed positions, how does the Vortex compare to an A2 at kicking up dust? I note that the YHM Phantom 5C2 claims that their 5 port design minimizes dust when prone, but I'm leery of anything compensator or brake related due to the noise and concussion implications. This leads to my next issue:
I already wear hearing aids at age 54, and I'd like to save what I have left. The linear comps like the Levang or KRIES claim to reduce sound and concussion to the shooter by directing blast down range. I'm not looking for total sound reduction, just trying to protect my own hearing and the hearing of anybody next to me during range time. Any first hand experience with the linear comps? If so, what effect do they have on flash, and on kicking up dust when prone as compared to an A2?
I know there's no single perfect device. Just looking to add to what I've found searching other posts. Thanks for any input.

KX3, and try not to shoot without hearing protection.

A compensator like an A2 or Phantom is not detectably louder than something with slots all around.

I have two linear comps installed one on an 18" SPR and another on a 16" mid length. I have the Levang on the 16" and a Kaw Valley on the 18" http://www.joeboboutfitters.com/Kaw_Valley_Precision_22cal_Linear_Comp_1_2x28_Bla_p/kvp-linear223-blk.htm

Both reduce muzzle blast significantly. I tried the 18" without hearing protection for one shot and the buffer spring and action is louder than the blast. Not unlike a suppressed 9mm pistol using super-sonic ammo. Be aware I am NOT saying it is like a suppresed rifle, but is significantly quieter than a normal brake.

Not something I plan on doing routinely, but it does reduce the back blast sound signifcantly as said above.
