Kaw Valley Blast Shield

by Jason, Verified Owner from LA, United States Written on August 15, 2025
This fits perfectly on my SilencerCo 3 prong ASR flash hider. It looks great on my Daniel Defense ddm4v7(16”)! There’s about a half inch space between the back of the blast shield and the handguard when mounted. It goes on easy and comes off easy, even after several hundred rounds, just add a dab of barrel grease to the threads.

Versatile; Excellent fit & finish.

by 300BLKEnjoyer, Verified Owner from NM, United States Written on May 14, 2025
Excellent machining work and finish, especially at the price. the Kaw Valley Precision Blast shield for ASR fits all of my SiCo ASR mounts by just screwing on. Acts as a thread protector, and will save your headache at an indoor range on your shorter pistols or rifles. With a .50" ID at the exit, this will accommodate anything up to .46 caliber, easily. Buy with confidence! I'm probably going to get a few more.
Pros:
  • Price, machining, finish, style, quality
Cons:
  • None; it's excellent
Best Used for:
  • SiCo compatible ASR devices
Would recommend: Yes

Well, worth the money

by Q, Verified Owner from KS, United States Written on May 7, 2025
Used on gen 1 ruger american in .243 (58gr hornady vmax ammo) with 16in barrel. Substantial difference between sound placment. Keeps all blast down range and away from shooter. I use this setup for my ranching gun and needed less concussion towards me without giving up the versatility of a compact rifle. Works perfect for those "truck cab" area shots. Already have the asr muzzle break mounts on all my rifles, so this was an easy, inexpensive way to keep the brake and divert blast
Pros:
  • quick and easy
Cons:
  • None
Best Used for:
  • Compact rifles
Would recommend: Yes

Very pleased

by Tom, Verified Owner from VA, United States Written on March 8, 2025
This isn't to be used in place of a suppressor but it does direct a large portion of the blast and noise away from the shooter's ear.
This is assuming you are using this on a bolt or lever action gun.
This doesn't make it ear safe but I would definitely consider using this while hunting if I didn't own a suppressor.
I have this over a SilencerCo muzzle brake. I know I am probably loosing over half of the effectiveness of the muzzle brake but I really love the blast shield for what it does and how well it does it.
This is good for any experience level and is super easy to install over the ASR muzzle device.
I would encourage using some high-temp anti-seize on the threads before tightening.
This is going to have a tendency to carbon lock if you don't remove it and clean the threads at least every other range day.
I have tried other manufactures and this one is FAR more effective and better designed.
I have a ASR muzzle devices on a a few long guns and I swap a suppressor back and forth on them, this is what I use kind of as a "full-featured" thread protector.
Also this is way cheaper than SilencerCo's blast shield and this one is actually obtainable (due to being in stock and over half the price).
Pros:
  • Effective and good price
Cons:
  • can't think of one
Best Used for:
  • Anyone with an ASR muzzle device
Would recommend: Yes

Seems to work!

by Chairman Brando, from VA, United States Written on August 23, 2024
My 14.5" pin-weld PSA Sabre came with a SiCo ASR flash hider, so I was seemingly limited to exactly two options for a BFD to be used at indoor ranges: the official one from SiCo and this one from KWP. The "real" one was 2-3 times more expensive so I went for this one.

I've only put 100 rounds through it so far (40 .223 and 60 "NATO" 5.56), but it (a) stayed on the gun with simple hand tightening and (2) seemed to dull the blast by pushing it forward, saving the eardrums of those in the lanes next to me. That's about as much as I could've asked for and it delivered.

I didn't use any thread locker because I wasn't sure what would survive the heat, but I think that or an O-ring is the play to ensure it doesn't get shot down the range with heavier use. Or just wear gloves and make sure it's tight after every magazine.

Plus, it looks a lot cooler than the goofy three prongs hanging out there, IMO.
Pros:
  • Looks cool
  • Notably cheaper than the real thing
  • Forwards the blast as expected
  • Happier lane neighbors at the range
Cons:
  • Adds recoil as expected
  • May not stay put without intervention or thread locking
Best Used for:
  • indoor ranges
Would recommend: Yes

KVP Blast shield

by Mark, Verified Owner from FL, United States Written on May 8, 2024
If you have an ASR FH on your weapon look no further for a blast shield, this is precision made and goes on easily and better yet priced right is a slim profile and looks great.
I have not yet fired the rifles that I put the 2 I installed but by the looks of the quality manufacture there will be no concerns. These are tensioned in position only so make sure you check how tight it fits after every mag when you first use it, I snugged mine with a strap wrench, no tools needed to mar the finish. No different than when using a silencer always check that it's tight. Carry on......
Pros:
  • Simple, made well and priced right
Cons:
  • Time Will Tell
Best Used for:
  • blast shield and noise diversion
Would recommend: Yes
