Reviews & Ratings for Kaw Valley Precision Blast Shield for ASR — 13 reviews — Page 1

Protects my ASR threads and acts as a very good linear comp.

Wouldn’t hesitate to buy again. This is only the cover but it fits and feels like quality material.

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.

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.

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

Fits great, feels good. Flash can, and nothing else.

Works good, easy to swap with the ASR thread. Nice quality and with the money.

Seems to work and fit just fine. I believe the bore is .5 inches.

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).

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.
