Review: Strike Industries Cookie Cutter Comp .300 Blackout/.308

A while back Strike Industries introduced their Cookie Cutter Comp in 5.56, I got a chance to take a closer look at one in .300 Blackout/.308. Admittedly the Strike Industries Cookie Cutter Comp has been sitting on my workbench for a while now, I didn’t have a .30 cal gun that had the correct 5/8×24 thread pitch. I guess this was as good of an excuse as any to pick up a .300 Blackout barrel and put together a SBR upper more suited to taking down feral hog here in Texas.

One of the stock photos from the Strike Industries product page shows how great the brake looks with a carefully chosen handguard. After I dug through my bin of parts I came up with everything else I needed to assemble my test upper, unfortunately the rail I planned on using was 10″ long and the barrel was only 8″, I guess I don’t need a handguard to shoot it as long as I keep my hand clear. 18_5

Taking a look at the specs from Strike Industries site it covers everything pretty well.

Product Spec 300BLK / .308
– O.D.: 2.14”
– Weight: 7.90 oz
– Thread: ⅝” x 24
– Materials: Steel
– Color: Matte Black

Package include
– 1 x .223 Cookie Cutter Comp.
– 1 x .300BKL / 308 Cookie Cutter Comp.

-Large Single Gas Port expels gas on both right and left sides.
-Heavy-duty parkerized finished steel construction
-Unique functional design.

The Cookie Cutter Comp features a large single chamber design. It also has some small ports to the front of the brake situated between the crenalations. Strike was kind enough to include a crush washer, good thing because I couldn’t find the right size in my bin of parts. P1020105

The crenalations also make a decent glass breaker, if you are into that sort of thing.  P1020104

Instead of having users insert a tool into the chamber to tighten the brake on Strike included flats for a wrench. P1020106

Time to get it out onto the range. My upper looks pretty funny without the rail attached, it still shoots though. I must admit, the Cookie Cutter’s 7.9 ounces are kinda noticeable. cookie

Taking my first shots with the Cookie Cutter produced quite a noise. Strike warns in the product description “It is NOT a flash suppressor. There will be significant side concussion so the shooter needs to be aware of hand placement and surrounding personnel!!!P1020137

The Cookie Cutter does a wonderful job at keeping the recoil to a minimum.P1020127

My only big grip with the Cookie Cutter is it’s considerable weight and bulk. When I tested the Triple Crown Comp from Strike they were able to provide some pretty outstanding results with a lot less bulk and weight. P1020147

Strike Industries normally hits a home run with their products, I am not sure this is one of them. I am sure that there is some need out there that I am not seeing. It does look pretty cool though, I guess that is a great reason to buy one for your rifle.

The Cookie Cutter carries a MSRP of $59.95. You can read more about the Cookie Cutter Comp on the Strike Industries website here.

    You should probably pick a hand guard for that already. You could put a Noveske flaming pig style device on the muzzle and then use your 10″ rail.

    • Patrick R.

      I have a hand guard, it just wouldn’t work for the testing. A 10″ handguard would hide the muzzle devices. The handguard works fine with a suppressor though.

  • thedonn007

    I was hoping for a night shot of the flame emitted by this thing from a SBR .308.

  • whskee

    It looks like it belongs on some futuristic ray-gun in a movie. Prop house armorers, this one is for you.

  • Vitsaus

    … and Strike Industries gazed upon their muzzle brake and wept, for there were no more sharks left to jump…

  • manBear

    A 7.9 ounce comp. In case you wanted to shoot and knock out arm day all at once.

    • Jwedel1231

      You say that like its a bad thing 🙂

      • manBear

        Of course not! I’m tryna get swol brah

  • Guys I have used this on a short barrel and it looks fine works fine. Not so much on a 16 inch barrel but everything has it’s place.

    • Mrninjatoes

      Hey Phil.

      It seems like it would shine on a shorty platform. Thanks for your insight.

    • Secundius

      @ Phil W.

      At least with a 16-inch barrel, if ALL ELSE FAILS. Can be used as a WARHAMMER…

  • Lance

    Waste of time and money. Get a Flash Hider!

  • Cal S.

    Yeah, it’s definitely lacking in the “Second kind of cool” as Nutn says on anything but a full-length rail system.

  • Edeco

    I’d have called it the potato-masher, reminds me more of a potato-masher, tho that is the nickname of a grenade already.

  • Jeff Heeszel

    I’m surprised they didn’t make it out of aluminum. Half a lb. of anything hanging on the tip of a gun is going to reduce recoil.

    • iksnilol

      Probably made it out of steel since it is intended for short barrels. I think alu would wear away quicker on pistol length barrels.

  • James K

    I like mine on my AR pistol. (.223) Almost no recoil but big fire ball / concussion.

  • Bruce

    I continue to not understand the need for a comp in intermediate cartridges. I guess it’s all for fun anyway.

    • Jwedel1231

      Well, “need” is a strong word. “Need”? Probably not. “Legitimate reason”? Sure. It takes a gun that doesn’t kick much and nullifies it. My AR has less recoil than my 9mm handgun, that’s plenty of reason for me.

  • iksnilol

    Yes! The no handguard/rail thingy is gaining traction.

    • Patrick R.

      I hope not. I burnt myself several times testing this chunky muzzle brake.

      • iksnilol

        Well, was it the brake’s fault? If so I should be in the clear since I don’t use brakes.

        I am thinking ultra lightweight 300 BK SBR. That way the balance shouldn’t be too screwed. And it is a pretty decent weight saving.

        • Patrick R.

          No, it was a result of the bare barrel.

          • iksnilol

            Did you keep your hand a bit high, it seems like it is resting against the upper a bit? At least from the pic I can see.

            Please man, don’t ruin this dream for me. It could revolutionize the way we think about lightweight guns. Like for instance on an AK the dustcover is not needed, neither is the gas tube, and it is not like you use the handguard if you’re shooting accurately. I should move to the US and market this for all it is worth 😛

          • jcitizen

            I think it looks awesome in that shot where the forearm tube meets with it. Reminds me of the Bergmann MP18 or whatever they called those German trench brooms late in WW I .

  • Bill

    Sometimes I think guys doodle out something and just wonder how many of them they can sell. I also wonder exactly how well it would break glass, though punching near half a pound of steel into a window is likely to do it, just not the same mechanics as a center punch or GAT.

  • I keep looking at this comp for my 300 BLK pistol because, with a 10″ barrel the overall length comes in at 25.5″. I’d rather have an A2 or something else, but it’s not easy finding a muzzle device as short as this cookie cutter comp. I’m open to suggestions if anyone has one.

    • Cymond

      If you want a small brake, look at the Rainier Arms RMC. They used to make a 30 cal version, maybe you can still find one.
