Spike’s Tactical Compressor ST

Spike’s Tactical brought out their Compressor ST out at Big 3 East last week.

At first glance it looks like any other suppressed SBR AR. That is until you start seeing the subtle attention to detail.



The gas tube would over heat due to the length. So they solved this by wrapping the gas tube with beryllium copper wire. It acts like a heat sink to dissipate the heat away from the gas tube. They also machined the barrel with WWII style cooling fins. Mostly for aesthetics but they do work in cooling down the barrel.



The Compressor lower has some striking details such as the flush ambi controls and the flush anti-roll pins by KNS made specifically for Spike’s Tactical.DSC_0053 DSC_0056


Handling the Compressor, you can feel the quality of the build. This gun was rather popular and when it was my time to shoot it, it was a bit too hot. So they handed me their other Compressor to try out.


The Compressor ST retails at almost $3,000. Check out their website for more info.

    I`m digging the receiver set and the wrap on the gas tube. But the rest is pretty meh. Especially that generic rail.

    • Nicholas Chen

      Yep, my thoughts exactly. The rail is bland. I cannot think of another

      handguard of a better design that allows suppressors to fit underneath

      • JumpIf NotZero

        ALG for one.

      • An Interested Person

        Since it`s a custom upper anyway, they could have done what MEGA did and have the handguard bolt to the upper with a visually appealing transition. Or at least gone for something in Keymod or MLOK. Rails are soooo 2k14.

      • NDS

        Seekins MCSR is specifically designed for this. It’s very light, keymod, and sub-$200

  • G0rdon_Fr33man

    Fashion statement?

  • hami

    The flush anti-roll pins are very cool. Ugly, but very very cool.

  • Dracon1201

    I want to know if they will make more AR barrels with cooling fins.

    • RealitiCzech

      Green Mountain Rifle Barrel Co makes one – GM-M11.

      • Grindstone50k

        If only they were shorter barrels. They do look pretty awesome.

        • RealitiCzech

          True. I’d love one for my AR pistol.

  • KestrelBike

    Ok that is dead-sexy.

    “The gas tube would over heat due to the length. So they solved this by wrapping the gas tube with beryllium copper wire”

    Well.. That’s A solution to your problem… The better one imo would be to not make a 7.5″ 556 because it’s dumb considering 300blk stomps all over it. If your gas tube is over-heating, you’re doing something very dumb, the effect is less important than the cause, they seem to want to treat the effect.

    A more pressing issue I would be concerned about for them is their logo. Have they changed that yet? Once you see two dongs instead of a spider – you can’t unsee it.

    • Chijen

      LOL. That logo would make a great psyche test. Do you see a spider or two male genitalia barely touching??

      • Joshua

        Male genitalia……always male genitalia.

        • Rex Krom

          Just the tips…

    • Giolli Joker

      Very true about the logo… I was in a very comfortable arachnid world until I read somewhere about the dueling manhood… now I’m doomed.

    • Rex Krom

      Isn’t this rifle chambred in .300 BLK? The description in the video says it is but the link to the website takes you to the 5.56 model.

  • RealitiCzech

    They used a Magpul AFG on a gun designed to bleed off the heat as fast as possible? This is exactly what vertical foregrips were invented for – so you can shoot without gloves until it gets very hot, and at the end you will still have fingerprints.

  • Grindstone50k

    Are the flush parts actually machined down or is the receiver just machined around the parts that would stick out on a normal lower?

  • sam

    I’m not convinced with the Be copper wire. I’m not convinced that it’s the best alloy. It might be, I dunno. Also the idea of wrapping with wire: Are we sure it’s coupled to the tube for efficient heat transfer and will stay coupled for a long time? There’s a little still air underneath the coils right, like where the coils meet? Or do they do something about that?

    Perhaps there’s genius to it I’m not seeing, but at first glance it seems like the idea is only half-cooked, and maybe a little gimmicky.

    • Joshua

      Tom who is the owner is FOS. Sorry but I’m just going to say it, he was on a certain gun site claiming how all of SoF and SF was using these guns back in 2011, back before I retired.

      I called him out as wrong and he went ahead and deleted my post and banned me from his sub forum.

      I would take everything thing he says with a mountain of salt.

      • sam

        Hmmm, interesting.

        Also interesting about beryllium , I didn’t realize high mass specific heat capacity. Still tho, BeCu…

    • RealitiCzech

      It’s a decent choice, I suppose. The specific heat of beryllium is pretty high, so it takes quite a bit of heat to raise the temperature. This is why water cooling was used back in the day (and is used in automobile engines), the specific heat of water is also high, so heat is reduced.
