9mm Micro Comp + Thread Protector

(30 customer reviews)


In stock


An extremely versatile thread protector for your 9mm pistol, rifle, or SBR. Our 9mm Micro Comp + Thread Protector is designed to be short, lightweight, and 100% functional as both a compensator and thread protector. The backbore and radial porting create “neutral bias” compenstation when fired. The deep precision cut threads and a high temp silicone o-ring hold the device securely in place through endless hot/cold cycles. The taper machined groves on the outside diameter provide tons of grip for toolless removal and installation.

If you are tired of checking your thread protector between magazines, or just looking for the most compact comp on the market, our 9mm Micro Comp has been designed and manufactured specifically for you.

Our 9mm Micro Comps measure 0.75″ outside diameter, 0.80″ long, and 1/2-28 thread is 0.63″ deep. They are machined from 4140 steel, heat treated, and finished in black nitride. Weight is just 0.62 oz (for reference an A2 spec flash hider weighs 2.20 oz and a 1/2-28 3lug adapter weighs 0.75 oz).

    Looks amazing on my scorpion.

  2. Brian Doyle (verified owner)

    I purchased 2. One went on my Stribog Gen2 and the other onto my Kriss Vector SDP. They stay tight and don’t back off when shooting like some comps I’ve tried.
    These mini comps are fantastic and at a great price, grab a few and try them out!

  3. Cotye Wehrle (verified owner)

    I put on my stribog and love it. Small and sleek does help mitigate muzzle rise, has stayed tight for over 400 rounds. I’ll be ordering another for my pistol

  4. Derek Wride (verified owner)

    Seriously cool product. Looks great, and can still holster without any fuss.

  5. Rustin Osborn (verified owner)

    I bought this comp for my StriBog gen 2. Awesome little comp. My only critique would be that it’s extremely tight. I was afraid I had the wrong thread pitch but just have to continue twisting.

  6. saico (verified owner)

    Too bad they’re out now. I have 4 and they’re great. About half price of what others are charging for a mini comp

  7. Johnny Salaza (verified owner)

    Awesome design at a great price! My only regret I only ordered two and now they are out if stock…

  8. Robert Bonalba (verified owner)

    I just received mine, it looks good on my Ruger PC Carbine 9mm. Can’t wait to try it out.

    Great product at such a great value.

  10. David Sanders (verified owner)

    Best micro comp- ever. Threw this on my vector gen 2. Looks amazing. Tried it on my POF- 5 mp5 and fit perfect and looked great.

  11. Parker

    Shipped next day after ordering and fits nicely on my stribog.

  12. JohnDy (verified owner)

    Love this, great product for a tremendous price! Everything I have purchased from HBI has been top shelf, thanks!!

  13. Matthew Johnson (verified owner)

    Exactly what I was looking for. Does what it’s supposed to do as a compensator, while looking good plus, a nice finish. Also keeping it purpose built, small & simple, which is just perfect for my compact PDW, a RUGER PC Charger.
    More importantly I can take it off quickly to suppress & put it back on as a really nice thread protector. Good Job!!

    I bought this product recently. It does provide a lower profile to the barrel. I am extremely pleased with the way this turned out. The shipping was extremely fast. I would recommend.

  15. David Yount

    I ordered one for my scorpion with HB I three-lug k kit on it….works and looks amazing like it came from factory. I ordered two more of them….one for freedom ordinance fx-9 pistol, and one for keltec sub 2000. Had to use a crush washer to fill the gap on fx9 pistol….looks great.

  16. Joshua Bell (verified owner)

    A+ product, fast and cheap shipping. Looks and functions great on my Sig P365XL

  17. Edgar Berganza (verified owner)

    Awesome little piece! Looks great on my P10C and STAYS on! Can’t wait to take some shots!

  18. Jeff Wrede (verified owner)

    I own the Canik TP9 Combat Elite Executive and having to use a wrench every time to remove and reattach the thread protector is a pain. When I saw this Thread Protector from HB Industries, I immediately loved the look, and when I discovered you can take it off and put it on without a wrench, I was sold and ordered one. Now that I have it, it’s fabulous! Excellent quality! Highly recommend!

  19. Nathaniel Levi Watson (verified owner)

    Great comp for the money although I made it better with modifications, I removed the lip holding the rubber ring in and replaced the ring with a thinner one now the comp threads deep enough it covers the barrel slightly leaving only the port holes sticking past the end of the muzzle threads. Giving an overall shorter length on the end of my p10c but still seats solid and doesn’t back off.

  20. Thomas Smith (verified owner)

    A very good compensator for my Scorpion SBR. the front hand stop shows blackening from powder, My hand usually shows a u shaped white spot in black after a field day. It helps recoil though and keeps you on target through fast strings. My suppressor has more recoil.

  21. Jason (verified owner)

    These are awesome. I just bought a 3rd

    **Important Personal Install Notes & Reivew** I had an interesting experience with this compensator. I purchased it to put on my Scorpion Evo 3 S1. However, when it arrived, and I took the stock compensator (1) and barrel thread protector, I realized that with the stock compensator catch (Part 89 on the exploded view) wrapped around the barrel nut (2) left on and in the original position, the microcomp looked goofy because of the exposed threads that the stock compensator used to thread onto the barrel. Clearly this wasn’t right, so I put the Micro Comp aside to figure out another day.

    Fast forward a few months, and I was disassembling my Scorpion to do a deep clean, remove built up carbon, etc. Ultimately this included taking off the HB Aluminum handguard, which revealed the barrel…. and also gave me reason (and leverage) to *remove the barrel nut and the compensator catch*, which required a significant amount of torque. I ended up taking it completely off, as it was clear that it and the corresponding barrel threads had a ton of loc-tite on them. After cleaning everything first with an ultrasonic soak in 50% strength Simple Green Aircraft then a stainless steel wire brush on the inside of the barrel nut to remove the loctitc, I took off the awkward looking stock compensator catch and began reassembling… I reapplied loctite to the outermost threads for the barrel nut, and threaded it on so that *no large threads could be seen*. At that point, I screwed on the Micro Comp until it hit the barrel nut, and…. Mission Accomplished!! That little sucker works great, looks smaller and more modern than the stock compensator, and the O-ring holds it in place. Form and a functional upgrade by not having to worry about the thread protector loosening, all for 20 bucks. I highly recommend them.

    Got it on my Canik TP9SA and love it. Shared on Canik Nation so you’ll be getting some orders soon from those guys.

  24. Greg Young (verified owner)

    Most Excellent! Made an immediate difference! Did my homework and the 9mm Mini Comp from HBI is a real value and design. Many Thanks to you HBI.

  25. Tyler Frizzell (verified owner)

    The Future is now. That’s what I’m coming to realize with shooting. In order to continue evolving as a shooter, we must be able to adapt to new equipment. I bought the MicroComp more as a thread protector first, compensator second. A friend recommended it, and at $20 I figured why not. I am using it on a Gen 1 S&W 4.25 M&P 9MM. I am using a Storm Lake barrel. It reduces felt recoil noticeably and makes follow up shots a breeze. It does not seem to induce malfunctions and I’ve shot 115, and 124 grain ball and some defensive ammunition. Good To Go. Fits holsters I already have with no modification. Will recommend and will buy again.

    I went to the range with it on my Scor-Bog and left with it on my P365. It made a noticeable difference on my p365. Awesome upgrade for under 30 bucks.

  27. Joe Kump (verified owner)

    Received this micro comp last week for my CZ P07. Easy to install and the handgun shoots great. Would Highly recommend.

  28. Matt

    Great muzzle device, exact diameter of the Stribog barrel.

  29. Chris S (verified owner)

    Get one for every 9mm in the house and consider it a fancy thread protector. Very handsome craftsmanship. Fit is fantastic and it’s barely noticeable. For those owners that like to keep it stock this Micro Comp retains the same profile as the standard stock thread protector. Shipping was fast!

    Looks tits on my glock build
