9mm Micro Comp + Thread Protector

(12 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).

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

    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.

    Great product at such a great value.

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

  6. Johnny Salaza (verified owner)

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

  7. 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

  8. 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.

  9. Derek Wride (verified owner)

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

  10. 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

  11. 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!

    Looks amazing on my scorpion.
