Surefire Warcomp 5.56MM 1/2-28 closed tine

The revolutionary Surefire Warcomp 5.56MM 1/2-28 Flash Hider/Suppressor Adapter, which fits M4 / M16 weapons and variants with ½-28 muzzle threads, is the world’s most shootable flash hider. Its patent-pending design provides three valuable functions:

also consider the flash hider version here  

  • It provides over 99% reduction in muzzle flash compared to a plain muzzle, which helps to conceal the shooter’s location and preserve his dark-adapted vision.
  • It virtually eliminates muzzle rise, which enhances monitoring of target reaction and staying on target for faster follow-up shots.
  • It serves as a rock-solid mounting adapter for all SureFire SOCOM Series 5.56mm Fast-Attach® suppressors, including our SOCOM556-RC model, which placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command.

Also consider the open tine version of the Surefire Warcomp here  

And the Q Cherry Bomb Muzxle Brake here.

Precision machined from US Mill-certified heat-treated stainless steel bar stock — including high-precision single-point cut threads for optimum thread interface — the WARCOMP-556-1/2-28 features an Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use.

When used in conjunction with a SureFire SOCOM Series Fast-Attach suppressor, the WARCOMP provides multiple bearing surfaces to ensure superior suppressor alignment and prevent any ringing of tines inside the suppressor. A rear labyrinth seal mitigates gas leaking from the back of a suppressor, minimizes potential carbon buildup in the indexing system, and facilitates suppressor removal after extended firing. Every SureFire WarComp is individually inspected for concentricity and alignment.

For rock-solid mounting of a SOCOM Series suppressor, unparalleled flash reduction, and minimizing muzzle rise, there’s literally nothing like a SureFire WarComp—the world’s most shootable flash hider.

    Originally placed an order for the other warcomp flash hider Will contacted me immediately to inform me that it was out of stock. He advised me that he can place an order for the bird cage warcomp but will take extra time to be shipped. Bought it along with the surefire training can I just installed both. Im Glad my previous order was out of stock beacuse this looks alot better. Thanks Will!

    You bet! Thanks for the order!

    I called in and spoke to Will for an order update on the warcomp. I finally got it due to back orders. Once I got the warcomp I noticed the perfect quality and detail features of the muzzle. I’m glad I made this purchase from megiddotacticalgroup. They had it in stock when other dealers didn’t.

    Product works as it should. No issues at all. Customer service is excellent! Will is friendly and communicate very well. Thanks

    Works wonderfully. Not quite as good at flash suppression as the open tine version and it can only be timed neutrally, but those are fair tradeoffs for a sturdier muzzle device. MTG’s service is great as well, very quick shipping.

  6. JR (verified owner)

    Bought one to pin and weld to a 14.5″ AR to avoid having to pay Uncle Sam $200. It is very easy to pin and weld. These closed tines version doesn’t ring like the open tine but doesn’t have quite the flash suppression the open tine version has. DLC coating is awesome, you’ll never have to worry about it. More to come once I get to the range.

  7. Daniel Kim (verified owner)

    Runs well, seamless integration with the qd wardens as designed. Works well, MTG is good to go with quick & direct cs, shipping, & info.

  8. Dano (verified owner)

    Runs great, switched things up from the 3 prong warcomp and satisfied. Used frequently with and without a warden, no complaints. Ordered twice at different times and had packages at the door within a week.
