Fake Can/Suppressor (Reverse-Style) - M4-Style-1/2"-28 and 5/8-24 FREE shoulder-less thread adapter

In stock

Special OOPS Promo

These fake cans are threaded for 5/8-24 however they say 9mm.

We are including a free 5/8-24 to 1/2-28 shoulder-less thread adapter to make them work on nearly any platform.

Once installed, you cannot see the shoulderless adapter the product looks like a normal 1/2-28 fake can, just with fu^^y markings.

This is basically a condom for your barrel. If your AR is going to be sexually active then you need this... Safety first. You can get pregnant or an STI with just one shot.

Seriously though, here's the scoop. A reverse-style fake can is basically a shroud that looks like a silencer, your barrel slides in the back and goes all the way to the front where it screws into threads. In this way it makes it look like your barrel is much shorter and has a suppressor. Some people have trouble imagining it so I made a drawing:

You'll need at least 125mm of space from the gas block front to the muzzle thread shoulder.

  • Billet aluminum construction

  • Not designed/intended to affect sound or flash
  • Slips over the barrel so it does not increase the length

  • Knurled base
  • 5.5" overall length × 1.24" diameter
